Cationic polymers are one of the major nonviral gene delivery vectors investigated in the past decade. In this study, we synthesized several cationic copolymers using atom transfer radical polymerization (ATRP) for gene delivery vectors: pluronic F127-poly(dimethylaminoethyl methacrylate) (PF127-pDMAEMA), pluronic F127-poly (dimethylaminoethyl methacrylate-tert-butyl acrylate) (PF127-p(DMAEMA-t...

This paper represents a continuation of the series concerning experimental determination of vapour–liquid equilibria (VLE) in diluted polymer + solvent systems. In the previous papers we dealt with the polymeric flow improvers + toluene, hexane, chloroform1,2, poly(acrylic acid) + water3, poly(methyl methacrylate) + acetone3, and poly(methyl methacrylate) + 2-butanone4 systems. The aim of this ...

A pseudo-polycation was prepared based on the supramolecular cucurbit[8]uril ternary complex. It was then layer-by-layer assembled with poly(acrylic acid) to fabricate a stimuli-responsive film, which exhibited disassembly properties in response to stimuli, providing a supramolecular route for the fabrication of free-standing thin films.

Continuous self-assembled growth of both the organic and inorganic components of materials with nacre-like structure is achieved upon mineralisation of chitin and chitosan scaffolds using a combined soaking method and the inclusion of poly(acrylic acid) and chitosan oligomers as additives.

We demonstrate an approach to the assembly of DNA-containing polyelectrolyte multilayers that can be used to promote rapid release of DNA from surfaces. The approach is based on layer-by-layer incorporation of poly(acrylic acid) to promote rapid erosion in physiologically relevant media.

Abstract The tribological behavior of 316L stainless steel/CoCrMo alloy contacts under aqueous lubrication was investigated in this work. Three types microgels including poly(N-isopropylacrylamide) (PNIPAM), polyacrylic acid (PAA), and poly(N-isopropylacrylamide-co-acrylic acid) (PNIPAM-co-PAA) were prepared used as lubricant additives solutions. Tribological tests conducted using a ball-on-dis...

The use of short chain block copolymer melts as nanostructured templates with sub-10 nm domains is often limited by their low segregation strength ( N). Since increasing molar mass to strengthen segregation also increases the interdomain spacing of block copolymer melts, it is more desirable to increase the Flory-Huggins segment-segment interaction parameter, , to produce strong segregation. We...
