Li/Al-LDH Reinforced Polyacrylamide/Xanthan Gum Semi-Interpenetrating Network Nano-Conductive Hydrogels for Stress Sensing and Wearable Device Applications.

ABSTRACT: Layered double hydroxides (LDHs) have gained significant attention for their unique physicochemical properties, but their application in conductive hydrogels for strain-sensing still remains rarely explored due to their low electrical conductivity and poor compatibility with the hydrogel network. This study proposes an innovative strategy of preparing highly conductive and mechanically robust Li/Al-LDH reinforced polyacrylamide (PAM)/xanthan gum (XG) semi-interpenetrating network nano-conductive hydrogels (PXL) by in situ polymerization of acrylamide (AM) monomers in Li/Al-LDH colloidal solution. Li/Al-LDH exhibits high electrical conductivity and meanwhile interacts with the polymer matrix to form coordination/hydrogen bonds. The unique multi-collaborative network endows the PXL hydrogel
