A novel self-healing poly(amic acid) ammonium salt hydrogel with temperature-responsivity and robust mechanical properties†
Abstract
The fabrication of hydrogels with excellent self-healing properties and high mechanical strength has become a challenging and fascinating topic. The aim of this study is to fabricate a novel robust PAS hydrogel with self-healing properties. The self-healing mechanism and possible interactions between PAS chains of the hydrogel are proposed.
