Abstract

This paper describes a newly developed testing method for determination of the adhesivity of a film sintered from thermoplastic powder. This method is based on the modified EN 15337 standard. Application of this method enables an effective development of thermoplastic composites with enhanced adhesion between reinforcement and matrix and/or high-quality joints between plastics and dissimilar materials. The proposed method was successfully tested on a series of polyethylene powders treated in the oxygen atmosphere for 0-1200 s. Adhesion to metal and glass substrates in dependence on treatment conditions is described along with powder wettability and X-ray photoelectron spectroscopy analysis. The results show an increase in adhesion to metal by 580% and to glass by 1670% for the longest treatment time, compared to a nontreated powder. Sintering of treated powders revealed a strong influence of treatment time on the melting process. The XPS analysis confirmed the formation of new oxygen groups (C-O, C=O, O-C=O). The method reveals a specific behavior of powders based on treatment conditions, which is crucial for the optimization of plasma treatment for the improved adhesion, applicability of polymer powders, and a development of composite materials.

摘要

本文描述了一种新开发的用于测定热塑性粉末烧结膜粘附性的测试方法。该方法基于修改后的EN 15337标准。应用此方法能够有效地开发热塑性复合材料，增强增强材料与基体之间的粘附力和/或塑料与异种材料之间的高质量接头。所提出的方法已在一系列在氧气气氛中处理0至1200秒的聚乙烯粉末上成功测试。描述了根据处理条件对金属和玻璃基材的粘附性，以及粉末润湿性和X射线光电子能谱分析。结果表明，与未处理的粉末相比，最长处理时间下对金属的粘附力增加了580%，对玻璃的粘附力增加了1670%。处理过的粉末烧结显示出处理时间对熔化过程有很大影响。XPS分析证实了新氧基团（C-O、C=O、O-C=O）的形成。该方法揭示了基于处理条件的粉末的特定行为，这对于优化等离子体处理以提高粘附性、聚合物粉末的适用性以及复合材料的开发至关重要。
