中文摘要:
      目的 探究以熔融共混方式制备的纳米银复合膜的性能。方法 采取熔融共混,吹塑成膜方式制备含不同添加剂的纳米银-聚乙烯复合包装薄膜。使用扫描电镜表征纳米银粉末和纳米银-聚乙烯复合膜内银的粒径大小,并用傅里叶变换红外光谱对复合膜的化学键进行表征。探究纳米银以熔融共混的方式复合到聚乙烯内后,对薄膜颜色、透光性、氧气透过率、水蒸气透过率的影响。结果 纳米银粉末和复合膜内的银均含不同粒径,纳米银的加入未产生明显的新化学键,薄膜的透光率降低了3.9%~12.2%,氧气透过率提高了6.56~117.17 cm3/(m2•d•(0.1 MPa)),水蒸气透过率提高了0.038~1.791 g/(m2•d)。结论 以熔融共混方式制备的纳米银-聚乙烯复合膜透光率下降,氧气透过率和水蒸气透过率得到提高,未形成明显的新化学键。
英文摘要:
      The work aims to study the properties of nano-silver composite films prepared by melt blending. Nanosi lver-polyethylene composite packaging films with different additives were prepared by melt blending and film blowing. Particle size of nanosilver powder and silver in nanosilver-polyethylene composite films was characterized by scanning electron microscope and the chemical bonds within the composite films were characterized by Fourier transform infrared spectrometer. The effects on the color, light transmittance, oxygen permeability and water vapor permeability of the films were examined after the nanosilver-polyethylene composites were prepared by melt blending. The results showed that nano-silver powder and silver in the composite films were of different particle sizes, and the addition of nano-silver resulted in no obviously new chemical bonds. As a result, the light transmittance of composite films was reduced by 3.9%~12.2%, the oxygen permeability was improved by 6.56~117.17 cm3/(m2•d•(0.1 MPa)), and the water vapor permeability was improved by 0.038~1.791 g/(m2•d). The light transmittance of nanosilver-polyethlene composite film prepared by melt blending is decreased, the oxygen permeability and water vapor permeability are improved, and no obviously new chemical bonds are formed.
