Journal of the American Chemical Society, 2019
In this report, we merge block copolymers with vitrimers in an effort to realize the prospect of higher-order, nanoscale control over associative cross-link exchange and flow. We show the use of controlled polymerization as a vital tool to understand fundamental structure-property effects through the precise control of polymer architecture and ...

Polymer Bulletin, 1996
The preparation of acid chloride of poly(propylene oxide), PPO, the synthesis of prepolymer poly(p-benzamide), and of block copolymers of poly(p-benzamide)-b-poly(propylene oxide) are reported. The preparation of prepolymer poly(p-benzamide), PBA, and activated PPO, as well as PBA-PPO block copolymer are discussed according to their FTIR spectra.

Orienting Block Copolymer Microdomains with Block Copolymer Brushes
ACS Nano, 2012A simple, rapid, and robust technique for controlling the self-assembly of block copolymers (BCPs) with a large segmental interaction parameter, χ, is described using a surface modified with anchored BCP brushes. End-functionalized poly(styrene-b-ethylene oxide)s (PS-b-PEOs), where the fraction of PS (f(PS)) was varied, end-functionalized neat PS, and ...

Skin delivery by block copolymer nanoparticles (block copolymer micelles)
International Journal of Pharmaceutics, 2015Block copolymer nanoparticles often referred to as "block copolymer micelles" have been assessed as carriers for skin delivery of hydrophobic drugs. Such carriers are based on organic biocompatible and biodegradable materials loaded with hydrophobic drugs: poly(lactide)-block-poly(ethylene glycol) copolymer (PLA-b-PEG) nanoparticles that have a solid ...

Current Opinion in Solid State and Materials Science, 1999
The efficient synthesis of structurally well-defined block copolymers is exciting and important area of research. This article describes several methods for the preparation of di- and triblock copolymers. Examples are taken from the literature and include anionic, cationic, free-radical and metal-catalyzed polymerizations that are useful for the ...

Prismatic Block Copolymer Hexosomes
ACS Nano, 2023Cubosomes and hexosomes are recent solution morphologies with an ordered porous structure and are observed for lipids and amphiphilic block copolymers (BCPs) with high hydrophobic fractions. Whereas lipid hexosomes typically exhibit a prismatic shape, BCP hexosomes have so far only been observed as closed microspheres where inner channels are not ...

Nanostructured block copolymer muscles
Nature Nanotechnology, 2022High-performance actuating materials are necessary for advances in robotics, prosthetics and smart clothing. Here we report a class of fibre actuators that combine solution-phase block copolymer self-assembly and strain-programmed crystallization. The actuators consist of highly aligned nanoscale structures with alternating crystalline and amorphous ...

Linear Block Copolymer Synthesis
Chemical Reviews, 2022Block copolymers form the basis of the most ubiquitous materials such as thermoplastic elastomers, bridge interphases in polymer blends, and are fundamental for the development of high-performance materials. The driving force to further advance these materials is the accessibility of block copolymers, which have a wide variety in composition ...
