Tunable Electrical and Fatigue Performance of Carbon Nanotube-Embedded Bottlebrush Elastomers via Compositional Control

Year: 2025

Type: article

Abstract: Bottlebrush elastomers (BBEs) are promising for flexible and wearable electronics due to their mechanical resilience. Incorporating conductive nanofillers such as carbon nanotubes (CNTs) enables the tuning of their electrical properties. This work studies the electrical properties of CNT–bottlebrush elastomer composites by varying polydimethylsiloxane (PDMS)/crosslinker ratios and CNTs loadings. Building on established synthesis methods, this study investigates how compositional changes affect conductivity, sensitivity, and fatigue behavior. Our results show a composition-dependent trade-off between electrical and mechanical fatigue performance, offering insights into tailoring these composites to meet specific performance requirements in next-generation soft electronics.
