Abstract：
The global climate change is mainly caused by carbon dioxide (CO2) emissions. To help reduce CO2 emissions and conserve thermal energy, sustainable materials based on flexible thermal insulation are developed to minimize heat flux, drawing inspiration from natural systems such as polar bear hairs. The unique structure of hollow double-shell fibers makes it possible to achieve low thermal conductivity in the material while retaining exceptional elasticity, allowing it to adapt to insulation systems of any shape. The layered system of porous mats reaches a thermal conductivity coefficient of 0.031 W∙m⁻¹∙K⁻¹ and enables to reduce the heat transfer. The results achieved using scanning thermal microscopy (SThM) correlate with the simulated heat flow in the case of individual fibers. This research study brings new insights into the energy efficiency of domestic environments, thereby addressing the growing demand for sustainable and high-performance insulation materials for saving energy loss and reducing pollution footprint.
摘要：
全球气候变化主要是由二氧化碳（CO2）排放引起的。为了帮助减少二氧化碳排放和节约热能，开发了基于柔性隔热的可持续材料，以最大程度地减少热通量，从北极熊毛等自然系统中汲取灵感。中空双壳纤维的独特结构使得在材料中实现低导热性，同时保持优异的弹性，允许它适应任何形状的绝缘系统。多孔垫的分层系统的导热系数达到0.031W·m-k-k-k，并能够减少热传递。在单个纤维的情况下，使用扫描热显微镜（SThM）获得的结果与模拟的热流相关。这项研究为国内环境的能源效率带来了新的见解，从而解决对可持续和高性能绝缘材料日益增长的需求，以节省能源损失并减少污染足迹。
