Improved breathability and heat transfer of a microporous ePTFE membrane

消防员暴露在严重的条件下，包括火焰，闪光，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。热应激和热相关疾病是消防员伤亡的主要原因。为了应对当前的这一挑战，重要的是要开发更好的技术，以管理皮肤和防护服之间产生的微气候中的热量积聚。其中一个策略是提高防潮层的透气性，防潮层是保护制服中的防水中间层，可以防止热水和化学品。事实上，这种水分屏障的存在限制了身体水分的排出，然后阻碍了身体的蒸发冷却。我们提出了新的表面处理，使 ** 防潮层更亲水，以获得更高的水蒸气渗透性，从而透气。

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.
