Abstract

This application relates to a bifunctional and flexible hydrogel optical fiber, a preparation method and an application thereof. Raw materials of a fiber core include polyethylene glycol diacrylate (PEGDA), methacrylamide, 2-hydroxyethyl methacrylate (HEMA) and 2,2-diethoxy-phenylacetophenone (DMPA); raw materials of an intermediate fiber layer include Synechococcus cells, PEGDA, gelatin methacrylate (GelMA), anhydrous strontium chloride and DMPA; and raw materials of a cladding include PEGDA, methacrylamide, sodium alginate and DMPA. A continuous and controllable direct oxygen supply function is provided through an optical fiber structure.
