Self-healable, multilayered organosiloxane films were prepared thermal conversion of lamellar organosiloxane films containing poly(ethylene oxide)-polydimethylsiloxane-poly(ethylene oxide) block copolymers. The incorporation of silanolate groups enabled crack healing through dynamic siloxane equilibration. The enhanced hardness and suppressed cyclic siloxane formation resulting from the multilayered structure exhibit potential for practical applications.
