Abstract:Polyampholyte hydrogels with tunable charge are synthesized by a facile two-step approach including the free radical crosslinking copolymerization of tert-butoxycarbonylaminomethylacrylate (tBAMA) with N,Nˊ-Methylenebisacrylamide and subsequent deprotection. Thermal, photo- and redox-initiating methods were utilized in the synthesis of crosslinked PtBAMA and the resulting polymer networks swell during deprotection in a mixture of trifluoro acetic acid/water. While the crosslinked PtBAMA forms organogels in var… Show more
