SBIR Phase I: CAS: Climate-Eco-friendly Biocoating for Passive Cooling of Infrastructure

这个小企业创新研究（SBIR）第一阶段项目的更广泛/商业影响是寻求使用创新的被动冷却技术来减少全球变暖。该项目将开发一种环保的被动式冷却涂层，可以帮助降低建筑物的温度。根据气候和建筑特点，这种涂层预计可以减少5-25%的能源消耗。该解决方案可能会减少对传统的基于压缩机的冷却系统（例如空调）的需求，这些系统需要持续的电力和冷却剂供应，从而通过温室效应对环境造成压力。该公司希望通过具有生物相容性的被动冷却纤维和原羟基磷灰石（HAP）纤维的类油漆涂层产生商业收入。涂料矩阵的主要客户目标群体包括商业和住宅建筑业主，他们正在寻找降低电费的方法，同时减少对环境的负面影响。提出的创新是建立在自清洁，防火，冷却纤维与HAP配制。HAP冷却纤维将集成在涂料基体中，以便于应用和成本效益。目的是开发和商业化这种环保，被动冷却材料作为涂层具有多种功能。该团队将在成本限制下确定环保的涂料基材料，确定涂料与纤维的相容性，并验证候选复合材料的冷却性能。涂料材料的耐久性也将得到确认。该项目将重点设计一条能够在中试规模上生产纤维基冷却涂料的小规模生产线，以实现可重复性和现场验证。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

The broader/commercial impact of this Small Business Innovation Research (SBIR) Phase I project seeks to reduce global warming using an innovative passive cooling technique. The project will develop an environmentally friendly, passive cooling coating that can help reduce the temperature of buildings. The coating is expected to provide energy reductions ranging from 5-25%, depending on climate and building characteristics. The solution may reduce the need for traditional compressor-based cooling systems (e.g., air conditioners), which require a constant supply of electricity and coolants, stressing the environment through the greenhouse effect. The company expects to generate commercial revenues from both the paint-like coating featuring biocompatible passive cooling fibers and raw hydroxyapatite (HAP) fibers. Main customer target groups for the paint matrix include commercial and residential building owners that are looking for ways to lower their electric bills while lessening their negative environmental footprint.The proposed innovation is founded on self-cleaning, fire-resistant, cooling fibers formulated with HAP. HAP cooling fibers will be integrated within a paint matrix for ease of application and cost-effectiveness. The aim is to develop and commercialize this environmentally friendly, passive cooling material as a coating with multiple functionalities. The team will identify environmentally friendly, paint-based materials within cost constraints, determine paint-fiber compatibility, and validate the cooling performance of candidate composites. The durability of the paint materials will also be confirmed. The project will focus on the design of a small-scale manufacturing line capable of producing fiber-based cooling paint at pilot scale for repeatability and field validation.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
