Improved breathability and heat transfer of a microporous ePTFE membrane

消防员面临的严酷环境包括火焰、火苗、重负荷、高水平的心血管活动和极端高温。这些综合作用可能导致热生理应激和热应激。热应激和与热有关的疾病是消防员伤亡的主要原因。为了应对当前的挑战，开发更好的技术来控制皮肤和防护服之间产生的微气候中的热量积聚是很重要的。其中一个策略是提高防潮层的透气性，这是防护服中的防水中间层，可以防止热水和化学物质的侵害。事实上，这种水分屏障的存在限制了身体水分的排出，从而阻碍了身体的蒸发冷却。我们提出了新的表面处理，使**的防潮层更亲水，以获得更高的透气性和透气性。

Firefighters are exposed to severe conditions including flames, flash fire, heavy load, high level of**cardiovascular activity and extreme heat. These combined effects may lead to thermophysiological stress and**heat stress. Heat stress and heat-related illness are major causes of casualties for firefighters. In response to this**current challenge, it is important to develop better technologies in order to manage heat build-up in the**micro-climate created between the skin and the protective uniform. One of the strategies consists of improving**the breathability of the moisture barrier, the waterproof intermediate layer in the protective uniform that**protects against hot water and chemicals. In fact, the presence of this moisture barrier limits the evacuation of**the body moisture then impedes evaporative cooling of the body. We propose new surface treatments to render**the moisture barrier more hydrophilic in order to obtain higher water vapor permeability and so breathability.
