Abstract

Abstract

En 中文
• Janus films integrate mica/h-BN & GnPs/MWCNTs for bifunctional thermal management. • Janus films enable dual-mode radiative cooling (7.24°C) and solar heating (10.46°C). • 3.Janus films presented an in-plane anisotropic thermal conductivity of 3.58 W·m−1·K−1. • Active-passive thermal synergy achieved through 4V-driven Joule heating (112.5°C). • Janus films demonstrated excellent thermal stability and aging resistance.
