Abstract Critical issues such as leakage, degradation, and thermal response hysteresis have become the focus in application of phase change materials (PCMs) area management fabrics. The encapsulation PCMs prepared microcapsules using polysiloxanes, etc. a component unit crosslinking agents represents highly promising avenue research. In this work, organosilicon crosslinkers are employed for poly (methyl methacrylate) (PMMA) microencapsulation paraffin wax microcapsule (mPCMs). results showed that increasing degree helps to improve performance mPCMs by smoothing shell surface, but excessive leads flocculation, which reduces its performance. produced with 10% wt agent gave highest efficiency, melting enthalpy crystallization 81.3%, 285.0 J g −1 253.1 , respectively. obtained also combined epoxy resin fabrics form composite materials. Notably, polysiloxane‐modified permit resins achieve maximum temperature reduction 25 °C. By adjusting mass ratio crosslinkers, enable textiles reach 17 °C while maintaining satisfactory air permeability.
