Tóm tắt

Passive Radiant Cooling and Heating are green and sustainable methods of radiant heat management without consuming additional energy. However, the absorption of sunlight and poor insulation of materials can reduce radiative cooling and also affect radiative heating performance. Herein, we have constructed porous hierarchical dual-mode silk nanofibrous aerogel (SNF) films with high mechanical toughness and stability using silk nanofibers/GO. The porous hierarchical structure endows the cooling side of the dual-mode film with low thermal conductivity (0.034 W·m
