Fabrication of Comb-type self-oscillating gels by atom transfer radical polymerization for controlling autonomous swelling/deswelling behavior

Abstract In this study, we show the controlled self-oscillation behavior (i.e., normalized amplitude, swelling rate, and deswelling rate) of self-oscillating gels by introducing grafted chains. The chain was introduced to base gel network “grafting from” method atom-transfer radical polymerization (ATRP). We demonstrated that properties chain, including monomer composition length can lead notable behavior. strategy in study pave way for realizing desirable operational functions biomimetic actuators.
