Nanocomposite coatings, i.e., a combination of nanocompounds, and a polymer matrix together with suitable additives and solvents is a very versatile method for producing multifunctional coatings. Some of the most desired coating properties have a high repellency to liquids (e.g., superhydrophobic and/or superoleophobic) and electrical and thermal conductivities. From a practical perspective, coatings that can be sprayed are very suitable for large-scale production, conformity, and reduced time and cost. Carbon-based, metallic, and ceramic are the three groups of nanocompounds commonly used to formulate spray-on nanocomposite coatings. In this invited feature article, we discuss the applications, advantages, and challenges of using such nanocompounds to produce coatings with good water repellency or/and elevated electrical or/and thermal conductivities. We also discuss the role of additives and solvents briefly in relation to the properties of the coatings. Important spraying parameters, such as stand-off distance and its influence on the final coating properties, will also be examined. Our overall aim is to provide a guideline for the production of practical multifunctional nanocomposites utilizing carbon-based, metallic, or ceramic nanoparticles or nanofibers that covers both aspects of in-air wettability and conductivity under one umbrella.

喷涂纳米复合涂料：润湿性和导电性。

纳米复合涂料，即纳米化合物和聚合物基质与合适的添加剂和溶剂的组合，是生产多功能涂料的一种非常通用的方法。一些最理想的涂层性能对液体（例如，超疏水和/或超疏油）具有很高的排斥性，并具有导电性和导热性。从实用的角度来看，可以喷涂的涂料非常适合大规模生产，贴合性以及减少的时间和成本。碳基，金属和陶瓷是三类纳米化合物，通常用于配制喷涂纳米复合涂料。在这篇受邀的专题文章中，我们将讨论应用程序，优势，以及使用这种纳米化合物生产具有良好拒水性或/和提高的电导率//和导热率的涂层的挑战。我们还将简要讨论添加剂和溶剂在涂料性能方面的作用。还应检查重要的喷涂参数，例如间隔距离及其对最终涂层性能的影响。我们的总体目标是为使用碳基，金属或陶瓷纳米颗粒或纳米纤维的实用多功能纳米复合材料的生产提供指导，该复合材料涵盖了在一个伞下的空气可湿性和电导率这两个方面。例如支脚距离及其对最终涂层性能的影响，也将进行检查。我们的总体目标是为使用碳基，金属或陶瓷纳米颗粒或纳米纤维的实用多功能纳米复合材料的生产提供指导，该复合材料涵盖了在一个伞下的空气可湿性和电导率这两个方面。例如支脚距离及其对最终涂层性能的影响，也将进行检查。我们的总体目标是为使用碳基，金属或陶瓷纳米颗粒或纳米纤维的实用多功能纳米复合材料的生产提供指导，该复合材料涵盖了在一个伞下的空气可湿性和电导率这两个方面。
