In this work, we synthesized an acid-responsive zinc metal–organic framework (ZIF-8) at room temperature by a solvent method, which can not only be used as an antibacterial by releasing zinc ions but also as a carrier for antibacterial material encapsulation. Subsequently, the broad-spectrum antibacterial triclosan (TCS) was encapsulated in ZIF-8 by the impregnation method, and a long-term antibacterial and antimildew material with slow-release effect TCS@ZIF-8 was synthesized successfully. The encapsulation rate and drug loading rate of TCS@ZIF-8 prepared by adjusting the mass ratio of ZIF-8 and TCS were 71.9 and 25.1%, respectively. Further, TCS@ZIF-8 was introduced into polyacrylate (PA) emulsion, and PA/TCS@ZIF-8 nanocomposite emulsion was prepared successfully by the physical blending method. When the pH of the coating surface became slightly acidic due to the metabolic byproducts of microbial growth, ZIF-8 in PA/TCS@ZIF-8 disintegrated to release Zn2+ and TCS, which can effectively kill bacteria and mold. When the dosage of TCS was 4.0 wt %, the antibacterial rate of the PA/TCS@ZIF-8 nanocomposite film against Escherichia coli and S. aureus was 100 and 97.3%, respectively. Finally, PA/TCS@ZIF-8 nanocomposite emulsion-coated leather was prepared by the spraying method. Compared with the control group that did not use ZIF-8-encapsulated TCS, PA/TCS@ZIF-8 nanocomposite emulsion-coated leather not only showed better antibacterial and antimildew effects but also showed long-term antibacterial and antimildew performance even after being treated under hot and humid environments of 90% humidity and 40 °C for 30 days. Overall, this study not only provides theoretical guidance into the preparation of long-term antibacterial and antimildew coatings for leather but also has great application prospects in paper, clothing, furniture, and other fields, which has great significance in protecting consumers from the invasion of bacteria and mildew.

The purpose of the present work was to develop a fragrance encapsulation system using polyacrylate/paraffin microcapsules. The Polyacrylate/paraffin microcapsules were fabricated by the method of suspension polymerization in Pickering emulsion. Morphology, size distribution, and thermal resistance of polyacrylate/paraffin microcapsules were investigated by scanning electron microscopy, light scattering particle size analyzer, and thermogravimetric analyzer. Results indicated that the crosslinked PMMA/paraffin microcapsules and P(MMA-co-BMA)/paraffin microcapsules prepared under optimal conditions presented regular spherical shape and similar size distribution. The crosslinked P(MMA-co-BMA)/paraffin microcapsules exhibited better thermal stability, with a thermal resistance temperature up to 184 °C. Fragrance microcapsules were prepared by encapsulating fragrance into crosslinked P(MMA-co-BMA)/paraffin microcapsules. The prolonged release performance of fragrance microcapsules was measured by ultraviolet-visible near-infrared spectrophotometer. 63.9% fragrance was retained after exposing fragrance microcapsules in air for 3 months, and the fragrance continued to release over 96 h in surfactant solution (sodium lauryl sulfonate, 20 wt %). © 2016 Wiley Periodicals, Inc.

A key for the preparation of polyacrylate-based polyurethane is the synthesis of hydroxyl-terminated polyacrylate. To our knowledge, exactly one hydroxyl group of every polyacrylate chain has not been reported. The hydroxyl-terminated poly(butyl acrylate) (PBA) has been successfully synthesized by degenerative iodine transfer polymerization (DITP) of then-butyl acrylate (n-BA) using 4,4′-azobis(4-cyano-1-pentanol) (ACPO) and diiodoxylene (DIX) as initiator and chain transfer agent, respectively, and subsequently substituted reaction of the iodine-terminated PBA with β-mercaptoethanol in alkaline condition. The latter reaction was highly efficient, and the terminal iodine at the end of polymer chains were almost quantitatively transformed to a hydroxyl group. 2,2′-Azobis(isobutyronitrile) (AIBN) and ACPO were used as initiators in the DITPs ofn-BA. The results demonstrated that they had a significant influence on the terminal groups of the formed polymer chains. The structure, molecular weight, and molecular weight distribution of the hydroxyl-terminated PBA have been studied by1H,13C NMR, and GPC results. The components of hydroxyl-terminated PBA were determined by MALDI-TOF MS spectra, and their formation is discussed. The broad molecular weight distribution of the PBA and the difference in the polymerization behaviors from typical living radical polymerization are explained based on the results of1H NMR and MALDI-TOF MS spectra. The hydroxyl-terminated PBA has been successfully used in the preparation of PBA-based polyurethane dispersions (PUDs). The aqueous PUDs were stable, and based on the DSC results it can be said that the miscibility of hard segments with PBA chains was improved.Keywords:poly(n-butyl acrylate);degenerative iodine transfer;free-radical polymerization;waterborne polyurethane

With nano-ZnO, methyl methacrylate (MMA), ethyl acrylate (EA), and dodecafluoroheptyl methacrylate (DFMA) as reaction monomers, potassium persulfate as initiator, nano-ZnO/fluorine polyacrylate linen fabric finishing agent was prepared by semi-continuous seed emulsion polymerization to improve the hydrophobicity and anti-fouling performance of linen fabric. The structure and properties of the film and the finished fabric were characterized and analyzed by1HNMR, FT-IR, and TG. The results showed that the nano-ZnO/fluorine emulsion was successfully prepared with a particle size of about 46 nm, which was combined with linen. The contact angle of the finished linen fabric to water was 130.33°, which indicated that the finished linen fabric had good hydrophobicity. Meanwhile, the anti-fouling performance of the finished linen fabric was also improved. The introduction of nano-ZnO and organic fluorine in turn made linen fabric had the properties of the heat-resistant stability, UV resistance, antibacterial properties, and yellowing resistance.

Polyacrylate crude oil demulsifier is one of the hot topics in the research and development of demulsifier at present, there is a lack of systematic comparative study on performance and properties of polyether and polyacrylate crude oil demulsifier. In this paper, the demulsification performance and microscopic demulsification process of the two demulsifiers, namely polyacrylate P(MA-DBC) and polyether P199–59 are discussed. The demulsification performance of polyether P199–59 was superior to that of polyacrylate P(MA-DBC). The study of the microscopic process of demulsification established that for P199–59, the diffusion rate was faster, the saturated adsorption capacity was higher, the ability to destroy the oil-water interface film was stronger and the probability of water droplets collision coalescence was higher; therefore, it can achieve faster dehydration speed and higher dehydration rate than that of P(MA-DBC). The results of this comparative study are meaningful for improving the demulsification performance of polyacrylate demulsifier.

Moisture-sensitive materials need to meet the technical requirements of low power consumption, high precision and integratability, which are crucial for the development of new advanced moisture-sensitive devices and humidity sensor technologies. In this work, polyacrylates (PAC) were modified with nano halloysite powders (HNTs) to prepare resistive halloysite/polyacrylate composite moisture-sensitive films (PAC/HNTs) with excellent performances. Compared with the humidity-sensitive performance of PAC, the response time was reduced from 5 s to 0.9 s in the humidity range of 11–96% RH. Particularly, in the 30–96% RH humidity range, the average power consumption of the device was 88.41 μW and exhibited excellent linearity (R = −0.99), low wet hysteresis (5.04% RH), and excellent thermal and long-term stability. Thus, PAC/HNTs hold significant potential in the development of new humidity-sensitive devices and sensors with fast response, low power consumption, high accuracy and integratability.

The acetylene functional groups on polymer chains provide a photochemical access to modulate or actuate the properties of the polymer. We report here a photochemical way to actuate a polyacrylate to elastomers . High molecular weight acetylene functionalized homo- and copolymers of are prepared with a novel monomer , 2-(dimethylpropargyloxy)ethyl methacrylate , DMPOEMA, by photo-initiated free-radical polymerization (FRP) in solution at room temperature . The acetylene groups are tolerant of the solution photo FRP at 50 wt% concentration, but not tolerant to thermal FRP and photo FRP at 80 wt% concentration. Copolymers P(DMPOEMA- co -EA) with‾M n in 12,500–15,100 g/mol were prepared with conversion up to 90% at 50% concentration and three monomer feed ratios. The feed ratio of DMPOEMA had slight effects on the polymerization rate, but effects on PDI at higher monomer conversion with prolonged photo-irradiation. The acetylene functionalized polyacrylates become photo-sensitive and are photo cross-linkable or photo clickable after solvent is removed. Real-time FT-IR study reveals that the photo cross-linking with a tri-thiol compound follows the normal thiol-yne photochemistry , and the photo cross-linking catalyzed with only photoinitiator results in diene units in the cross-linked polymer networks . These photo-treated polyacrylate exhibited designable elastomer properties: with T g in −24 to −11 °C, more than 10 times increase of relative cross-linking density and resistant to solvents, improved stress, strain and elongation properties. This work paves a way for the acetylene functionalized (meth)acrylates as advanced photo-reactive material.

A series of novel polymeric form-stable phase change materials (FSPCMs) composed of poly(trimethylolpropane trimethacrylate-stearyl methacrylate) (PTS) and stearic acid were synthesized via solvent-free bulk polymerization. Stearic acid was used as phase change component, and PTS acted as supporting material. The chemical structure, crystalline properties, phase change ability, thermal reliability, and stability were characterized by Fourier transform infrared spectroscopy, X-ray diffraction (XRD), polarizing optical microscopy (POM), differential scanning calorimetry (DSC), accelerated thermal cycling testing, and thermogravimetric analysis (TG), respectively. The DSC results revealed that the maximum freezing and melting latent heat can reach 143.5 and 146.7 J g −1 . The POM and XRD results proved the existence of spherocrystal. Accelerating thermal test and TG demonstrated that FSPCMs had good reliability and stability in practical application. The prepared form-stable phase change materials with high enthalpy and proper phase change temperature have a promising prospect in thermal energy storage.

In this study, 2-(perfluorohexyl)ethyl methacrylate, hydroxyethyl methacrylate and methyl methacrylate were used to synthesize three random fluorinated polyacrylates with various fluorine contents ( i.e. , F1H1, F3H1, and F5H1) and one block fluorinated polyacrylate ( i.e. , PFPHM) through traditional radical polymerization and atom transfer radical polymerization, respectively. These copolymers were further adopted as hydrophobic additives to incorporate into 2K polyurethane (PU) clearcoats. Effect of the type and dosage of the fluorinated polyacrylate on the haze, surface hydrophobicity, outdoor hydrophobicity durability and dirt pick-up resistance (DPUR) of modified coatings were investigated. Fluorinated polyacrylate additive with higher fluorine content is easier to cause haze of 2K PU clearcoats, nevertheless, hydrophobic surface could be acquired at lower dosage, alleviating its negative effect on transparency. PFPHM showed extremely higher hydrophobicity modification efficiency compared to the random polyacrylate additive, due to its easy enrichment at the superficial layer of 2K PU clearcoats. Moreover, PFPHM-modified 2K PU coatings presented the best hydrophobicity durability and dirt pick-up resistance in outdoor exposure test. The loss of hydrophobicity outdoors was mainly due to the aging of PU matrix, loss of fluoroalkyl chains, and partially to the dirt adhesion.

Snus is one of the types of smokeless tobaccos, which is popular in many countries and regions. The nicotine level in the plasma samples obtained from snus users is similar to the nicotine level obtained from cigarette smokers; hence, the snus users find it difficult to quit. The aim of this study is to develop new semi-interpenetrating polymer (SIPN) membranes that control the stable release of nicotine from snus, achieving the purpose of quitting smoking. Here, the SIPN comprising a polyacrylate network and PEG chains was synthesized through in situ radical polymerization. The SIPN was characterized by Fourier transform infrared spectroscopy, contact angle, differential scanning calorimetry, scanning electron microscopy, cytotoxicity, and in vitro release experiments. Furthermore, this SIPN was used to evaluate the release properties of nicotine in different snus samples varying in moisture, pH, and the tobacco’s particle size. The results indicated that the new SIPN could control release of nicotine at a specific rate, and the release rate could be adjusted according to the customer requirements. Thus, the new SIPN was contributed to build a new nicotine replacement therapy that served the snus users.

Polyacrylate was widely used in textiles, leather, and functional coatings due to its excellent film formation and flexibility. However, its durability was compromised by mechanical damage and poor water resistance. This study aimed to design a UV-induced self-healing polyacrylate coating (PXD) using vinyl-modified coumarin and acrylate monomers based on photoreversible covalent and hydrophobic interactions. The effect of the coumarin structure on the mechanical and self-healing properties was systematically examined. Results showed that increasing polymer chain flexibility, extending the distance between coumarin structures and the main chain, and raising the healing temperature enhanced self-healing efficiency. The PXD samples achieved over 84% healing efficiency after 8 h of 365 nm UV irradiation at 60°C, with scratches approximately 15 μm wide nearly fully healed within 2 h. Molecular dynamics simulations confirmed the influence of monomer structure on polymer flexibility, and the PXD self-healing mechanism was clarified. PXD-5 also exhibited improved hydrophobicity and water resistance, particularly under UV light, significantly enhancing leather durability. This development of UV-induced self-healing polyacrylate coatings represents a significant advancement in functional coating materials.

Composite coatings enhance fabrics with properties like conductivity, flame resistance, and water repellency. However, these coatings can suffer damage and cracking during processing and use, which compromises their mechanical performance and lifespan. Herein, this study involves the synthesis of polyacrylic resin using various monomers, including methyl methacrylate, perfluorodecyl acrylate, and hydroxyethyl acrylate, through radical polymerization. Simultaneously, amino silicone oil and polyacrylic resin are covalently bonded to form silicone-modified polyacrylic resin. When mixed with amino-functionalized carbon nanotubes, a flexible conductive coating is produced on the fabric surface, enhancing mechanical properties such as strength and ductility. The fabric coating also exhibits excellent self-healing properties due to the formation of multiple hydrogen bonds between the amino groups on the carbon nanotubes and the polyacrylic resin macromolecules. Furthermore, the resulting fabric coating demonstrates hydrophobicity and sensing characteristics suitable for wearable sensor applications, which can be applied in monitoring standard movements in table tennis.
