Abstract: Microfiber materials are widely used in the field of flexible packaging with both the printability and processability of paper, and the barrier and laminating properties of film, there is a key problem common to the field of flexible packaging materials and safety textiles: how to effectively reduce the internal temperature of the package to ensure the safety of materials. Based on this, this work proposes to introduce silicon dioxide (SiO2) into poly lactic acid/poly ethylene glycol (PLA/PEG) blending system, then prepare PLA/PEG@SiO2 microfiber material by melt blown, and test its physical structure, mechanical properties and radiative cooling properties. The results show that SiO2 has a positive effect on the nucleation and crystallization of PLA, which can effectively improve the crystallization behavior of PLA; SiO2 particles can be loaded on the fiber surface, which effectively improves the surface roughness (Sa) of the fibers; and as the mass ratio of SiO2 is increased to 2.5%, the average diameter of the fibers increases to 7.11 μm, and the surface roughness increases to 12.7 μm. Benefit from the above microfiber structure characteristics of microfiber material samples emissivity and reflectivity up to 87.5% and 98.1%, the test temperature difference of up to 8.9 ℃, with excellent daytime radiation cooling performance. In addition, the PLA/PEG@SiO2 microfiber material exhibits excellent shielding performance against liquids such as water, tea and coffee, exhibit good printability and shaped cutability, which is expected to provide a new flexible fiber material for daytime radiative cooling in the fields of flexible packaging and outdoor sports.
