9461179 Bryant This Small Business Innovation Research Phase I will investigate using microencapsulated phase change materials (microPCMs) in a fabric layer as a thermal barrier to extend the endurance and productivity of underwater divers in cold water. MicroPCM-enhanced fabrics could be used alone (passively) or in conjunction with an auxiliary heating device (actively). For Phase I research purposed, the research emphasis will be on studying the effectiveness of a microPCM fabric as a thermal barrier in a diver's dry suit. However the concepts developed here will also apply to wet suits. Phase I objectives will be to: select, encapsulate and evaluate thermal properties of appropriate PCMS; acquire coated microPCM fabric samples and controls and evaluate their thermal properties; design laboratory tests to evaluate thermal performance of test fabrics; and evaluate thermal performance of test fabrics with and without auxiliary heating. The potential use of microPCM material to keep diver's comfortable and extend their work period will be thoroughly examined and recommendations made to the NSF for a follow-on Phase II effort.

这项小型企业创新研究的第一阶段将研究在织物层中使用微胶囊相变材料（microPCMs）作为热障，以延长水下潜水员在冷水中的耐力和生产力。微pcm增强织物可以单独使用（被动）或与辅助加热装置（主动）结合使用。对于第一阶段的研究目的，研究重点将是研究微pcm织物作为潜水员干服热障的有效性。然而，这里开发的概念也将适用于潜水服。第一阶段的目标是：选择、封装和评估合适的PCMS的热性能；获取涂层微pcm织物样品和控制，并评估其热性能；设计实验室测试，以评估测试织物的热性能；并对有无辅助加热的测试织物进行热性能评价。微pcm材料的潜在用途，以保持潜水员的舒适和延长他们的工作时间将被彻底检查，并向NSF提出建议，以进行后续的第二阶段工作。
