摘　　要：Organic mechanophores have been widely adopted for polymer mechanotransduction.However,most examples of polymer mechanotransduction inevitably experience macromolecular chain rupture,and few of them mimic mussel’s mechanochemical regeneration,a mechanically mediated process from functional units to functional materials in a controlled manner.In this paper,inorganic mechanoluminescent(ML)materials composed of CaZnOS-ZnS-SrZnOS:Mn2+were used as a mechanotransducer since it features both piezoelectricity and mechanolunimescence.The utilization of ML materials in polymerization enables both mechanochemically controlled radical polymerization and the synthesis of ML polymer composites.This procedure features a mechanochemically controlled manner for the design and synthesis of diverse mechanoresponsive polymer composites.
