Abstract：To address the problems of skin thermal damage after photoelectric therapy,κ-carrageenan and konjac glucomannan were used as the main raw materials to prepare a gel film material for skin cooling after photoelectric therapy,and its morphological structure,mechanical properties,cooling performance and physical and chemical properties were comprehensively characterized.The results showed that when the mass ratio of KC to KGM was 5.5:4.5 and the mass concentration of the total dry matter was 10 g/L,the prepared KC/KGM gel film could reduce the surface temperature of artificial skin from(61.28±0.52)℃ to(37.88±0.55)℃ within 25 min.The tensile strength and elongation at break were(0.11±0.03)MPa and(160.63±5.92)％,respectively.The compressive strength can reach(0.19±0.01)MPa.The moisture retention rate of the gel film prepared at 25 ℃ was(86.04±1.72)％within 25 min.The appearance of the gel film was transparent and flat,the cold and hot resistance was satisfying,which met the relevant sensory and physical and chemical performance requirements specified in the mask standard(QB/T 2872-2017).
