A PREPARATION METHOD OF TEMPERATURE AND PH SENSITIVE HYDROGEL

摘要

PURPOSE: A method for manufacturing temperature and pH sensitive hydrogel is provided to ensure high mechanical strength and to use for an actuator such as sensor or switch, drug carrier, prosthesis, and artificial skin and muscle. CONSTITUTION: A method for manufacturing temperature and pH sensitive hydrogel comprises: a step of preparing microcapsule; a step of polymerizing and crosslinking the microcapsule, to obtain IPN(interpenetrating polymer network) hydrogel. The crossliking is performed by reacting polyvinyl alcohol and poly N-isopropyl acrylamide with crosslinking agent.
