Photo-induced dynamic association of coumarin pendants within amphiphilic random copolymer micelles
关键字:Photo-induced,amphiphilic random copolymer micelles
The water-soluble amphiphilic random copolymer of P(DMA-co-VBC) with coumarin pendants has been designed to investigate the photo-induced dynamic association of coumarin pendants within polymer micelles in aqueous solution. Methods of absorption and emission spectra, solution transmittance, dynamic light scattering (DLS), and atomic force microscope (AFM) were applied. It was f...

Influence of Film Casting Method on Block Copolymer Ordering in Thin Films
关键字:block copolymer, thin films, self-assembling, residual stress
We study the orientation of the cylinder phase of the block copolymer (BCP) poly(styrene-block-methylmethacrylate) (PS-b-PMMA) in thin spun-cast films. We hypothesize that the slow solvent evaporation of the flow-coated films leads to films having higher residual stresses than spun-cast films because of a relatively inhibited transport of the solvent out of the film during drying, and annealin...

Thermodynamic Properties of Li+-Containing Block Copolymer Electrolyte
关键字:block copolymer electrolyte, self-consistent field theory, polyethylene oxide, lithiumion
There is considerable current interest in polymer containing ions, particularly in the energy arena. A promising system for rechargeable battery applications consists of lithium (Li+) salt dissolved in diblock copolymers of polyethylene oxi...

Synthesis and characterization of core-shell fluoroacrylate copolymer latex
关键字:fluoroacrylate copolymer, core-shell structure, emulsion polymerization
Core-shell fluoroacrylate copolymer latex was synthesized via semi-continuous seed emulsion polymerization. Ethyl acrylate (EA) was used for the core, and methyl methacrylate (MMA), butyl acrylate (BA), methacrylate acid(MAA), and hexafluorobutyl met...
