Construction of 3D aerogels consisting of cellulose and BNNSs bridged by AgNPs for enhancing thermal and tribological properties of polyurethane composites
Waterborne polyurethane (WPU) is attracting widespread attention in the friction field, but pure WPU cannot meet the wear resistance requirements due to poor thermal and self-lubricating properties.Herein, a novel cellulose/BNNSs-AgNPs aerogel (CBAg) composed of zero-dimensional silver nanoparticles (AgNPs), one-dimensional cellulose and two-dimens
