摘要
相变微胶囊(Microcapsule phase change materials,MPCM)是通过微胶囊化技术将相变材料包裹制备而成的,能够储存或释放大量热能,在许多领域具有良好的应用前景。但MPCM在实际应用中仍存在导热性能较差等问题,严重限制了其应用,因此越来越多的微胶囊导热改性方法被研究,用于制备导热性能增强的MPCM。本文通过阐述Pickering乳液、表面接枝、化学镀层和物理掺杂等改性方法的原理与特点,总结了微胶囊壳材导热改性方法,并概述了微胶囊在调温领域的相关进展。最后,展望了MPCM壳材导热改性的研究方向以及其在调温领域的未来前景与挑战。
Microcapsule phase change materials(MPCM)are prepared by encapsulating phase change materials through microencapsulation technology and are capable of storing or releasing large amounts of thermal energy,which have good application prospects in many fields.However,MPCM still have problems in practical applications such as poor thermal conductivity which seriously limits their applications.So more and more microcapsule thermal conductivity modification methods have been studied to enhance thermal conductivity.This paper summarized the thermal conductivity modification methods of microcapsule shells by describing the principles and characteristics of modification methods such as Pickering emulsion,surface grafting,chemical plating and physical doping.And the relevant progress of microcapsules in the fields of thermoregulation was introduced.Finally,the research direction was mentioned for MPCM of shells thermal conductivity modification,and the future prospects of phase change microcapsules in the fields of thermoregulation were envisioned.
