Synthesis of conducting polysiloxane-polypyrrole graft copolymers

, 2002
Polysiloxane-polypyrrole graft copolymers have been synthesized by a series of chemical reactions and subsequent electropolymerization. First, the hydrosilation of 4-vinyl aniline by dimethyl-methylhydrosiloxane copolymer gave the corresponding ...

Acrylonitrile Block and Graft Copolymers [PDF]

Pure and Applied Chemistry, 1976
Abstract This paper presents a review of the methods available for preparing block and graft copolymers in which one component is acrylonitrile. Methods using polymer ions and polymer radicals are considered together with a useful new technique based on reactions of nitrile groups with amide compounds of group IV transition metals.

Self‐Assembling Copolymers Encapsulating Single Endothelial Cells Induce Endogenous ECM Deposition and Vascular Regeneration

Advanced Materials, EarlyView.
This study presents the first demonstration of stable sub‐50‐micron single‐cell GPM vesicles fabricated through the intrinsic self‐assembly of an amphiphilic copolymer. Hierarchical assembly of cell containing GPM vesicles into microspheres enable tunable, sustained cell delivery with immune protection.

Tamper‐Responsive Physical Unclonable Functions via Graphene‐Interlayered Block Copolymer Random Structures

Advanced Materials, EarlyView.
Self‐invalidating multilayer physical unclonable functions (PUFs) integrate fingerprint‐like metal nanopattern bilayers from block copolymer templates with highly reactive reduced graphene oxide (rGO) interlayers. This tamper‐responsive architecture blocks all unauthorized physical and chemical replication attempts while autonomously deactivating ...

UCST‐Responsive PMEGA: From Solution Behavior to Functional Hydrogel Surfaces

Advanced Materials Interfaces, EarlyView.
PMEGA is used as a versatile water‐based UCST‐responsive platform for engineering microstructured hydrogel coatings via a thiol–ene CLAG approach. From PMEGAs of well‐defined UCST properties, the UV‐based CLAG method provides precise control over film thickness, ranging from nanometers to micrometers, and enables high‐resolution patterning.

Smart Electrospun Nanofibers for Controlled Oil‐Water Separation

Advanced Materials Interfaces, EarlyView.
Stimuli‐responsive electrospun nanofibers are reviewed as advanced platforms for controlled oil/water separation. The effects of surface wettability, porous structure, and external stimuli, including pH, temperature, gas, and light, on separation performance are discussed.

Investigation of the decomposition behavior of the fluoroalkyl acrylate homopolymer and its grafted copolymers onto high-density polyethylene

Journal of New Results in Science
In this study, the thermal degradation behavior of both poly(3,3,4,4,5,5,6,6,7,7,8,8,8-dodecafluoro-5-methyloctyl-4-(acryloyloxy) benzoate), poly(ABCF13) and its graft copolymers onto high-density polyethylene (HDPE) was investigated in detail.
