A Strong, Tough, and Self-Healing Strengthening Thioctic Acid-based Elastomerfor Highly Reliable Flexible Strain Sensor

Xinyu Chen, Yubing Fu, Xueling Yan, Lan Liu*

Abstract

Elastomers with high strength and toughness, excellent self-healing properties, and biocompatibility have broad application prospects in wearable electronics andother fields, but preparing it remains a challenge. In this work, we propose ahighly adaptable strategy by introducing the small molecule crosslinking agentof triethanolamine (TEA) to the poly thioctic acid (PTA) chains and preparingthe PAxEy elastomers using a simple synthesis step. Thisstrategy stabilizes the PTA chains by constructing multiple non-covalent cross-linked dynamic networks, endowing materials with excellent strength andtoughness (tensile strength of 288 kPa, toughness of 278.2 kJ/m3), admirable self-healing properties (self-healing efficiency of 121.6% within 7 h at 70 °C), and good biocompatibility. The PAxEy elastomers can also be combined with MWNTs to become flexible strain sensors, which can be used to monitor human joint movements with high sensitivity, repeatable responses, and stability.
