High‐Performance Low‐Emissivity Paints Enabled by N‐Doped Poly(benzodifurandione) (n‐PBDF) for Energy‐Efficient Buildings

Advanced Functional Materials, EarlyView.
This study introduces a scalable and colored low‐emissivity (low‐e) paint achieved by spraying an ultrathin n‐doped poly(benzodifurandione) (n‐PBDF) coating onto various colored substrates. The low‐e paint enhances thermal regulation by reducing mid‐infrared thermal emissivity to 0.19, thereby stabilizing indoor temperatures across diverse climates ...

Harnessing Outer Space for Improved Electrocaloric Cooling

Advanced Functional Materials, EarlyView.
A novel radiative heat sink/source‐integrated electrocaloric (R‐iEC) system combines the electrocaloric (EC) effect with a thermally conductive radiative cooler (TCRC) to address heat dissipation limitations in EC devices. Utilizing outer space as a heat sink, the system achieves up to 240 W m−2 of heat dissipation performance, making it highly ...
