HIGH-PERFORMANCE SUB-AMBIENT RADIATIVE COOLING ENABLED BY OPTICALLY SELECTIVE AND THERMALLY INSULATING POLYETHYLENE AEROGEL

摘要

Recent progress in passive radiative cooling technologies have significantly improved cooling performance under direct sunlight. Performance of existing passive radiative coolers for air conditioning and portable refrigeration applications can be improved with a material that is solar reflective and infrared transparent that can also have a low thermal conductivity.
