Planting Carbon Nanotubes onto Supramolecular Polymer Matrixes for Waterproof Non-Contact Self-Healing

Abstract

Supramolecular polymers show unique and excellent properties due to the reversible and designable nature of the noncovalent interactions. Herein, the ureido-pyrimidinone (UPy)-based supramolecular polymers were employed to fabricate thermo-responsive composite materials with the multi-walled carbon nanotubes (MWCNTs) by planting the MWCNTs onto the supramolecular polymer matrixes via a simple surface spraying procedure. The MWCNTs coating on the surface of the supramolecular polymer matrixes gave the composite film superhydrophobic and conductive properties and had non-contact healable ability underwater under 808 nm near-infrared light (NIR) irradiation. Meanwhile, the UPy-based supramolecular polymers acted as thermo-responsive matrixes to guarantee the self-healing properties at a relatively low temperature, such as body temperature (33-34°C). The supramolecular polymer/MWCNTs composite materials exhibited excellent strain sensitivities and could be used to prepare human motion monitoring devices. This line of research may find promising practical application for healable wearable devices used in underwater environments.
