摘要
摘要聚乳酸在食品包装工业中具有替代石油基材料的潜力。本文研究了氧化锌纳米颗粒、聚乙二醇400和吐温80作为增塑剂对聚乳酸薄膜性能的影响。为了更准确地研究其力学性能,试验重复进行了四个月。采用实验设计方法考察了添加剂对测定因子的影响,并结合TOPSIS技术确定了最佳组合。结果表明,不同材料的加入增加了不透明度,其中P400/ZnO(6.82±0.07 mm−1)对不透明度的影响最大。增塑剂的存在增加了薄膜的亲水性和水蒸气渗透性。接触角最高(85.33°±4.00),水蒸气渗透率最低(0.074±0.002 g mm/kPa h m 2)。P400/T80/ZnO的最低弹性模量、最高抗拉强度和断裂伸长率分别为1.18±0.17 GPa(第1个月)、96.28±3.17 MPa(第4个月)和76.82±27.22%(第1个月)。增塑剂对大多数测量因子的影响显著,而纳米颗粒对不透明度和接触角等测量因子的影响显著。方差分析结果表明,薄膜类型对力学性能有显著影响,而储存时间仅对断裂伸长率有显著影响。根据TOPSIS技术得到的结果,选择P400/ZnO作为制备膜中性能最好的组合。
Effects of ZnO nanoparticles, polyethylene glycol 400, and polyoxyethylene sorbitan ester Tween 80 on PLA films properties
Abstract Polylactic acid has the potential to be an alternative to petroleum-based materials in the food packaging industry. In this study, the effect of zinc oxide nanoparticles, polyethylene glycol 400, and Tween 80 as plasticizers on the properties of polylactic acid films was investigated. In order to study the mechanical properties more accurately, the tests were repeated for four months. An experimental design method was used to investigate the effects of additives on the measurement factors and finally to choose the optimal combination with the help of the TOPSIS technique. The results showed that the addition of different materials increased the opacity, most of which being related to P400/ZnO (6.82 ± 0.07 mm −1 ). The presence of plasticizers increases the hydrophilicity of the film and the water vapor permeability. The highest contact angle (85.33° ± 4.00) and the lowest water vapor permeability (0.074 ± 0.002 g mm/kPa h m 2 ) were related to neat PLA film. The lowest modulus of elasticity, the highest tensile strength and elongation at break were related to P400/T80/ZnO (1.18 ± 0.17 GPa, first month), PLA/ZnO (96.28 ± 3.17 MPa, fourth month), and P400/ZnO (76.82 ± 27.22 %, first month), respectively. The effect of plasticizers was significant in most of the measurement factors, but the effect of nanoparticles was significant in some cases such as opacity and contact angle. The results of an ANOVA analysis showed that the effect of film type on the mechanical properties was significant, and the effect of storage time was only significant on the elongation at break. According to the results obtained from the TOPSIS technique, P400/ZnO was chosen as the combination with the best features among the produced films.
