基于聚二甲基硅氧烷（PDMS）的有机-无机杂化材料由于其高的介电强度、耐热性和柔性而被研究。在这项研究中，我们制作了Al 2 O3涂层的金属基板上具有足够的电绝缘性，导热性和热稳定性的电泳沉积（EPD）使用基于PDMS的混合粘合剂。Al 2 O3涂层在300 ℃热处理500 h前后的划痕硬度、热导率和电击穿强度分别为2.0 N、3.1 W/mK和60 kV/mm。这些结果证明了使用基于PDMS的混合粘合剂的EPD用于制造在高温环境中使用的柔性散热基板的有用性。
Polydimethylsiloxane (PDMS)-based organic-inorganic hybrids have been studied because of their high dielectric strength, heat resistivity, and flexibility. In this study, we fabricated Al2O3 coatings on metal substrates with sufficient electrical insulation, heat conductivity, and thermal stability by electrophoretic deposition (EPD) using PDMS-based hybrid binders. The scratch hardness, thermal conductivity, and electrical breakdown strength of the Al2O3 coating before and after heat treatment at 300 °C for 500 h were 2.0 N, 3.1 W/mK, and 60 kV/mm, respectively. These results demonstrate the usefulness of EPD using PDMS-based hybrid binders for fabricating flexible heat dissipative substrates used in high-temperature environments.
