Resilient, Robust and Mechanical-Responsive Polydimethylsiloxane Composites Endowed by Interfacial Enhancement

Published: Jan. 1, 2025

The transition of material transparency induced by mechanical stimulation plays a crucial role in information encryption, anti-counterfeiting, and smart windows. However, developing multifunctional composite film that simultaneously possesses high elasticity sensitivity, low energy consumption, reusability remains significant challenge. In this work, homogeneous photonic crystal SiO2 were modified commercial available coupling agent KH570, enabling it to be chemically bonded the PDMS polymer networks, which enhanced interfacial interaction allowed periodic structure return its original state effectively both before after stretching. After undergoing 200 cycles testing, exhibited dissipation, with transmittance maintaining stability within range 90% 20%. At -50 °C, maximum loss factor was ~0.24, indicating retained resilience even under temperature. candidate for window supply only force. Furthermore, we adopted advanced imprinting technology, utilizing selectively designed molds embed arbitrary encrypted information. By controlling duration 5 seconds, 30 seconds 80 achieved differentiated displays same strain conditions on single film. Therefore, work can provide new insights into fields such as windows, sensing.
