Highly Stretchable, Ultra-Soft, and Fast Self-Healable Conductive Hydrogels Based on Polyaniline Nanoparticles for Sensitive Flexible Sensors

Xiaohui Yu et al.

Summary: In this study, novel conductive composite hydrogels with high stretchability, ultra-softness, excellent conductivity, and good self-healing ability were developed. The hydrogels were formed by incorporating polyaniline nanoparticles (PANI-NPs) into poly(poly(ethylene glycol) methacrylate-co-acrylic acid) (P(PEG-co-AA)) scaffolds through dynamically electrostatic interactions and hydrogen bonds. The PANI-NPs served as conductive fillers, while the enhanced interactions between PANI-NPs and P(PEG-co-AA) matrix imparted high stretchability, low modulus, excellent elasticity, and fast self-healing ability to the hydrogel. The introduction of a binary solvent system also allowed for ideal anti-freezing properties. Composite hydrogel-based sensors were proposed, demonstrating states-independent properties, low detection limit, high linearity, and excellent anti-fatigue performance.
