We investigated the morphology and swelling behavior of a new graft-type of anion exchange membrane (AEM) containing 2-methylimidazolium groups by using a contrast variation small angle neutron scattering (SANS) technique. These AEMs were prepared by radiation-induced grafting of 2-methyl-1-vinylimidazole and styrene into poly(ethylene-co-tetrafluoroethylene) (ETFE) films and subsequent N-alkyl...

A novel near-infrared (NIR) electrochromic polyelectrolyte consisting of anthraquinone imide (AQI) pendants and a poly(1-vinylimidazole bromide) main chain was synthesized via radical polymerization. Its AQI content was varied by copolymerization with 1-vinyl-3-butylimidazole bromide to improve the processability of the polymer as well as the monomer conversion. The electrochemical and electroc...

This study reports the synthesis of novel poly(1-vinylimidazole)-b-poly(9-vinylcarbazole) (PVI-b-PVK) block copolymers with varying monomer ratios using reversible addition-fragmentation chain-transfer (RAFT) polymerization and their incorporation in responsive composite materials. Specifically, non-covalent exfoliation two different conductive fillers, multi-walled carbon nanotubes (MWCNTs) or...

Electrolysis is seen as a promising route for the production of hydrogen from water, part move to wider “hydrogen economy”. The electro-oxidation renewable feedstocks offers an alternative anode couple (high-overpotential) electrochemical oxygen evolution reaction developing low-voltage electrolysers. Meanwhile, exploration new membrane materials also important in order try and reduce capital c...

Highly selective molecularly imprinted polymers (MIPs) towards benzyl methyl ketone (BMK) were synthesized for application as recognition elements in a capacitive sensor. A computational approach was employed to select the most appropriate monomers and cross-linkers. Using selected compounds, different polymerization techniques protocols compared order study effect on MIP performance characteri...

Background . As scientific knowledge about the peculiarities of structure and functional properties skin increased, it became clearer that during transdermal administration, drug may accumulate in deep layers dermis subsequently get diffused into bloodstream even after therapeutic system (TTS), also called patch, had been removed. Objective : to quantify active substances remaining an animal TT...
