Membrane of Poly(vinyl butyral) (PVB) or cationic PVB (CPVB) blended with Poly(Vinylidene Fluoride) (PVDF) Prepared by a Nonsolvent induced phase separation method: miscibility and hydrophilicity
The synthesized hydrophilic polymers [poly (vinyl butyral) (PVB) and cationic PVB (CPVB)] blended with poly (vinylidene fluoride) (PVDF) were used to fabricate hydrophilic ultrafiltration membranes. A visual inspection method and a glass transition temperature method were applied to study the miscibility of PVDF/PVB and PVDF/CPVB blend systems. The results showed that the PVDF/PVB was an immiscibl...

Highly compatible acid-base blend membranes based on sulfonated poly(ether ether ketone) and poly(ether ether ketone-alt-benzimidazole) for fuel cells application
Miscible acid-base blend membranes were developed by incorporating poly(ether ether ketone-alt-benzimidazole) (PEEK-alt-BI) into highly sulfonated poly(ether ether ketone) (SPEEK). The blend membranes with PEEK-alt-BI content up to 20 wt% via optical observation were transparent, indicating an excellent miscibility between the two components. This was further verified by a well-defined morphology ...

【Mater Sci Eng C】Preparation of poly(cyclooctene)-g-poly(ethylene glycol) (PCOE-g-PEG) graft copolymers with tunable PEG side chains via ROMP and its protein adsorption and platelet adhesion properties
In our previous work [H. Shi, D. Shi et al., Polymer Chemistry 2(2011)679–684], polycyclooctene-g-PEG (PCOE-g-PEG) copolymers were synthesized via ring opening metathesis polymerization (ROMP) from PEG functionalized cyclic olefin macromonomers and cyclooctene. The grafting degree and the grafting site were easily controlled through the “grafting through” approach. The PCOE-g-PEG film surface w...

A specially structured conductive nickel-deposited poly(ethylene terephthalate) nonwoven membrane intertwined with microbial pili-like poly(vinyl alcohol-co-ethylene) nanofibers and its application for alcohol sensor
The trend in development of portable and wearable sensors in
healthcare-related applications promotes an expanding demand for flexible,
stretchable and electrically conductive fabrics. A novel structured conductive
nickel-deposited poly(ethylene terephthalate) (PET) membrane intertwined with
microbial pili-like poly(vinyl alcohol-co-ethylene) (PVA-co-PE) nanofibers has been
prepared. FTIR and XRD ...

Reduction-Responsive Disassemblable Core-Cross-Linked Micelles Based on Poly(ethylene glycol)-b-poly(N-2-hydroxypropyl methacrylamide)–Lipoic Acid Conjugates for Triggered Intracellular Anticancer Drug Release
Reduction-sensitive reversibly core-cross-linked micelles were developed based on poly(ethylene glycol)-b-poly(N-2-hydroxypropyl methacrylamide)–lipoic acid (PEG-b-PHPMA-LA) conjugates and investigated for triggered doxorubicin (DOX) release. Water-soluble PEG-b-PHPMA block copolymers were obtained with Mn,PEG of 5.0 kg/mol and Mn,HPMA varying from 1.7 and 4.1 to 7.0 kg/mol by reversible add...

106. Nanostructures and Surface Hydrophobilicity of Self-assembled Thermosets involving Epoxy Resin and Poly(2,2,2-trifluoroethyl acrylate)-block-poly(ethylene oxide) Amphiphilic Diblock Copolymer. F.P.Yi, S.X.Zheng, T.X.Liu. J. Phys. Chem. B, 113(7), 1857-1868, 2009.
Poly(2,2,2-trifluoroethyl acrylate)-block-poly(ethylene oxide) (PTFEA-b-PEO) amphiphilic diblock copolymer was synthesized via the reversible addition-fragmentation transfer polymerization of 2,2,2-triffluroethyl acrylate with dithiobenzoyl-terminated poly(ethylene oxide) as a chain-transfer agent. The amphiphilic diblock copolymer was incorporated into epoxy resin to prepare the nanostructured ep...
