Abstract

Surface modification of linear low-density-polyethylene (LLDPE), ethylene-co-vinyl acetate (EVA), and clay nanoparticles composite films was promoted by potassium permanganate solutions in HCl acidic medium using eight conditions by variation times and temperature, also concentrated oxidation solution of LLDPE and EVA blend films shows a very good clarity and tensile properties, this property can be improved by adding the clay nanoparticles as a filler in the composite. The influence of electron beams (EB) irradiation and amount of clay nanoparticles loading on the overall properties of linear low-density polyethylene (LLDPE) /ethylene-co-vinyl acetate blends was investigated. Samples were subjected to the EB irradiation with the dose values of 75 and 150kGy, afterwards mechanical and thermal properties of the LLDPE/EVA blends with and without clay nanoparticles at different irradiation dosages were utilized in order to analyze the characteristics of the final composite. These enhanced properties are due to the homogenize dispersion of Clay nanoparticles in LLDPE matrix. Moreover, in order to verify these characteristics and compare composite samples with and without Clay nanoparticles (Cloisites 30B), some tests such as DSC, TGA, PSA, SEM and Optical Micrographs (OM) were taken from the samples.

电子束改善纳米复合材料、线性低密度聚乙烯、乙烯-醋酸乙烯酯和纳米粘土颗粒的形貌和性能

高锰酸钾溶液在HCl酸性介质中对线性低密度聚乙烯(LLDPE)、乙烯-醋酸乙烯(EVA)和粘土纳米粒子复合薄膜进行了8种条件下的表面改性，通过改变改性次数和温度，LLDPE和EVA共混膜的浓缩氧化溶液显示出良好的透光性和拉伸性能，在复合材料中加入粘土纳米粒子作为填料可以改善这一性能。研究了电子束(EB)辐照和粘土纳米颗粒负载量对线性低密度聚乙烯(LLDPE) /乙烯-共醋酸乙烯共混物综合性能的影响。对样品进行75和150kGy剂量的EB辐照，然后利用不同辐照剂量下添加和不添加粘土纳米粒子的LLDPE/EVA共混物的力学和热性能，分析最终复合材料的特性。这些增强的性能是由于粘土纳米颗粒在LLDPE基体中的均匀分散。此外，为了验证这些特性，并比较有和没有粘土纳米颗粒(clothes30b)的复合样品，从样品中提取了一些测试，如DSC, TGA, PSA, SEM和光学显微照片(OM)。

期刊介绍： Polymers from Renewable Resources, launched in 2010, publishes leading peer reviewed research that is focused on the development of renewable polymers and their application in the production of industrial, consumer, and medical products. The progressive decline of fossil resources, together with the ongoing increases in oil prices, has initiated an increase in the search for alternatives based on renewable resources for the production of energy. The prevalence of petroleum and carbon based chemistry for the production of organic chemical goods has generated a variety of initiatives aimed at replacing fossil sources with renewable counterparts. In particular, major efforts are being conducted in polymer science and technology to prepare macromolecular materials based on renewable resources. Also gaining momentum is the utilisation of vegetable biomass either by the separation of its components and their development or after suitable chemical modification. This journal is a valuable addition to academic, research and industrial libraries, research institutions dealing with the use of natural resources and materials science and industrial laboratories concerned with polymer science.
