Oct 12, 2020 · Herein, two thermal management strategies based on boron nitride (BN) aerogel films have been proposed and demonstrated for portable devices. First, a flexible BN aerogel film with high porosity (>96%), large specific surface area (up to 982 m 2 g –1 ), and controllable thickness (in the range from 50 to 200 μm) was fabricated via molecular ...
