Thermo-expandable microspheres strengthened polydimethylsiloxane foam with unique softening behavior and high-efficient energy absorption

Herein, a simple and controllable foaming method was used to prepare the polydimethylsiloxane (PDMS) foams with high compressive resistance and motion-energy absorption efficiency. The thermo-expandable hollow microspheres (TEHM) expanded in PDMS matrix to form the TEHM/PDMS foams, which exhibited strengthened mechanical properties with unique softening behavior and high energy absorption property. The compressive curves of the TEHM/PDMS foams...
