DESCRIPTION (provided by applicant): The Phase I work has demonstrated the fabrication of a thin, strong, lightweight composite material that could be scaled up from the laboratory to industrial pilot quantities. The phase I material shows no breakthrough flux of mustard and nerve agents (HD and GB) (actual chemical warfare agents) for over 48 hrs, which exceeds the current 8hrs criteria for suits, as verified by an Army certified laboratory. The composition presents a powerful self-decontaminating, triple defense concept- Chemical agent deactivation, barrier effect and biocidal effect. In addition the material is moisture vapor permeable (breathable) but not air permeable. The biocidal activities of the composites against Anthrax surrogate Bacillus var. niger spores and Anthrax spores were firmly established. Typically 4-5 log reductions (total kill) were noted when the samples were exposed to Anthrax, Bacillus spores and other pathogens. The capacity to kill over 70 million anthrax spores! 50 cm2 of the phase I material was recorded. The phase II would concentrate on optimizing the assembly of the membrane to an outer shell fabric. The optimization of the thickness, composition, and production parameters will be done. Quantitative kill kinetic curves for aerosolized Anthrax spores and certain viral and bacterial species will be established. The deactivation of chemical agent kinetics and resistance to aerosol penetration will be demonstrated. A reputable team of experts from the Army laboratories and textile industry has been assembled to carry out all the qualifying tests for such a material. The protection factor offered by these suits will be characterized by the Army materials laboratory. Commercial partners have been identified. PROPOSED COMMERCIAL APPLICATIONS: The market size for the protective clothing for civilians, police, medical personnel and fire fighters for domestic preparedness is expected to be 2 billion dollars by year 2004. ICET's market share is estimated to be about 200 million dollars five years after commercial entry.

描述（由申请人提供）：第一阶段的工作已经证明了薄，强，轻质复合材料的制造，可以从实验室扩大到工业试验量。第一阶段的材料显示，在超过48小时的时间里，芥子气和神经毒剂（HD和GB）（实际的化学战剂）没有突破性的通量，这超过了陆军认证实验室目前对西装的8小时标准。 该组合物具有强大的自去污、三重防御概念-化学剂失活、屏障效应和杀生物效应。此外，该材料是湿气可渗透的（可透气的）但不是空气可渗透的。研究了复合材料对炭疽芽孢杆菌的生物杀灭活性。尼日尔孢子和炭疽孢子牢固建立。当样品暴露于炭疽、芽孢杆菌孢子和其他病原体时，通常观察到4-5个对数减少（总杀灭）。它有能力杀死七千万炭疽孢子！记录50 cm 2的相I材料。 第二阶段将集中于优化膜与外层织物的组装。将进行厚度、成分和生产参数的优化。将建立雾化炭疽孢子和某些病毒和细菌种类的定量杀灭动力学曲线。化学剂动力学和抵抗气溶胶渗透的失活将被证明。来自陆军实验室和纺织工业的一个信誉良好的专家小组已经组建起来，对这种材料进行所有合格测试。这些防护服所提供的防护系数将由陆军材料实验室进行表征。商业伙伴已经确定。 拟议的商业应用： 预计到2004年，平民、警察、医务人员和消防队员的国内防护服市场规模将达到20亿美元。ICET的市场份额预计在进入商业市场5年后约为2亿美元。
