ZrO 2 is widely used. However, surface hydrophilicity is harmful to waterproof devices. In this work, epoxy-based polyhedral oligomeric silsesquioxane (POSS) was chemically bonded to ZrO 2 sheet surface for weather-resistant hydrophobicity and anti-adherence property. First, ZrO 2 sheet was modified with hydroxyls, followed by amino modification. Then, surface POSS modification was performed via ring-opening addition. Next, composition and micro-morphology of POSS-treated sheet were clarified. Ultimately, the dependence of water contact angle of POSS-modified sheet on POSS solution treating time was researched, and the highest contact angle of 132.6° was gained by 24-h treating. Acid corrosion, alkali corrosion, and ultraviolet radiation for 48 h were employed to verify good weather resistance with contact angles over 120°. POSS-modified sheet had good anti-adherence capacity. Cooperation of POSS and ZrO 2 was utilized to obtain low surface energy and high surface roughness. This work might help to obtain hydrophobic ceramics as catalyst supports for oil-phase reactions.

In this study, a novel amino acid and ionic liquid dual organically functionalized reagents modified polyhedral oligomeric silsesquioxane methacryl substituted (POSS-MA) based hybrid monolithic column (POSS-VBI-Cys) was designed and reported. With amino acid L-cysteine and ionic liquid 1-vinyl-3-butylimidazolium bromide as dual monomers, POSS-MA as the crosslinker, the new POSS-VBI-Cys hybrid monolithic column could be facilely fabricated via the “one-pot” free radical copolymerization and thiol-ene click reaction. Because of the introduction of polar amino acid L-cysteine, the new POSS-VBI-Cys column exhibited attenuated hydrophobicity in reversed-phase liquid chromatography separation. Polar amides, nucleosides and nucleic acid bases displayed strong retention on the POSS-VBI-Cys column and could be successfully separated. Furthermore, the new POSS-VBI-Cys column displayed good separation selectivity for model glycoproteins and non-glycoproteins mixture and it was also successfully used for the purification and separation of TARG1 protein from its originally expressed sample. In the future research, we will further exploit its performances for separation of intact proteins and in-depth proteome applications.

In this study, epoxidized soybean oil was modified to prepare acrylated epoxidized soybean oil (AESO) and vinyl/acrylate ended soybean oil (VASO), which were blended with mercaptopropyl polyhedral oligomericsilsequioxane (POSS-SH) to prepare UV curable thiol-acrylate and thiol-ene-acrylate hybrid coatings. Photopolymerization processes of the coatings were measured and the results showed that addition of POSS-SH obviously increased the conversion of double bond. The physical and mechanical properties of all cured samples were investigated, which indicated that the pencil hardness, tensile strength, and fracture toughness were significantly improved by POSS-SH. Moreover, with increasing POSS-SH content, the water contact angles of cured samples were increased, and the water resistance was greatly improved. © 2015 Wiley Periodicals, Inc. J. Appl. Polym.

Materials hybrided by organic and inorganic partners via chemical bonds formation are able to display stable and multi-functional behaviors. Then, the versatile sensing platform could be established depending on their specific chemical and physical properties. In this research paper, we prepared the fluorescence materials (POSS-PDB and POSS-NTB) by a simple method. Among of them, POSS-NTB was verified as a mesoporous material with a narrowed pore diameter around 17 nm and the large Brunauer-Emmett-Teller (BET) surface area of 227 m 2 /g. Then, the solid powder of POSS-NTB was selected and evidenced as effective gas sensor toward CO 2 , N 2 and O 2 at 273 K under 1 atm pressure. Additionally, these fluorescence materials could be successfully applied as a pH sensor in the solution phase. Through combining biocompatible POSS and fluorescent molecules, POSS-NTB could enter into the cells and aggregate in the cytoplasm successfully.

In this work, two silicon nanomaterials are doped into polymer/liquid crystal composites by a facile method. SEM and FT-IR characterizations indicate that SiO 2 -SH and synthesized thiol polyhedral oligomeric silsesquioxane (POSS-SH) have been successfully implanted into PDLCs successfully. The electro-optical tests imply that the electro-optical performance of PDLC films can be greatly enhanced by doping proper amounts of SiO 2 -SH nanoparticles and nanostructured POSS-SH into the polymer matrix . The driving voltage can be reduced by nearly 78.2% if the concentration of SiO 2 -SH is 4 wt%; whereas only nearly 60% driving voltage is reduced when 4 wt% POSS-SH is doped into system, indicating better electric-optical performance regulation effect of SiO 2 . The lower driving voltage of SiO 2 -SH doped PDLC samples may be due to the existence of high content –SH on the surface of nanoparticles, which can conduct click reactions with acrylate bond under the effect of initiator.

Gypsum is an environmentally friendly, healthy, and low-cost building material. However, its poor water resistance significantly limits its application in the construction field. In this study, octa(heptadecafluorodecyl) polyhedral oligomeric silsesquioxane (F-POSS) is synthesized as a hydrophobic agent and applied to gypsum-based flat panels via a simple brush-coating process to construct a hydrophobic coating. The microstructure, water contact angle, and abrasion resistance of the resulting hydrophobic coating on gypsum substrates are systematically characterized. The results show that, compared with the unmodified gypsum board (CA = 85.27°), the hydrophobicity of the gypsum substrate is significantly improved after surface modification, with the contact angle increasing to 135.8°. Notably, after abrasion testing, the hydrophobicity does not deteriorate but instead increases by 7.2%, reaching a contact angle of 145.67°. To further elucidate the underlying mechanism, 3D surface profilometry is employed to characterize the surface roughness and topographical complexity of the gypsum boards before and after hydrophobic modification. These results demonstrate that the prepared hydrophobic material exhibits promising application potential for enhancing the water resistance of gypsum-based materials.

Multifunctional protective textiles that resist fire, suppress bacterial contamination, and enable the conversion of chemical warfare agent simulants are highly desirable for harsh operational environments. Herein, a hybrid coating was constructed on cotton, polyester (PET), and polyester/cotton blended fabrics (T/C) using a two-step hot-pressing route. A Zn-based dual-ligand metal organic framework (MOF) layer was first grown in situ to provide flame-retardant catalysis and antibacterial Zn 2+ activity, followed by the introduction of amino-functionalized polyhedral oligomeric silsesquioxane (POSS) and immobilization of Tetrakis (4-carboxyphenyl) porphyrin (TCPP) through interfacial interactions to form a robust hybrid network. The resulting fabrics showed substantially improved flame-retardant performance, with the limiting oxygen index (LOI) of cotton increasing from 17.7% to 44.8%, together with high char yield. They also exhibited broad-spectrum antibacterial activity, with more than 99.9% inhibition against Staphylococcus aureus and Escherichia coli , and enabled light-driven degradation of chemical warfare agents (2-chloroethyl ethyl sulfide, CEES), achieving approximately 95% conversion within 10 min. In addition, all coated fabrics retained more than 90% of their initial LOI values after 30 laundering cycles, indicating good laundering resistance of the flame-retardant performance. This work offers a scalable strategy for integrated multifunctional protective textiles.

A novel amphiphilic diblock copolymer, PHEMAPOSS-b-P(DMAEMA-co-CMA), was prepared via reversible addition–fragmentation chain transfer (RAFT) polymerization, where PHEMAPOSS block was first synthesized using a methacrylate monomer based on polyhedral oligomeric silsesquioxane (HEMAPOSS), and PHEMAPOSS was further utilized to prepare the block copolymer via RAFT copolymerization of 2-(dimethylamino)ethyl methacrylate (DMAEMA) and reduction-cleavable coumarin methacrylate (CMA) monomer. PHEMAPOSS-b-P(DMAEMA-co-CMA) could self-assemble in water to form spherical micelles with POSS core and stimuli-responsive shell. The micelles were cross-linked by photodimerization of coumarin, and then hollow polymeric capsules could be finally obtained via etching the POSS core in the solution of hydrofluoric acid (HF). The morphologies of the micelles and hollow polymeric capsules were well characterized by TEM, SEM, and DLS. The hollow polymeric capsules are responsive to typical physiological stimuli such as pH, and redox potential, and could be further utilized in the encapsulation and release of tetraphenylporphyrin tetrasulfonic acid hydrate (TPPS) for photodynamic therapy (PDT). The in vitro release of TPPS-loaded polymeric capsules allowed a relatively low TPPS release at pH = 7.4. However, a burst release of TPPS was observed in the presence of 10 mM glutathione (GSH) at pH = 5.5. Confocal laser scanning microscopy (CLSM) confirmed that TPPS-loaded polymeric capsules could well improve the internalization rate in MCF-7 cells. According to the result of MTT assay, TPPS-loaded polymeric capsules demonstrated efficient PDT efficacy and low dark toxicity toward MCF-7 cells. Thus, TPPS-loaded polymeric capsules have presented potential application in PDT.

Ionic liquids-based solid polymer electrolytes enhance the battery’s overall performance without drawbacks in safety compared with conventional electrolyte. In order to develop a novel solid electrolyte, we synthesized a series of novel room temperature imidazolium-based polyhedral oligomeric silsesquioxane ionic liquids (POSS-ILs) consisting of POSS-COO − anions and a variety of imidazolium cations, which will be used as plasticizers of solid polymer electrolyte in this work. The thermal stabilities of POSS-ILs have been dramatically enhanced by the introduction of POSS moiety, and the initial decomposition temperatures of POSS-ILs have increased by at least 94 °C compared to their corresponded succinamic acid ionic liquids. The glass transition temperatures of POSS-ILs also have increased to − 15.9 to − 25.4 °C. Then the POSS-ILs are employed to obtain a novel solid polymer electrolyte based on blend of polyethylene oxide, poly(vinylidene fluoride-hexafluoropropylene), propylene carbonate and lithium bis(trifluoromethanesulfonyl) imide with high ionic conductivity and electrochemical windows. The ionic conductivities of POSS-ILs-based solid polymer electrolytes are up to 8.0 × 10 −4 S cm −1 at 22 °C and 2.0 × 10 −3 S cm −1 at 62 °C, and the electrochemical windows of POSS-ILs-based solid polymer electrolytes are stable up to 5.0 V. Moreover, the Li/LiFePO 4 cell containing POSS-ILs-based solid polymer electrolytes exhibits good cycling performance and high rate stability. These results suggest that the POSS-ILs-based solid polymer electrolytes could be a suitable prospective electrolyte material for lithium-ion battery applications.

The toughening of epoxy resin has always been one of the key topics in the researches about high-performance matrix used for advanced composites. Up to now, single-property enhancement is usually accompanied by some compromises of other properties. This work constructed a novel in-situ interpenetrating network (IPN) structure composed of epoxy resin and vinyl ester resin (VER), along with modified octavinyl polyhedral oligomeric silsesquioxane (EPOSS) as the toughening core. In the present resin system, the VER component was firstly introduced to form IPN structures without phase separation to bring the improvement of overall strength and plastic deformation capacity. Moreover, the EPOSS could realize nano-scale dispersion in the resin matrix through the chemical reactions, which acted as the trigger of plastic shear deformation toughening under particle debonding. The side chains' physical entanglement of EPOSS played the key role in maintaining a balance between toughness and mechanical strength. With only 2 wt% of EPOSS, the optimal increase in impact toughness reached 139.6%, in addition to the 17.9% improvement of tensile strength and 9.0% enhancement of Young's modulus .

Triphenylamine functionalized polyhedral oligomeric silsesquioxane (POSS@TPA) was prepared using the Friedel-Crafts reaction with tris(4-bromophenyl)amine (TPA) as the functional monomer and polyhedral oligomeric silsesquioxane (POSS) as the framework. The as-prepared POSS@TPA has a stable structure and accomplished pore performance, allowing for the selective adsorption of Sudan I and result in the fluorescence quenches of POSS@TPA. Thus, the POSS@TPA could be used as sensors to fluorescence detect 0.12–7.4 mg/L Sudan I, with a detection limit of 0.091 mg/L. Moreover, the POSS@TPA have good reuseability can be reused more than 5 cycles after washing. Noteworthily, the response time of POSS@TPA for determination was as short as 1 min. Furthermore, the sensor was effectively used to determine Sudan I in cakes with excellent recoveries (86.4–108.8 %) and relative standard deviations (2.5–4.9 %). The results matched those of high-performance liquid chromatography (HPLC). Our work shows great potential in terms of the rapid detection of food safety.

Hybrid monolithic stationary phase based HPLC is a typical example of practices in separation science. In this study, we developed a dual polyhedral oligomeric silsesquioxanes (POSS) polymerization approach to the preparation of a hybrid monolithic stationary phase of tri-porous structure and various surface chemistry. N-phenylaminopropyl-POSS (PA-POSS) and glycidyl-POSS (EP-POSS) were exemplified to demonstrate effective mutually-mediated separation mechanisms of the hybrid monolithic stationary phase and mobile phase towards diverse small molecules. PA-POSS and EP-POSS can be the monomer and/or crosslinker each other. They were polymerized via the epoxy-ring opening reaction to form the poly[(PA-POSS)-(EP-POSS)] (polyPOSS) monolithic stationary phase of 110.6/164.6 Å 3 micropore (as a cube/ball), 10 nm mesopore and 0.95 μm macropore with the native siloxane cage and remaining phenyl/epoxy as well as chemically generated positive-chargeable tertiary phenylamine and hydrophilic hydroxyl groups. Such pore-structure and surface chemistry allow us to perform the effective separation of targeted small molecules, such as alkylbenzenes and alkylbenzene ketones, nucleic acid bases and amino acids, as well as phenols and phenolic acids, under reversed-phase, HILIC and mixed mode (polarity, size-exclusion and hydrogen-bonding) by just changing the molar ratio of POSS-precursors, and the composition and pH of a mobile phase as well. We believe that the approach developed herein can be extended to fabricate other kinds of hybrid monolithic stationary phases that are suitable for the separation of biomacromolecules and chiral molecules when choosing the existed POSS and/or designing new POSS with the substituted pendant groups of different physicochemical properties.
