Nanomaterials are used in polymer composites to enhance plastic products' properties. Silver nanoparticles (AgNPs) are added to composites for their antimicrobial and fungicidal properties. Polyethylene terephthalate glycol polymer (PETG) AgNP composite test objects with AgNP mass fraction of 0.5% and 2% were abraded using NIST SP 1200-30 abrasion protocol to find the microplastic (MP) abrasion rates of these nanocomposites over various power inputs. Results showed that the abrasion rate of composite depended on the polymer matrix rather than on the AgNP content in the product. However, AgNPs affected the size and physico-chemical properties and surface qualities of particles produced. Surface attached and protuberant AgNPs were found on the abraded particles. As the mass fraction of nanomaterial increased in the composite, the size range of abraded composite particles produced during abrasion decreased.

量化 AgNP 纳米复合材料的机械磨损：AgNP 含量对磨损产物和微塑料生成率的影响


纳米材料用于聚合物复合材料以增强塑料产品的性能。银纳米颗粒 (AgNP) 因其抗菌和杀菌特性而被添加到复合材料中。使用 NIST SP 1200-30 磨损协议对 AgNP 质量分数为 0.5% 和 2% 的聚对苯二甲酸乙二醇酯聚合物 (PETG) AgNP 复合材料测试对象进行磨损，以找出这些纳米复合材料在不同功率输入下的微塑料 (MP) 磨损率。结果表明，复合材料的磨损率取决于聚合物基体而不是产品中AgNP的含量。然而，AgNPs 影响所产生颗粒的尺寸、物理化学性质和表面质量。在磨损的颗粒上发现了表面附着的和突出的纳米银颗粒。随着复合材料中纳米材料质量分数的增加，磨损过程中产生的磨损复合颗粒的尺寸范围减小。
