Preparation method and application of agarose-bacterial cellulose composite gel

The invention discloses a preparation method and application of agarose-bacterial cellulose composite gel, and belongs to the technical field of composite gel. The preparation method comprises the following steps: (1) dissolving agarose in deionized water, dissolving and stirring to prepare an agarose aqueous solution with the concentration of 0.5-2wt%; (2) soaking the bacterial cellulose gel in an agarose aqueous solution for compound finishing at the temperature of 80-90 DEG C to obtain agarose intercalation modified bacterial cellulose gel; and (3) cooling the modified gel to obtain the agarose-bacterial cellulose composite gel. The prepared composite gel has good mechanical properties, according to the application of the composite gel in a temperature sensor, the drying treatment condition is that drying is carried out at 70-80 DEG C, the swelling condition is that the composite gel is soaked in deionized water at 60-90 DEG C for swelling, and the composite gel is endowed with shrinkage-swelling property,
