A Rapid Recoverable Shape Memory Polymer with Topologically Well-controlled Poly(ethyl methacrylate) Structures

Abstract

Many of unique properties in one conventional crosslinking shape memory network is not found at the same time, in which is a large challenge for developing the advanced shape memory functional materials. In this work, the topologically well-controlled network shape memory poly (ethyl methacrylate) (CN-SMPEMA) is designed and fabricated by introducing two tetra-armed functional structures simultaneous as macromolecule units to promote switch segments and net-points uniform distribution via a combined technology of the unique controllable the atom transfer radical polymerization (ATRP) and copper(Ι)-catalyzed azide-alkyne cycloaddition (CuAAC). Compared with conventional crosslinking networks, so-prepared CN-SMPEMA not only exhibits combination of excellent mechanical property, shape fixity, shape recovery ratios and outstanding cycling stability, but also displays rapid recoverability. Additionally, a feasible molecular mechanism for the shape memory effect of the CN-SMPEMA system is analyzed and proposed. We anticipate that such a topologically well-defined network shape memory material with multiple excellent properties will broaden practical application range of the acrylate-based shape memory polymer materials.
