Improved breathability and heat transfer of a microporous ePTFE membrane

消防员暴露在恶劣的条件下，包括火焰、闪火、重负荷、高水平的 心血管活动和高温这些综合作用可能导致热生理应激， 热应激热应激和热相关疾病是消防员伤亡的主要原因。针对这一 为了应对当前的挑战，必须开发更好的技术，以管理 在皮肤和防护服之间形成的微气候。其中一项战略是改善 防潮层的透气性、保护性制服中的防水中间层 防止热水和化学品。事实上，这种防潮层的存在限制了 身体湿气于是阻碍身体的蒸发冷却。我们提出了新的表面处理， 防潮层更亲水，以获得更高的水蒸气渗透性和透气性。

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.
