Article: Preparation and performance of supramolecular polymer-based piezoresistive damping composites Journal: International Journal of Materials and Product Technology (IJMPT) 2026 Vol.70 No.6 pp.123 - 145 Abstract: This paper proposes a collaborative construction strategy based on molecular design and multi-scale structure tuning to address the main conflict between high damping efficiency and sustainable piezoresistive response in supramolecular polymer based piezoresistive damping composites. Firstly, this paper constructs a dynamically reversible thermoplastic polyurethane matrix by introducing a quadruple hydrogen bond UPy (2-ureido-4 [1H] - pyrimidinone) unit, and controls the hydrogen bond density to optimise the internal friction ability. Secondly, this paper proposes a heterogeneous mixed filler composed of aminated SiO<SUB align="right"><SMALL>2</SMALL></SUB> (silicon dioxide) and carboxylated multi walled carbon nanotubes. Finally, this paper prepares a series of composite materials through solution mixing hot pressing process, and predicts the synergistic window of electromechanical properties using an improved percolation Maxwell model. The results showed that the prepared composite material had a mixed filler content of 5 wt%, a peak damping loss factor of 0.83, and a piezoresistive sensitivity of 12.4.
