Area of Science:

  • Materials Science
  • Sustainable Energy
  • Nanotechnology

Background:

  • Passive radiative cooling (RC) offers energy-free cooling below ambient temperature, crucial for energy savings and CO2 reduction.
  • Current RC surfaces often rely on energy-intensive fabrication or unsustainable materials, limiting widespread adoption.
  • Cellulose-based materials present a sustainable alternative, but require optimization for efficient radiative cooling performance.

Purpose of the Study:

  • To develop novel cellulose-based films for efficient passive radiative cooling.
  • To overcome limitations of energy-intensive fabrication and unsustainable materials in current RC technologies.
  • To demonstrate the adaptability of cellulose films for both above and below-ambient cooling applications.

Main Methods:

  • Fabrication of porous scattering films using cellulose acetate in two thicknesses (≈30 µm and ≈300 µm).
  • Characterization of optical properties, focusing on low solar absorptance and high mid-infrared emittance.
  • Field testing to evaluate cooling performance under varying environmental conditions, including solar absorption and heat loss minimization.

Main Results:

  • Developed cellulose films exhibit unprecedentedly low solar absorptance ( ) and strong mid-infrared emittance.
  • Achieved a net cooling power gain of at least 17 W m⁻², outperforming existing cellulose-based RC materials.
  • Demonstrated cooling up to ≈5 °C below ambient temperature, with potential for ≈7-8 °C under optimized dry conditions.

Conclusions:

  • Presents a simple, cost-efficient, and sustainable cellulose-based material for efficient passive radiative cooling.
  • Overcomes limitations of energy-intensive processes and polluting materials in conventional RC technologies.
  • Offers a viable alternative for passive cooling applications, contributing to energy conservation and environmental sustainability.
