Abstract

A method is proposed for increasing the resistance of a superhydrophobic coating based on a CNT xerogel to frost deposition through the use of decorating nanoparticles. The effects of the addition of fullerenes, carbon nanoonions (CNOs), detonation nanodiamonds, silicon dioxide, and paraffin to the xerogel are tested. An increase in the resistance of the coating to the deposition of condensate in the form of frost is revealed. The addition of fullerene C₆₀ leads to the best results. Increasing the resistance to icing allows us to spend less power on heating the surface during short cold snaps, bypassing the anti-icing properties of the protective superhydrophobic layer. However, the application of this approach shows a deterioration in the resistance of the coating to the penetration of the spray. This is given a qualitative explanation and measures to combat it are proposed. No effect of the additives on the mechanical properties of the coating or its resistance to damage is detected. In additon, decorating additives affect the formation of the coating relief. With this, it is possible to influence the stochastic processes of the formation of roughness during the drying of the xerogel.

基于修饰碳纳米颗粒的超疏水涂层

摘要

提出了一种通过使用装饰纳米粒子来提高基于碳纳米管干凝胶的超疏水涂层对霜沉积的抵抗力的方法。测试了在干凝胶中添加富勒烯、碳纳米离子 (CNO)、爆炸纳米金刚石、二氧化硅和石蜡的效果。结果表明，涂​​层对霜形式的冷凝水沉积的抵抗力有所增加。添加富勒烯 C ₆₀可获得最佳效果。提高抗结冰能力使我们能够在短暂的寒潮期间花费更少的能量来加热表面，从而绕过保护性超疏水层的防结冰特性。然而，这种方法的应用表明涂层对喷雾渗透的抵抗力下降。对此进行了定性解释并提出了应对措施。未检测到添加剂对涂层机械性能或其抗损坏性的影响。此外，装饰添加剂影响涂层浮雕的形成。由此，可以影响干凝胶干燥过程中粗糙度形成的随机过程。
