<p>Current protective clothing often lacks sufficient comfort to ensure efficient performance of healthcare workers.

摘要

Current protective clothing often lacks sufficient comfort to ensure efficient performance of healthcare workers. Developing protective textiles with high air and moisture permeability is a potential and effective solution to discomfort of medical protective clothing. However, realizing the facile production of a protective textile that combines safety and comfort remains a challenge. Herein, we report the fabrication of highly permeable protective textiles (HPPT) with micro/nano-networks, using non-solvent induced phase separation synergistically driven by CaCl2 and fluorinated polyurethane, combined with spraying technique. The HPPT demonstrates excellent liquid repellency and comfort, ensuring high safety and a dry microenvironment for the wearer. The textile exhibits not only a high hydrostatic pressure (12.86 kPa) due to its tailored small mean pore size (1.03 μm) and chemical composition, but also demonstrates excellent air permeability (14.24 mm s−1) and moisture permeability (7.92 kg m−2 d−1) owing to the rational combination of small pore size and high porosity (69%). The HPPT offers superior comfort compared to the commercially available protective materials. Additionally, we elucidated a molding mechanism synergistically inducted by diffusion–dissolution-phase separation. This research provides an innovative perspective on enhancing the comfort of medical protective clothing and offers theoretical support for regulating of pore structure during phase separations.
