Our concept concerns the development of an innovative high performance thermal insulation material that offers thermal conductivity and density approaching that of aerogels but at a cost that competes with PU and EPS foams. Polymer foam insulation such as polyurethane and expanded polystyrene (e.g. Styrofoam) is made by expanding the polymer with a blowing agent to produce a foam with relatively large cells that contain the low conductivity gas blowing agent. As the gas migrates out of the cells over time, the foam ages and the insulation performance falls. We will develop a polymer foam by a templating method to manufacture an insulation material with careful control of porosity and cell size distribution whilst eliminating the use of blowing agents; low thermal conductivity is achieved by high porosity and small cell size only. Proving the concept of the technology for enhanced thermal insulation manufacture will lead to a breakthrough innovation in the cost-effective and competitive production of high performance, blowing agent-free polymer foam thermal insulation material that can be used in a number of sectors where enhanced, reliable, low-cost thermal insulation is required, including refrigerated transport, construction, and hot water storage.

我们的理念是开发一种创新的高性能隔热材料，其导热性和密度接近气凝胶，但成本与PU和EPS泡沫竞争。聚合物泡沫绝缘体如聚氨酯和发泡聚苯乙烯（例如聚苯乙烯泡沫）是通过用发泡剂使聚合物膨胀以产生具有相对大的泡孔的泡沫来制备的，所述泡孔包含低电导率气体发泡剂。随着气体随着时间从泡孔中迁移出来，泡沫老化，绝缘性能福尔斯下降。我们将通过模板法开发一种聚合物泡沫，以制造一种绝缘材料，该材料具有仔细控制的孔隙率和泡孔尺寸分布，同时不使用发泡剂;仅通过高孔隙率和小泡孔尺寸实现低导热性。证明增强隔热制造技术的概念将导致具有成本效益和竞争力的高性能无发泡剂聚合物泡沫隔热材料生产的突破性创新，该材料可用于需要增强，可靠，低成本隔热的许多部门，包括冷藏运输，建筑和热水储存。
