摘要

安全、绿色、高效的工业生产一直是化工行业的追求。由于热能是大多数化学反应的驱动力,理想的反应罐应该具有自动调节热传导速率的能力。详细地说,当反应温度低于目标时,该反应罐应具有抵抗热损失的能力,同时在系统过热时加速散热。在这种情况下,这种智能反应堆不仅可以最大限度地减少能源消耗,还可以降低安全风险。已知中空结构会降低导热性。特别地,具有多壳体的中空结构可以提供更多的界面,从而进一步抑制热传递,这将更有利于隔热。接下来,通过将HoMS与温度敏感聚合物耦合,本工作制备了一种智能隔热材料。它在相对较低的温度下起到良好的隔热作用。厚度为1 mm的TSPU/3S–TiO2 HoMS在50°C的温度场下可以达到6.5°C的隔热效果。在过热条件下,复合材料的导热系数会提高。此外,这种复合材料在加热过程中表现出不同寻常的两阶段相变。得益于独特的多壳结构,能量被逐渐引导到中空结构中并储存在内部。这种局部热量积累使该复合材料成为智能热调节器和现场定义微反应器的潜在涂层材料。

Smart heat isolator with hollow multishelled structures

Smart heat isolator with hollow multishelled structures

Safe, green and efficient industrial production has always been the pursuit of the chemical industry. Since thermal energy is the driving force for most of chemical reactions, an ideal reaction tank would have the capacity to automatically regulate heat conduction rate. In detail, this reaction tank should endow an ability that resists the heat loss when the reaction temperature is lower than the target, while accelerating the heat dissipation when the system is overheated. In this case, this smart reactor can not only minimize energy consumption but also reduce safety risks. Hollow structures are known to reduce heat conductivity. Particularly, the hollow structure with multishells can provide more interfaces and thus further inhibit heat transmission, which would be more favorable for heat isolation. Step forward, by coupling HoMSs with temperature-sensitive polymer, a smart heat isolation material has been fabricated in this work. It performs as a good heat isolator at a relatively lower temperature. A heat insulation effect of 6.5 °C can be achieved for the TSPU/3S–TiO2 HoMSs with a thickness of 1 mm under the temperature field of 50 °C. The thermal conductivity of composite material would be raised under overheating conditions. Furthermore, this composite displays an unusual two-stage phase transformation during heating. Benefiting from the unique multishelled structure, energy is found to be gradually guided into the hollow structure and stored inside. This localized heat accumulation enables the composite to be a potential coating material for intelligent thermal-regulator and site-defined micro-reactor.
