Facile synthesis of silica-polymer hybrids via simultaneous RAFT process and hydroxyl-alkoxysilane coupling reaction
This study aimed at synthesis of silica particles grafted with better-defined homopolymers and block copolymers by tandem approach. Z-functionalized S-benzyl S’- (3-trimethoxysilyl)propyltrithiocarbonate (BTPT) was used as a couplable RAFT agent to synthesize the target inorganic-organic hybrids. Simultaneous coupling reaction and RAFT process using silica particles and BTPT as raw materials...

Facile synthesis of highly pure block copolymers by combination of RAFT polymerization, click reaction and de-grafting process
pubs.rsc.org/en/content/articlelanding/2012/py/c1py00396h A facile strategy to synthesize highly pure block copolymers with polymeric segments such as polystyrene, polyacrylamides and polyacrylates was described. The methodology involves grafting reaction by tandem RAFT polymerization and azide-alkyne cycloaddition reaction and a subsequent de-grafting reaction via aminolysis or radical-induced a...

Gold Nanoparticle/Polypyrrole Bi-layer Film Formed through a Solution-Based Seeding Growth Process
Gold nanoparticles (NPs)/polypyrrole (PPy) bi-layer film was fabricated through a solution-based seeding process. The growth of the gold layer has been studied by the use of a field emission scanning electron microscope and UV–vis spectroscope. The results demonstrated that the PPy chains served as the reductant of chloroauric acid and the ligands to stabilize gold NPs. The resulting gold/PP...

Fabrication of Robust Micro-patterned Polymeric Films via Static Breath Figure Process and Vulcanization
Here, we present the preparation of thermally stable and solvent resistant micro-patterned polymeric ?lms via static breath-?gure process and sequent vulcanization, with a commercially available triblock polymer, polystyrene-b-polyisoprene-b-polystyrene (SIS). The vulcanized honeycomb structured SIS ?lms became self-supported and resistant to a wide range of organic solvents and thermally stable u...

27. Process and mechanism of phase separation in polymer mixtures with a thermotropic liquid crystalline copolyester as one component
The phase separation and the coarsening process of polymer mixtures with a thermotropic liquid crystalline polymer (LCP) as one component are investigated. The LCP used is a main-chain type copolyester X-7G, comprised of p-hydroxybenzoic acid (60 mol %) and ethylene terephthalate (40 mol %) units. The isotropic, transparent, and homogeneous test specimens of the 50/50 mixtures of X-7G and po...
