摘要

Stretchable conducting polymer nanocomposites are indispensable for designing flexible electronic devices mainly employed in emerging robotic technology to improve human–machine interactions. Herein, we report the fabrication and testing of 300% stretchable electronic film resistors as strain sensors by spray coating carbon nanofibers (CNFs)/natural rubber solutions over a stretchable acrylic latex-CNF nanocomposite substrate. The CNF-based coatings had a low sheet resistance of 26 Ω sq−1 and very good current transmission behaviour under elongation. Under 300% elongation, the nanocomposite film current reached ~55 µA demonstrating their potential as flexible thin conductive films.
