Controlled/living radical polymerization was developed to synthesize branched polyacrylates and polystyrene with tunable degrees of branching low dispersities. This method is based on a polymerization-induced process that occurs when n-butyl α-bromoacrylate copolymerized under atom transfer conditions. novel demonstrates excellent synthetic versatility, enabling the preparation complex macromolecular architectures constructed from branched-polymer building blocks.
Analog systems may allow image processing, such as edge detection, with low computational power. However, most demonstrated analog systems, based on either conventional 4-f imaging or nanophotonic structures, rely coherent laser sources for illumination, which significantly restricts their use in routine tasks ambient, incoherent illumination. Here, we a metalens-assisted system that can optoelectronic detection under ambient illumination conditions. The metalens was designed to generate...
Fast lithium ion (Li+) transport in solid-state polymer-matrix conductors is desperate demand a wide range of room-temperature scenarios but remains formidable challenge. Herein, we designed class electrolytes based on mixed-graft block copolymers (mGBCPs) containing short poly(ethylene oxide) (PEO) and polydimethylsiloxane (PDMS) side chains.

We have performed dissipative particle dynamics simulations to study the self-assembly of ABC-type bottlebrush copolymers (BBCPs), one portion whose backbone is grafted by pairs A-blocks and other B/C-blocks in pairs, focusing on effects number A side chains, length B chains relative that C rigidity formation hierarchical structures. structures with superstructures formed phase separation between substructures C-blocks are observed. Some similar those self-assembled ABC star copolymers,...
Abstract Mixed‐graft block copolymers (mGBCPs) consist of two or more types polymeric side chains grafted on a linear backbone in random, alternating, pseudo‐alternating sequence. They can phase‐separate with the serving as interface blocks, and dominate their self‐assembly behavior. mGBCPs are an accessible polymer architecture for exploring idea encoding properties through macromolecular architecture, there distinct structural components that be tuned: chains. In this Concept article,...
Polyvinyl alcohol (PVA) gel has a very wide range of applications in agriculture, military, industry, and other fields. As widely used water-soluble polymer, PVA good mechanical properties, excellent spinnability, hydrophilicity, remarkable physical chemical stability, film formation, is non-polluting, exhibits natural degradation biocompatibility.
