基于辐照技术制备的纳米银薄膜表征及性能研究
Structral Characterization and Properties of Nano-silver Film Prepared by Irradiation
摘要
Abstract
Nano-silver has a highly effective anti-bacterial anti-corrosion functions.In order to develop a new type of antibacterial packaging materials,nano-silver particles were made by irradiation and applied in the preparation of nano-silver-polyethylene(PE) film material.Characterization and physical properties were also measured including the effect of nano-siver content on the transmittance,moisture permeability and mechanical strength of the films.Infrared measurements showed that a characteristic absorption peak appeared at the wavenumber of 1 046 cm-1 after nano-silver was added to the film.UV absorption indicated that a characteristic absorption peak appeared at the wavelength of 366 nm.The characteristic exothermic peak was appeared in the temperature at 340℃.The determination of material's physical properties showed that the transmittance reduced,the moisture permeability slightly decreased,and the mechanical strength increased.Therefore,nano-silver was successfully added to PE film,and the material had good physical properties,and could be used as packaging materials.This study provided theoretical basis for the preparation of new antibacterial packaging materials.关键词
