软硬界面之间的界面热传输对于各种各样的能源应用至关重要，从复合材料、电池、热电和光子晶体到太阳热相变。在这个角度来看，我们讨论了主要的实验和模拟工具，用于研究这种界面的热传输，并总结了一些新的认识。大多数研究都集中在界面结合效应上，最近从分子水平理解了结合强度和热传输之间的潜在关系：更强的键吸引软分子更接近硬表面，这导致界面上更有效的能量传递。最近的研究还表明，振动光谱耦合是另一个重要的因素，影响热输运跨越硬-软界面，一个因素，长期以来一直低估了这样的接口。尽管这一领域取得了进展，但还需要更多的研究来...
Interfacial thermal transport across hard–soft interfaces is of critical importance to a wide variety of energy applications, ranging from composite materials, batteries, thermoelectrics, and photonic crystals to solar–thermal phase transition. In this Perspective, we discuss major experimental and simulation tools used to study such interfacial thermal transport and summarize some new understanding attained. Most studies focus on the interfacial bonding effect, and the underlying relation between bond strength and thermal transport was recently understood from the molecular level: stronger bonds attract soft molecules closer to the hard surface, which leads to more efficient energy communication across the interface. Recent studies have also demonstrated that vibrational spectral coupling is another important factor that influences thermal transport across hard–soft interfaces, a factor that has long been underappreciated for such interfaces. Despite the progress in this field, more research is needed to...
