SEMI-INTERPENETRATING POLYMER NETWORK-BASED RESPONSIVE MATERIAL AND APPLICATION THEREOF

Document Type and Number:

WIPO Patent Application WO/2021/109889

Kind Code:

A1

Abstract:

The present invention discloses a semi-interpenetrating polymer network-based responsive material, which comprises a semi-interpenetrating polymer network formed by a liquid crystal elastomer and a cholesteric liquid crystal polymer network, wherein the cholesteric liquid crystal polymer network is formed by polymerization of a liquid crystal mixture including a liquid crystal monomer, the liquid crystal monomer include one or more liquid crystal monomer compounds, and at least one of the liquid crystal monomer compounds is a monofunctional liquid crystal monomer. In the semi-interpenetrating polymer network, the liquid crystal elastomer and the cholesteric liquid crystal polymer network can undergo phase separation with temperature changes, thereby realizing reversible color change. The responsive material does not need to change color by solvent swelling, can obtain a desired coating by a conventional process such as coating, and has good application prospects in the fields of temperature response liquid crystal device, temperature response coating, anti-counterfeiting label and monitoring indication.
