DESCRIPTION: Protective clothing is one of the most important personal protective equipment for emergency responders, who are facing increased occupational threats in their high risk jobs. However, currently used protective clothing has significant shortfalls, including the lack of multiple-purpose protective clothing, the unsatisfactory protective performance, and the tradeoff between protection and comfort. The long term goal of this project is to develop novel wearable thermal, biological, and chemical protective clothing materials with enhanced comfort performance for emergency responders. To reach this goal, currently used thermal protective fabrics (Nomex, Kevlar, and PBI) will be chosen as the base material, and a coating technology will be employed to coat reusable and rechargeable polymeric oxidizers onto the base fabrics through breathable flame-retardant coatings containing chemical absorbents. The specific aims of the proposed research are to: (1) screen reusable and rechargeable polymeric oxidizers that can effectively decontaminate surrogates of biological and chemical warfare agents; (2) establish the optimal formulations and technologies to coat the selected polymeric oxidizers onto thermal protective fabrics through breathable flame-retardant coatings containing chemical absorbents; (3) evaluate the thermal protective, biological protective and chemical protective functions, the mechanical properties, as well as the comfort performance of the new fabrics; and (4) collect preliminary data to determine the cost of the new approach. These specific aims are designed to demonstrate the concept that wearable multi-purpose protective clothing can be developed to provide thermal, biological, and chemical protective activities simultaneously. This R03 research will serve as an important base for the continuation and expansion of the project to improve the occupational safety and health of emergency responders.

描述：防护服是紧急响应者最重要的个人防护设备之一，他们在高风险工作中面临越来越多的职业威胁。但是，目前使用的防护服具有明显的缺口，包括缺乏多功能防护服，不令人满意的保护性能以及保护和舒适之间的权衡。该项目的长期目标是开发新型的可穿戴热，生物和化学保护服装材料，并为紧急响应者增强舒适性能。为了实现这一目标，将选择当前使用的热保护织物（Nomex，Kevlar和PBI）作为基础材料，并将采用涂料技术通过透气的耐燃烧火焰涂层含有含有化学吸收的化学吸收者，将可重复使用的可重复使用和可充电的聚合物氧化剂涂在基础织物上。拟议的研究的具体目的是：（1）可重复使用和可充电的聚合物氧化剂，可以有效地净化生物和化学战剂的替代物； （2）建立最佳的配方和技术，通过透气的耐燃料涂层含有化学吸收剂，将所选聚合物氧化剂涂在热保护织物上； （3）评估热保护性，生物保护和化学保护功能，机械性能以及新织物的舒适性能； （4）收集初步数据以确定新方法的成本。这些特定目标旨在证明可以开发可穿戴多功能保护服的概念，以同时提供热，生物学和化学保护活动。这项R03研究将成为继续和扩展该项目以改善紧急响应者职业安全和健康的重要基础。
