Skin adhesives are polymer materials used for attaching medical devices to the skin. Probing the performance of such adhesives is of great interest for rational material formulation. Here, we present a perspiration simulator, which includes a skin mimicking gelatin substrate with controlled roughness and the ability to perspire with a tunable sweat rate. The setup was used for probing peel adhesion of adhesives under realistic wear conditions. Adhesives with indistinguishable rheological properties but different ability to absorb artificial sweat were evaluated. The rheological properties were fixed to decouple the bulk mechanical properties from events occurring at the substrate–adhesive interface. The effects of application pressure, dwell time, and perspiration were quantified for each adhesive formulation. Here, we found that sweat introduced at the substrate–adhesive interface restricts further bonding of the adhesives by limiting viscous flow. Water-absorbing skin adhesives were found to have significantly higher peel forces compared to nonabsorbing adhesives under sweating conditions where the adhesive could absorb the introduced sweat.

高分子皮肤胶在汗液中的性能
皮肤粘合剂是用于将医疗设备附着到皮肤上的聚合物材料。对于合理的材料配方，探索此类粘合剂的性能非常重要。在这里，我们介绍了一种排汗模拟器，包括模拟皮肤的明胶基质，其粗糙度可控，并且能够以可调的出汗率排汗。该装置用于在实际磨损条件下探测粘合剂的剥离粘合力。评估了具有无法区分的流变特性但吸收人造汗液的能力不同的胶粘剂。固定了流变性能，以使整体机械性能与基材-粘合剂界面处发生的事件脱钩。对于每种粘合剂制剂，量化了施加压力，保压时间和汗水的影响。这里，我们发现，在基材-粘合剂界面处引入的汗液通过限制粘性流动而限制了粘合剂的进一步粘合。发现在出汗条件下吸水皮肤粘合剂与不吸收粘合剂相比具有显着更高的剥离力，在出汗条件下粘合剂可以吸收引入的汗水。
