This invention provides a scrollable and foldable transparent polysiloxane film and its preparation and self-healing method. 2-Hydroxyethyl disulfide, diisocyanate and alkane chloride were mixed and reacted to get disulfide-containing diisocyanate. α,ω-Aminopropyl terminated polydimethylsiloxane, diisocyanate and alkane chloride were mixed and reacted get linear chain-extended polydimethylsiloxane. Linear chain-extended polydimethylsiloxane, multi-amino terminated hyperbranched polysiloxane, disulfide-containing diisocyanate and alkane chloride were mixed and poured into a mould. After drying, the scrollable and foldable transparent polysiloxane film was obtained. The polysiloxane film described in this invention are constructed by dynamic physical crosslinking induced by hydrogen bond and permanent chemical crosslinking generated by hyperbranched polysiloxane. Hence, the polysiloxane film achieves both high stiffness and toughness. The good self-healing behavior of the polysiloxane films is originated from the temperature controlled dissociation of hydrogen bonds and exchange reaction rate of disulfide bonds.
