Preparation and Properties of Calcium Alginate Nano-Cu_2O Flame Retardant Antimicrobial Membrane Material

摘要

Nano-Cu_2O materials have many excellent properties, it is widely used, to overcome its sparingly solubility in water and poor stability among other defects, anhydrous cupric sulfate as raw materials, preparation of gel of nano-Cu_2O by in stiu reduction method in sodium alginate solution (SA). The structure and morphology of the Cu_2O in the gel was investigated by FT-IR and SEM were tested. On the basis of SA/nano-Cu_2O gel, Calcium Alginate nano-Cu_2O membrane were prepared by vacuum drying and crosslinking with Ca~(2+). The material has flame retardant, antibacterial and other excellent performance. Has a wide range of applications.
