Abstract The progress in new surface modification techniques towards the manufacture of tailored latex articles is faced with the requirement of new characterization techniques to determine the tribological properties of elastomer surfaces. Thus, the present study aims at the characterization of friction properties of commercially available medical gloves to assess their donning performance. The experimental design of the friction test method involves a linear movement of the glove sample across selected counterpart materials. In the first step, bio-tribological studies with a panel are carried out enabling an objective evaluation of the donning properties of gloves. These results are compared to the coefficient of friction of the gloves against various skin equivalents including polymer based materials, glass and biological tissue. In terms of skin friction, a high correlation between human skin and the biological skin equivalent is obtained. However, in contrast to bio-tribological studies, the friction experiments with biological tissue benefit from high reproducibility and low standard deviation. With the established test method the influence of state-of-the-art surface functionalization processes (chlorination and polymer-based coatings) and lubricants (cornstarch) on the friction properties of medical gloves is investigated in order to evaluate crucial process and surface parameters for low surface friction against human skin.

与人体皮肤接触的医用手套和皮肤等效物的摩擦学特性

摘要 新的表面改性技术在制造定制乳胶制品方面的进展面临着确定弹性体表面摩擦学性能的新表征技术的需求。因此，本研究旨在表征市售医用手套的摩擦性能，以评估其穿戴性能。摩擦测试方法的实验设计涉及手套样品在选定的对应材料上的线性运动。在第一步中，与小组一起进行生物摩擦学研究，从而能够客观地评估手套的穿戴特性。这些结果与手套对各种皮肤等效物（包括聚合物基材料、玻璃和生物组织）的摩擦系数进行了比较。在皮肤摩擦方面，获得了人体皮肤和生物皮肤等效物之间的高度相关性。然而，与生物摩擦学研究相比，生物组织的摩擦实验受益于高重现性和低标准偏差。使用既定的测试方法，研究了最先进的表面功能化工艺（氯化和聚合物基涂层）和润滑剂（玉米淀粉）对医用手套摩擦性能的影响，以评估关键工艺和表面参数。对人体皮肤的低表面摩擦。生物组织的摩擦实验得益于高重现性和低标准偏差。使用既定的测试方法，研究了最先进的表面功能化工艺（氯化和聚合物基涂层）和润滑剂（玉米淀粉）对医用手套摩擦性能的影响，以评估关键工艺和表面参数。对人体皮肤的低表面摩擦。生物组织的摩擦实验得益于高重现性和低标准偏差。使用既定的测试方法，研究了最先进的表面功能化工艺（氯化和聚合物基涂层）和润滑剂（玉米淀粉）对医用手套摩擦性能的影响，以评估关键工艺和表面参数。对人体皮肤的低表面摩擦。
