China University of Science and Technology: superelastic and fatigue-resistant carbon nanofiber aerogels resistant to temperature changes
YU Shuhong, LIANG Haiwei and colleagues at the University of Science and Technology of China have reported a method for thermally transforming bacterial cellulose into graphitic carbon nanofiber aerogels (CNFAs) through controlled pyrolysis. The carbon aerogel is based on the hierarchical structure of bacterial cellulose, and maintains superelasticity without plastic deformation after 2 × 106 compression cycles. It shows excellent superelasticity and fatigue resistance that do not change with temperature betweens -100 to 500 ° C.
