Sustainable Radiative Cooling of Microstructure Modulated Flexible poly(lactic Acid) Films.

The optimization of polymer microstructures to enable resonant light scattering within the solar spectrum offers significant potential for passive cooling, however, achieving precise microstructural control remains technically challenging. Herein, we present a strategy for fabricating polylactide radiative cooling film with adjustable microstructure. The surface pore structure and internal spherical structure of the film are precisely controlled by polyethylene glycol, which in turn modulates the film's optical properties.

Template-Thermally Induced Phase Separation-Assisted Microporous Regulation in Poly(lactic acid) Aerogel for Sustainable Radiative Cooling.

Herein, an eco-friendly and degradable poly(lactic acid) aerogel was prepared by combining a poly(ethylene glycol) template material with thermally induced phase separation. Due to the tailored pore size introduced by the template material, the aerogel exhibits high solar reflectance (92.0%), excellent thermal emittance (90.

Review on Cell Structure Regulation and Performances Improvement of Porous Poly(Lactic Acid).

Recent advances in the cell structure regulation and performances improvement of porous poly(lactic acid) materials (PPMs) are systematically reviewed in this feature article. First, the typical processing methods, including template method, non-solvent induced phase separation, freeze-drying, and supercritical CO  foaming, of PPMs are introduced emphatically. Their various cell morphologies by different processing methods are summarized: finger-like, honeycomb-like, fiber-like, through cell, open cell, closed cell, ball-like, and flower-like.
