The photothermal phenomenon involves material photon heating in the form of continuous waves, modulated or pulses. resulting temperature rise carries very rich information about material's structures and thermophysical properties. This review is constructed to cover some extended ideas for measuring a properties interface thermal conductance/resistance. For frequency-domain phenomena, photoacoustic (PA) radiation (PT) techniques provide great ways measure coatings suspended samples, which...
Conventional polymer composites normally suffer from undesired thermal conductivity enhancement which has hampered the development of modern electronics as they face a stricter heat dissipating requirement. It is still challenging to achieve satisfactory with reasonable mechanical properties. Herein, we present three-dimensional (3D), lightweight, and mechanically strong boron nitride (BN)-silicon carbide (SiC) skeleton aligned pathways via combination ice-templated assembly high-temperature...
High-thermal-conductivity polymers are very sought after for applications in various thermal management systems. Although improving crystallinity is a common way increasing the conductivity (k) of polymers, it has limited capacity when already high. In this work, by heat-stretching highly crystalline microfiber, significant k enhancement observed. More interestingly, coincides with reduction crystallinity. The sample Spectra S-900 ultrahigh-molecular-weight polyethylene (UHMW-PE) microfiber...
Tungsten–graphene multilayer composites are fabricated using a stacking method. The thermal resistance induced by the graphene interlayer is moderate. An ion-implantation method used to verify radiation tolerance. results show that inserted among tungsten films plays dominant role in reducing damage. Furthermore, performance of different period-thicknesses tolerance systematically analyzed. As service our authors and readers, this journal provides supporting information supplied authors....
This work uncovers that free-standing partly reduced graphene aerogel (PRGA) films in vacuum exhibit extraordinarily bolometric responses. high performance is mainly attributed to four structure characteristics: extremely low thermal conductivity (6.0-0.6 mW·m-1·K-1 from 295 10 K), porosity, ultralow density (4 mg·cm-3), and abundant functional groups (resulting tunable band gap). Under infrared radiation (peaked at 5.8-9.7 μm), the PRGA film can detect a temperature change of 0.2, 1.0, 3.0...
Abstract With the rapid development of electronic information technology in 5G era towards high integration, short propagation delay, and elevated assembly temperatures, more academic industrial attention has been focused on high-frequency high-speed copper-clad laminates (CCLs). Compared with conventional polymeric matrices, thermoset polyphenylene oxide (PPO) become one most attractive resins applied high-performance CCLs (HPCCLs) because its excellent comprehensive properties, including...
Probing the ideal limit of interfacial thermal conductance (ITC) in two-dimensional (2D) heterointerfaces is paramount importance for assessing heat dissipation 2D-based nanoelectronics. Using graphene/hexagonal boron nitride (Gr/$h$-BN), a structurally isomorphous heterostructure with minimal mass contrast, as prototype, we develop an accurate yet highly efficient machine-learned potential (MLP) model, which drives nonequilibrium molecular dynamics (NEMD) simulations on realistically large...
Polymer-based thermal interface materials (TIMs) are indispensable for reducing the contact resistance of high-power electronic devices. Owing to low conductivity polymers, adding multiscale dispersed particles with high is a common approach enhance effective conductivity. However, optimizing particle matching, including size distribution and volume fraction, improving has not been achieved. In this study, three kinds filler-loaded samples were prepared, average tested. The finite element...
Interfacial binding and phonon mismatch are two crucial parameters in determining thermal boundary conductance. However, it is difficult for polymer/metal interfaces to possess both significant interfacial weak achieve enhanced Herein, we circumvent this inherent trade-off by synthesizing a polyurethane thioctic acid (PU-TA) copolymer with multiple hydrogen bonds dynamic disulfide bonds. Using PU-TA/aluminum (Al) as model interface, demonstrate that the conductance of PU-TA/Al measured...
Small molecules with functional groups can show different electron affinity and binding behavior on nanocrystal surface, which in principle could be used to alternate the electrical transport self-assembled thin films. These small also serve for scattering phonons reduce thermal conductivity. Here, we present our research thermoelectric characteristic of silver telluride (Ag2Te) films that are fabricated by a layer-by-layer (LBL) dip-coating process. We perform investigations conductivity...
