Piezoresistive Natural Rubber Composites: A Comparison Between Low‐Temperature Glutaraldehyde Curing Agents and Conventional Sulfur Curing Systems

open access: yesPolymer Composites, Volume 47, Issue 5, Page 4310-4325, 10 March 2026.
The secondary electrical signal peak during cyclic experiment observed in S‐cured NR sensors was eliminated with GA curing due to the homogeneous distribution of crosslink points in the GA‐cured NR network. ABSTRACT This study examines the piezoresistive behavior of natural rubber (NR) composites cured with sulfur (S) and glutaraldehyde (GA) and ...
