Copolymers of methyl methacrylate (MMA) with methacrylamide (MAA ... with values usually found for polymer grafted CNT composites. For example 24 wt% of PS using silane-coupling agent [11] or 37 wt% ...

Films of pure poly(styrene) (PS), pure poly(methyl methacrylate) (PMMA), a 1:1 PS/PMMA blend and a PS-b-PMMA copolymer, were prepared and tested for cell adhesion ...

ABSTRACT: Amid the escalating plastic pollution issue, the development of biodegradable and recyclable polymeric materials has become a focus within the scientific community. Chain extenders, which ...

A recently developed block copolymer could help push the limits of integration and miniaturization in semiconductor manufacturing, report scientists in Tokyo Tech and TOK. Chemically tailored for ...

Chemically Tailored Block Copolymers for Generating Highly Reliable Nanometer-Scale Patterns. (Image: Tokyo Tech) (click on image to enlarge) The newly developed BCP was created from polystyrene-block ...

Thermoplastic elastomers can be synthesized in a one-pot process using ARGET. PS-PEA-PS and PMMA-PBA-PMMA block copolymers were made in such a way,(3) and mechanical testing should be done soon and ...

Fig 1: Representation of PS-b-PMMA block co-polymer. The length of each block, controlled by the number of monomers in each block, is the determining factor for pitch. Source: Semiconductor ...

This article reviews various strategies that have been implemented in the past decade to fabricate devices at nanoscale using block copolymer thin films ... For instance, poly (styrene-block-methyl ...

The scientists visualized the space occupied by each PS-b-PMMA micelle using Wigner-Seitz cells (a primitive unit cell). The work indicated the volumes of the micelles to be constant, validating ...

random copolymer (RCP) brush layer grafted to the substrate prior to BCP deposition. In this work, we investigate the self-assembly process and lateral order evolution in RCP + BCP systems consisting ...
