23 Jul Preparation method of pH and temperature dual responsive composite hydrogel based on cellulose polymer surfactant
Abstract
The invention discloses a preparation method of a pH and temperature dual responsive composite hydrogel based on a cellulose polymer surfactant. The preparation method includes the steps of stably dispersing a thermosensitive monomer with the cellulose polymer surfactant and then adding a crosslinking agent, a comonomer and an initiator for polymerization to obtain the pH and temperature dual responsive composite hydrogel. The preparation method adopts the cellulose polymer surfactant as an emulsifier, so that the thermosensitive monomer is stably dispersed in deionized water; at the same time, the prepared hydrogel has both temperature responsiveness and pH responsiveness, and can be applied to the fields of drug controlled release, tissue engineering, water and soil moistening agents, food fresh-keeping packaging materials and the like.
