Antistatic packages are used to protect and storage sensitive electronic compounds, plates, and integrated circuit. To produce antistatic packages, polymers must have good mechanical properties and low electrical resistivity to prevent the accumulation of static electricity and damage the stored product. Many polymers can be used to produce packages, especially polyolefins. In the field of sustainable packaging, green low‐density polyethylene (green LDPE) has been highlighting in recent years due to its origin: sugar cane. Thus, it is a green polymer that has the same properties as LDPE obtained from petroleum. Due to its insulating character, it is necessary the addition of conductive fillers, thus in this work, glassy carbon (GC) was used as a conductive filler. GC is a carbon material made from furfuryl alcohol resin obtained from rice husk or sugar cane, it is a conductive material and can decrease the electrical resistivity of the green LDPE/GC composite, making it possible to use as an antistatic packaging. Eco‐friendly green composites based on green LDPE/GC with different contents of GC (0.1, 0.3, and 0.5 wt%) were prepared using a thermokinetic homogenizer. The green composites were characterized by mechanical and thermal properties, structural characteristics, water vapor permeability, optical properties, and impedance spectroscopy. The results indicate that the use of green LDPE/GC composites with low concentrations of GC (0.1 wt%) is feasible for the preparation of antistatic packaging since the green composites showed low electrical resistivity and improvement in elastic modulus.

用于抗静电包装的新型环保绿色复合材料:绿色低密度聚乙烯/玻璃碳

抗静电包装用于保护和存储敏感的电子化合物,极板和集成电路。为了生产抗静电包装,聚合物必须具有良好的机械性能和低电阻率,以防止静电积聚并损坏存储的产品。许多聚合物可用于生产包装,特别是聚烯烃。在可持续包装领域,近年来,绿色低密度聚乙烯(绿色LDPE)因其起源而受到关注:甘蔗。因此,它是一种绿色聚合物,其性质与从石油获得的LDPE相同。由于其绝缘特性,必须添加导电填料,因此在这项工作中,玻璃碳(GC)被用作导电填料。GC是由稻壳或甘蔗中的糠醇树脂制成的碳材料,它是导电材料,可以降低绿色LDPE / GC复合材料的电阻率,从而可以用作抗静电包装。使用热动力学均化器制备了基于绿色LDPE / GC且具有不同GC含量(0.1、0.3和0.5 wt%)的环保绿色复合材料。该绿色复合材料的特征在于机械和热性能,结构特性,水蒸气渗透性,光学特性和阻抗谱。结果表明,使用低浓度GC(0.1 wt%)的绿色LDPE / GC复合材料可用于制备抗静电包装,因为绿色复合材料显示出低电阻率并改善了弹性模量。它是一种导电材料,可以降低绿色LDPE / GC复合材料的电阻率,因此可以用作抗静电包装。使用热动力学均化器制备了基于绿色LDPE / GC且具有不同GC含量(0.1、0.3和0.5 wt%)的环保绿色复合材料。该绿色复合材料的特征在于机械和热性能,结构特性,水蒸气渗透性,光学特性和阻抗谱。结果表明,使用低浓度GC(0.1 wt%)的绿色LDPE / GC复合材料可用于制备抗静电包装,因为绿色复合材料显示出低电阻率并改善了弹性模量。它是一种导电材料,可以降低绿色LDPE / GC复合材料的电阻率,因此可以用作抗静电包装。使用热动力学均化器制备了基于绿色LDPE / GC且具有不同GC含量(0.1、0.3和0.5 wt%)的环保绿色复合材料。该绿色复合材料的特征在于机械和热性能,结构特性,水蒸气渗透性,光学特性和阻抗谱。结果表明,使用低浓度GC(0.1 wt%)的绿色LDPE / GC复合材料可用于制备抗静电包装,因为绿色复合材料显示出低电阻率并改善了弹性模量。使其可以用作抗静电包装。使用热动力学均化器制备了基于绿色LDPE / GC且具有不同GC含量(0.1、0.3和0.5 wt%)的环保绿色复合材料。该绿色复合材料的特征在于机械和热性能,结构特性,水蒸气渗透性,光学特性和阻抗谱。结果表明,使用低浓度GC(0.1 wt%)的绿色LDPE / GC复合材料可用于制备抗静电包装,因为绿色复合材料显示出低电阻率并改善了弹性模量。使其可以用作抗静电包装。使用热动力学均化器制备了基于绿色LDPE / GC且具有不同GC含量(0.1、0.3和0.5 wt%)的环保绿色复合材料。该绿色复合材料的特征在于机械和热性能,结构特性,水蒸气渗透性,光学特性和阻抗谱。结果表明,使用低浓度GC(0.1 wt%)的绿色LDPE / GC复合材料可用于制备抗静电包装,因为绿色复合材料显示出低电阻率并改善了弹性模量。该绿色复合材料的特征在于机械和热性能,结构特性,水蒸气渗透性,光学特性和阻抗谱。结果表明,使用低浓度GC(0.1 wt%)的绿色LDPE / GC复合材料可用于制备抗静电包装,因为绿色复合材料显示出低电阻率并改善了弹性模量。该绿色复合材料的特征在于机械和热性能,结构特性,水蒸气渗透性,光学特性和阻抗谱。结果表明,使用低浓度GC(0.1 wt%)的绿色LDPE / GC复合材料可用于制备抗静电包装,因为绿色复合材料显示出低电阻率并改善了弹性模量。
