Polyvinylpyridinium-type gradient porous membranes: synthesis, actuation and intrinsic cell growth inhibition†
Abstract
Gradient porous membranes were prepared from a poly(4-vinylpyridinium)-based poly(ionic liquid) together with carboxylic multi-acid compounds via electrostatic complexation. Their unique tuneable actuation kinetics in a humid environment as well as their intrinsic cell toxicity were studied.
