纳米Fe3O4/纤维素抗静电复合包装膜的研究

目的提高纤维素膜的防静电性能,扩大其在包装方面的应用。方法以木质纤维素为原料,利用原位共沉淀法制备出纳米Fe_3O_4/纤维素复合包装膜,探讨Fe_3O_4/纤维素复合包装膜的力学性能、耐水性能及防静电性能。结果随着铁离子浓度的增加,Fe_3O_4/纤维素复合包装膜的抗拉强度从10.57 MPa增加到14.78 MPa,抗水性从0.27提高到0.38,表面电阻率逐渐下降。结论相比纤维素膜,复合薄膜具有较好的抗静电性能,且在低湿的环境下其抗静电性能更稳定。

Nano-Fe3O4/Cellulose Anti-electrostatic Composite Packaging Membrane

This study was aimed to improve the antielectrostatic properties of the cellulose membrane, and expand its packaging application. Nano-Fe3O4/cellulose composite packaging membranes were prepared by using in-situ co-precipitation method, with the wooden cellulose as raw material. The mechanical properties, water resistance and anti-electrostatic properties of the Fe3O4/cellulose composite packaging membranes were investigated. The results showed that with increasing concentration of ferric ion, the mechanical properties and the water resistance of Fe3O4/cellulose composite membranes increased from 10.57 MPa and 0.27 to 14.78 MPa and 0.38, respectively, while the surface resistivity of the composite membranes gradually decreased. Compared to the cellulose membrane, the composite membranes had better anti-electrostatic properties, and the anti-electrostatic properties were more stable in low humidity environment.
