| 摘 要： | 可降解防静电包装材料在保留传统防静电材料性能的前提下,可完全生物降解,符合环保要求。为了制备具有优异力学和导电性能的可生物降解防静电包装材料,本研究先对碳纳米管(CNTs)进行羧基化,然后通过熔融共混法制备PLA/PBAT/CNTs-COOH复合材料。采用傅立叶变换红外光谱仪(FTIR)和差示扫描量热仪(DSC)对制备的复合材料的链结构和热性能进行表征,并且通过万能材料试验机、数字冲击试验机和多功能数据采集仪研究了复合材料的力学和导电性能。结果表明:将CNTs-COOH引入PLA/PBAT体系中,可在不降低拉伸强度的同时,有效提高冲击强度,降低表面电阻率,CNTs-COOH的最佳添加量为1wt%~1.5wt%。该PLA/PBAT/CNTs-COOH复合材料可用于静电敏感产品的防静电包装。

| Abstract: | The biodegradable antistatic packaging material can keep the properties of traditional antistatic materials and meet the environmental protection requirements. In order to prepare the biodegradable antistatic packaging material which has excellent mechanical and electrical properties, the carbon nanotubes （CNTs） were carboxylated and the PLA/PBAT/CNTs- COOH composites were prepared through melt blending method. The chain structure and thermal properties of the composites were characterized by Fourier Transform Infrared Spectrometer（FFIR） and Differential Scanning Calorimeter （DSC）, and the mechanical and electrical properties were also researched by the universal testing machine, the digital impact tester and the multipurpose data acquisition instrument. The results showed that the addition of CNTs-COOH to PLA/PBAT can effectively improve the impact strength and reduce the surface resistance of the composites, without reducing the tensile strength, and the optimum content of CNTs-COOH was 1wt%-1. 5wt%. The PLA/PBAT/CNTs-COOH composites can be used for antistatic packaging for static-sensitive products. |
