Fast development of oil industry and cargo distribution make accidental oil spills more possible in the course of transportation. Here we fabricated a hydrophobic macroporous phenol resin poly high internal phase emulsions (poly-HIPEs) to adsorb oil pollution. To improve hydrophobic property and adsorption ability of the poly-HIPEs, we adopted a facile way to modify the poly-HIPEs that Fe 3 O 4 nanoparticles act as magnetic particles to make the poly-HIPEs magnetic and 1-dodecanethiol as hydrophobic monomer grafted to the surface to strengthen the hydrophobicity with dopamine as the adhesive. As a result, we succeed in making the poly-HIPEs superhydrophobic and their contact angle transforms from 107° to 150°. After the oil adsorption experiment, the adsorption capacity of the modified poly-HIPEs is obviously better than the original poly-HIPEs which is about ten times than original weight of material, what's more, the final products also have good recycle ability after ten times' employing, which makes it a promising candidate material for use in oil-spill cleanups. © 2017 Wiley Periodicals, Inc.

A novel TiO 2 hydrogel cage model was built for the removal of methylene blue (MB), an organic pollutant. This TiO 2 hydrogel cage was prepared with the biomass materials of hydroxyethyl cellulose (HEC) and carboxymethyl cellulose (CMC), and this hydrogel cage structure was characterized by scanning electron microscopy, transmission electron microscopy, and X-ray diffraction. The contents of the encased TiO 2 and its swelling properties with different CMC proportions of this hydrogel cage were studied to obtain a suitable crosslinking network structure and optimal synthesis conditions. Compared to an equivalent amount of pure TiO 2 , the much higher removal efficiency of MB with our prepared TiO 2 hydrogel cage was attributed to the synergistic effect of the photocatalytic degradation for TiO 2 and the adsorption enrichment for cellulose hydrogels. Furthermore, the adsorption kinetics of the intraparticle diffusion model were used to study the adsorption enrichment process of the TiO 2 hydrogel cage. In addition, on the basis of the results of photocatalytic degradation and recycling experiments, excellent performances with respect to self-cleaning, regenerative ability, and easy recovery, were shown for this HEC–TiO 2 –CMC cage material, which demonstrated ideal application potential for MB removal. © 2017 Wiley Periodicals, Inc.

In recent years, the using of reproducible resource and economical and efficient synthesis method has got wide concern. Herein, an environmental-friendly plasticizer originated from cardanol was synthesized by click chemistry. First, the cardanol sulfide (CS) was obtained by click chemistry reaction between the double bond of the side chain of cardanol and mercaptoethanol. The degree of the click reaction was estimated to reach 84.7% by testing the content of sulfur. Then, the epoxidation of the hydroxyl was performed to get cardanol based epoxy plasticizer (CEP) in the presence of epichlorohydrin. The epoxy value was 0.32. The structure of CS and CEP was confirmed by FT-IR and NMR techniques. A Haake torque rheometer was used to research the action of CEP on polyvinyl chloride (PVC). Results showed that it possessed favorable plasticization effect and stabilization effect on PVC. CEP had good heat stabilization in PVC, and could decrease the T g of PVC significantly. Moreover, CEP could increase the tensile strength of PVC when in a small amount, and could increase the plasticity of PVC when in a larger quantity significantly. The characteristics of volatile, migration and solvent extraction of PVC plasticized by CEP is similar to by dioctyl phthalate (DOP). © 2017 Wiley Periodicals, Inc. J. Appl. Polym.

Due to low thermal stability, poor migration, and extraction resistances, the antioxidant with low molecular weight is easy to physically lose during processing and long-term service, and its applications are severely restricted. To increase the molecular weight of antioxidant is one of the promising methods to overcome such drawbacks. In this study, the extraction resistance of a macromolecular antioxidant, namely polyhydroxylated polybutadiene containing thioether binding 2,2′-thiobis(4-methyl-6- tert -butylphenol) (PHPBT- b -TPH), was investigated by extraction resistance test and equilibrium swelling experiment. The results exhibited that the PHPBT- b -TPH offered much better extraction resistance in natural rubber (NR) than the low molecular weight antioxidant TPH. In addition, the extraction resistance of hydroxyl-terminated polybutadiene (HTPB), polyethylene glycol (PEG), and polypropylene glycol (PPG) in NR were also compared to study the extraction mechanism of the PHPBT- b -TPH. It was found that the higher molecular weight of PHPBT- b -TPH and the co-vulcanization between PHPBT- b -TPH and NR were the main reasons for the excellent extraction resistance. © 2017 Wiley Periodicals, Inc.

Fluorinated acrylate emulsions have been extensively applied for hydrophobic surface coatings. To obtain fluorinated emulsions of low surface energy, amphiphilic sulfonyl macro emulsifiers consisting of 2-(perfluorohexyl) ethyl acrylate (PFHEA) and 2-acrylanmido-2-methylpropanesulfonic acid (AMPS) were designed via radical polymerization and subsequently used for the emulsion copolymerization of PFHEA, methyl methacrylate (MMA), and methyl butyl acrylate (MBA). Under optimum synthesis conditions, the emulsifier displayed superior emulsification properties such as high monomer conversion, small particle size, and excellent stability compared with conventional emulsifiers. The corresponding emulsions with sulfonyl macro emulsifiers exhibited extreme low surface energy (9.8 mN/m) and outstanding hydrophobicity due to high contents of fluorinated chains, as well as thimbleful hydrophilic sulfonyl groups, which shows the great potential in water repellent modification application. © 2017 Wiley Periodicals, Inc.

In this study “core-shell” structure of carbon nanotube (CNT) nanocapsules, which aimed at toughening poly(lactic acid) (PLA) were designed by a synthetic strategy consisting of two reaction steps. The first step was to produce reactive chemical bond to bridge CNTs and PLA. So coupling agent KH570 was used to modify CNTs (CNTs-KH570). The second step involved ring open polymerization of lactide (LA). Lactide polymerized into PLA under catalysis and meanwhile grafted onto CNTs via KH570 (CNTs-KH570-PLA). Thus, the CNTs nanocapsules were constructed. Fourier transform infrared spectroscopy (FTIR) showed coupling agent KH570 succeeded in linking CNTs and PLA during LA polymerization. In addition, scanning electron microscopy (SEM) and transmission electron microscope (TEM) indicated CNTs dispersed homogeneous in PLA matrix and the compatibility between them was excellent. The mechanical test also suggested the designed nanocapsules had good effect on toughening PLA composites. This research found one economical and simple way to improve PLA mechanical properties and further broaden its application in many fields. © 2017 Wiley Periodicals, Inc. J. Appl. Polym.

Polyacrylamide- b -poly(methacrylic acid) was prepared on the surface of Au electrode (Au/PAM/PMAA) for Pb 2+ ion electrochemical sensing via metal-free visible-light-induced atom transfer radical polymerization, which was very simple, convenient, and environmentally friendly. Au/PAM/PMAA was carefully examined by cyclic voltammetry, electrochemical impedance spectroscopy, and X-ray photoelectron spectroscopy. Further, Au/PAM/PMAA was successfully used for the determination of Pb 2+ ion by differential pulse anodic stripping voltammetry. Under the optimal conditions, a linear response from 1.0 × 10 −11 to 1.0 × 10 −4 mol/L with detection limit of 2.5 × 10 −12 mol/L ( S / N = 3) was achieved from the results of experiments. Comparing with similar Pb 2+ sensors, the broader linear range and lower detection limit suggested the promising prospect of Au/PAM/PMAA. In a word, the work of this article had an important significance for the polymer-modified electrodes and the sensitive detection of Pb 2+ . © 2017 Wiley Periodicals, Inc. J. Appl. Polym.

A facile method is developed to synthesize silicone-toughened unsaturated polyester (SUP-M) by monomer copolymerization of anhydrides and diols with hydroxyl-terminated silicone. The structures and molecular weights of the SUP-M resins were characterized by Fourier transform infrared spectroscopy and gel permeation chromatography, respectively. The gelation time and mechanical properties, including impact strength, flexural strength, and tensile strength, were investigated. The fracture behaviors were studied by scanning electron microscopy, and their glass-transition temperature and storage modulus were measured by dynamic mechanical analysis. The experimental results showed that the impact strength of SUP-M can be obviously improved through copolymerization with a small amount of silicone without decreasing its mechanical properties. The impact strength, flexural strength, and tensile strength of SUP-M-0.5 are as high as 12.5 KJ m −2 , 131 MPa, and 59 MPa, which are increased by 76.1%, 21.2%, and 6.7%, respectively, compared with those of unsaturated polyester. Impacts on SUP-M with low silicone content produce a large number of evenly and regularly distributed continuous narrow crack bands combined with many evenly distributed branching crazes, which are of great benefit in absorbing a large amount of impact energy. © 2017 Wiley Periodicals, Inc.

A series of thermal insulation, acoustic absorption isocyanate-based lightweight polyimide (PI) foams with 4,4′-diaminodiphenyl ether (ODA) units were prepared from polyaryl polymethylene isocyanate (PAPI) and the esterification solution derived from pyromellitic dianhydride (PMDA) and ODA. The structures and properties of the PI foams prepared with different molar ratio of ODA/PMDA were investigated in detail. The results show that the ODA units have great influence on the foam properties. With the increase of the ODA units, the density decreases firstly and then increases. When the molar ratio of ODA/PMDA is 3/10, the foam reaches the minimum density (13.7 kg/m 3 ). Moreover, with increasing the ODA units, the acoustic absorption properties increase firstly and then decrease owing to the variation of the average cell diameter of the PI foams. All PI foams show excellent thermal stability, and the 5% and 10% weight loss temperature are in the range of 250–270 °C and 295–310 °C, respectively. In addition, the PI foams present low thermal conductivity and thermal diffusivity. Furthermore, the mechanical property was also evaluated and the compressive strength of the PI foams is in the range of 33.0–45.7 kPa. © 2017 Wiley Periodicals, Inc. J. Appl. Polym.

A (meth)acrylate copolymer grafted with long fluorinated side chains (AGLF) was synthesized successfully through a two-step procedure. First, a carboxyl terminated fluoropolymer, poly(2,2,3,4,4,4-hexafluorobutyl methacrylate) was synthesized by conventional radical polymerization in the presence of 3-mercaptopropionic acid as chain transfer agent. And then the fluoropolymer was grafted to the in-house synthesized polyacrylate (MMA -r- BA -r- GMA). Fourier transform infrared spectroscopy and 1 H-nuclear magnetic resonance spectroscopy were employed to verify the synthesis of AGLF. Moreover, the surface properties were investigated by contact angle measurement and X-ray photoelectron spectroscopy. The results proved that a small amount of poly(2,2,3,4,4,4-hexafluorobutyl methacrylate) addition can create a hydrophobic surface effectively. Furthermore, the X-ray photoelectron spectroscopy results showed that it is the AGLF grafted with longer fluorinated side chain that have more fluorine atoms enriched on the surface and thus performed better hydrophobicity and lipophobicity. Testified by thermogravimetric analysis and differential scanning calorimetry, it was found that AGLF films have excellent thermal properties. © 2017 Wiley Periodicals, Inc. J. Appl. Polym.

The accumulation of dissolved and colloidal substances (DCS) and inorganic salts in the white water of papermaking circulation system will result in the abnormal runnability of paper machine and low quality of products. Contaminant adsorption on a solid adsorbent in a fluidized bed reactor has been applied for white water treatment. In this study, three kinds of hydrophilic polymers {i.e., poly[methacryloxyethyltrimethyl ammonium chloride] (poly-MAC), polyacrylamide, and poly[acrylic acid] (poly-AA)} had been grafted on the surface of the polystyrene (PS) spheres through two-step reactions. Fourier transform infrared spectroscopy, scanning electron microscopy, elemental analysis, Zeta potential were evaluated the characteristics of modified PS spheres. The results showed that PS-poly(MAC) had good affinity to DCS. Cationic demand, total DCS, and turbidity of white water had been reduced by 79.5%, 40.0%, and 38.4%, respectively, when the amount of PS-poly(MAC) was 50 g/L. While PS-poly(AA) played an important role in removal of metal ions so as to cut down the conductivity of white water. © 2017 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2017 , 134 , 45169.

Poly(methyl methacrylate) grafted silica (SiO 2 -g-PMMA) was synthesized via in situ suspension polymerization. To achieve better uniform dispersion, hexadecyltrimethylammonium bromide (CTAB) was introduced into xylene to manipulate SiO 2 aggregation. SiO 2 -g-PMMA or SiO 2 was incorporated into PMMA matrix by in situ polymerization to prepare PMMA-based nanocomposites. The effect of CTAB amount, in the range 0–35 wt %, on the modification was evaluated by DLS, TGA, and FTIR. Furthermore, morphology, optical, mechanical, and thermal properties of PMMA nanocomposites was characterized by SEM, UV–vis, DMA, and TGA. Owing to surface functionalization, SiO 2 -g-PMMA exhibited far more excellent compatibility and dispersion in matrix compared with SiO 2 . Surface hardness and thermal properties of nanocomposites were enhanced significantly under the premise in high transparency. It is expected that transparent nanocomposites with promising scratch-resistance could have wide applications, such as airplane shielding window and daily furniture. © 2016 Wiley Periodicals, Inc. J.
