Synthesis and characterization of PIL/pNIPAAm hybrid hydrogels
Current Directions in Biomedical Engineering, 2016 In this study, varying amounts of NIPAAm and an ionic liquid (IL), namely 1-vinyl-3-isopropylimidazolium bromide ([ViPrIm]+[Br]−), have been used to synthesize hybrid hydrogels by radical emulsion polymerization. Amounts of 70/30%, 50/50%, 30/70%, 15/85%

Trithiocarbonate-Functionalized PNiPAAm-Based Nanocomposites for Antimicrobial Properties [PDF]
Polymers, 2018 In this study, four trithiocarbonate-functionalized PNiPAAms with different molecular weights were synthesized and used as a matrix to form composites with silver nanoparticles. Nanocomposites with several polymer-to-silver ratios P:Ag+ were prepared in order to evaluate the influence of silver loading.
