저밀도폴리에틸렌(LDPE)/꽃 모양 산화아연(FZnO) 복합필름의 제조 및 물성 분석
Preparation and Characterization of Low Density Polyethylene (LDPE) and Flower-like Zinc Oxide (FZnO) Composite Films
Flower-like zinc oxide (FZnO) was successfully synthesized via a sonochemical process. The chemical structure, morphology, and antimicrobial properties of as- prepared FZnO were investigated. Additionally, pure LDPE and five different LDPE/FZnO composite films were prepared with different FZnO content by using a twin screw extruder. According to the FTIR and SEM analyses, there exists weak interfacial interaction between LDPE and FZnO. Compared with pure LDPE, the LDPE/FZnO composite films showed UV barrier and enhanced antimicrobial activity against Escherichia coli (E. coli) as a Gram-negative micro-organism and Staphylococcus aureus (S. aureus) as a Gram-positive micro-organism. To enhance the interfacial interaction and good dispersion of FZnO into the LDPE matrix, and resultantly to such as UV barrier and antimicrobial properties of LDPE/FZnO composite films as the packaging materials, further efforts are required.
