Abstract

Integration of soft silicone materials through bonding is essential for the fabrication of soft robots and stretchable electronics. However, bonding of soft silicones is dependent on limited methods that compromise softness, structural integrity, and process simplicity. While plasma bonding is a fast and robust bonding method that overcomes these problems, it is limited to relatively rigid silicones, such as polydimethylsiloxane (PDMS). In this work, we propose a method for robust bonding of soft silicones through a simple and rapid process by introducing water to a plasma treatment. We found that water plasma bonding requires a short treatment time under 100 s to activate the surfaces and achieves interfacial toughness greater than 1,000 J m^–2 within 3 min of bonding. We demonstrate the potential of the proposed method through multiple applications in which the rapidness, robustness, and increased versatility in the choice of materials allow novel and efficient modes of fabricating soft devices.

软硅树脂的水等离子键合：快速和稳健的软器件制造

通过粘接将软硅材料集成在一起，对于制造软机器人和可拉伸电子产品至关重要。然而，软硅树脂的粘合依赖于有限的方法，这些方法会损害柔软性、结构完整性和工艺简单性。虽然等离子键合是一种快速而坚固的键合方法，克服了这些问题，但它仅限于相对坚硬的有机硅，如聚二甲基硅氧烷（PDMS）。在这项工作中，我们提出了一种通过将水引入等离子体处理的简单快速的方法来实现软硅酮的坚固粘合。我们发现，水等离子体键合需要在100秒以下的短时间内激活表面，并在键合后3分钟内达到大于1,000 J m-2的界面韧性。我们通过多种应用证明了所提出方法的潜力，在这些应用中，材料选择的快速，稳健性和增加的多功能性允许新的和有效的制造软器件的模式。
