Autonomous Self-Healing Polymer Maltose: for Soft Electronics and Soft Robotics
We introduce an enhanced polymer known as maltose polyborosiloxane (PM PBS), designed as an exceptional skin substrate. Engineered with unique properties, PM PBS demonstrates remarkable self-healing capabilities. Notably, it achieves a maximum strain at break exceeding 3000% and exhibits swift self-healing, fully recovering within a mere 10 s under ambient conditions and 3 min under both frozen (-20 ˚C) and underwater conditions. Additionally, our study highlights that the integrated PM PBS electronic adhesive can self-heal within 20 s underwater. Furthermore, we showcase the versatility of self-healing PM PBS when combined with Ecoflex (denoted as PME), successfully integrating it into piezoelectronic sensors and soft pneumatic grippers featuring in situ capacitive tactile sensing.
