摘要: 采用点击化学反应在UiO-66-NH2膜表面原位生长硅油润滑层,制备了金属有机框架(MOF)基防冰膜(OGMCs),通过硅油生长时间调控了表面硅油量,并对不同硅油含量的OGMC的防冰性能进行了研究。 利用扫描电子显微镜(SEM)、傅里叶变换红外光谱仪(FT-IR)、X射线衍射仪(XRD)、X射线光电子能谱分析仪(XPS)和接触角等技术手段对OGMCs表面进行了表征。 结果表明:硅油被成功合成出来,并以共价键方式与MOF膜连接。 OGMC保留了MOF膜表面原有的微纳复合结构以及UiO-66的晶体结构。 OGMC表面的硅油量随硅油生长时间而增加。 但表面冰成核温度和冰粘附力均随硅油生长时间而先下降后升高。 硅油量密切影响微纳复合结构表面的防冰性能。 当硅油生长时间为12~18 h,表面硅/锆物质的量比在8~12时,表面防冰效果最佳,表面冰成核温度可达到-29.6℃,冰粘附力达到8.8 kPa。

Abstract: In this paper, a MOF-based anti-icing coating was prepared by in situ synthesis of the silicone oil lubricating layer on the UiO-66-NH2 coating via click reaction. The amount of silicone oil on surface wastuned by reaction time. The anti-icing performance of the oil-grafted MOF coatings (OGMCs) with different amounts of silicone oil was investigated. The surface morphology and composition were characterized by scanning electron microscopy (SEM), Fourier transform infrared spectrometer (FT-IR), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and contact goniometer. The results show that silicone oil is successfully synthesized and covalently bond to MOF. The OGMCs keep the original micro-nanostructures of MOF coating, as well as the crystal structure of UiO-66. The amount of silicone oil on OGMC increases with reaction time, however, the ice nucleation temperature and ice adhesion decreases first and then increases when the reaction time increases. The anti-icing performance of MOF coating is closely related with the amount of silicone oil. The anti-icing performance of OGMC is optimized when the reaction time is 12~18 h and the molar ratio of Si to Zr is 8~12. The ice nucleation temperature reaches -29.6 ℃ and the ice adhesion reaches 8.8 kPa.
