聚合物泡沫是多孔、轻质和低成本的材料。传统上，聚合物泡沫已用于家用电器、汽车、建筑、运输和航空航天。然而，现代进步和材料需求促进了这些泡沫的应用领域扩展到其他技术领域，包括储能装置和锂离子电池、压阻传感器、生物医学支架、油水分离和水修复等，通过涂层。这些低成本泡沫的可持续技术解决方案现已通过它们的特性（高表面积、开孔、低密度和柔韧性）的相互属性、众多先进材料（例如碳纳米管、石墨烯和金属氧化物纳米粒子），以及多功能和创新的涂层方法。在这篇综述中，我们讨论了各种聚合物泡沫表面处理技术及其应用的最新进展。广泛使用和研究最多的热固性泡沫，即软质聚氨酯、三聚氰胺甲醛泡沫、聚丙烯和乙烯醋酸乙烯酯等热塑性泡沫和聚苯乙烯泡沫的表面改性被认为特别强调开孔泡沫。此外，对环境净化和油吸附有很大影响的疏水涂层也被强调。研究了使用广泛的纳米粒子、聚合物和有机化合物作为涂层材料。疏水性、吸附能力、导电性和导热性、阻燃性等固有特性如何明确讨论了通过改性影响泡沫的电磁干扰屏蔽和生物相容性。还讨论了使用改性泡沫作为锂离子电池催化和电极载体的方法。已发现这些涂层基材的性能取决于涂层材料、涂层方法的功效和表面性能。最后，展望了这些泡沫在大规模使用中的实际挑战以及在环境清洁和能源储存方面的未来前景。已发现这些涂层基材的性能取决于涂层材料、涂层方法的功效和表面性能。最后，展望了这些泡沫在大规模使用中的实际挑战以及在环境清洁和能源储存方面的未来前景。已发现这些涂层基材的性能取决于涂层材料、涂层方法的功效和表面性能。最后，展望了这些泡沫在大规模使用中的实际挑战以及在环境清洁和能源储存方面的未来前景。

Exploring the Multifunctional Applications of Surface-Coated Polymeric Foams─A Review

Polymeric foams are porous, lightweight, and low-cost materials. Traditionally, polymeric foams have been used in home appliances, automotive, construction, transportation, and aerospace. However, the modern advancements and the materials demand have fostered the expansion of the application realm of these foams to other technological areas encompassing energy storage devices and Li-ion batteries, piezoresistive sensors, biomedical scaffolds, oil–water separation and water remediation etc., through coating. The sustainable technological solutions of these low-cost foams have now been realized through mutual attributes of their properties (high surface area, open-cell, low density, and flexibility), the availability of numerous advanced materials (e.g., carbon nanotubes, graphenes and metal oxide nanoparticles), and versatile and innovative coating methods. In this review, we discuss the recent progress in coating techniques of various polymeric foams by surface treatments and their applications. The surface modification of widely used and the most studied thermoset foams, namely, flexible polyurethane, melamine formaldehyde foams, thermoplastic foams such as polypropylene and ethylene vinylene acetate, and polystyrene foams are considered with special emphasis on open-cell foams. Further, hydrophobic coatings which have a large implication in environment cleanup and oil adsorption are highlighted. The use of a wide spectrum of nanoparticles, polymers, and organic compounds as coating materials is investigated. How the inherent properties such as hydrophobicity, adsorption capability, electrical and thermal conductivities, fire retardancy, electromagnetic interference shielding, and biocompatibility of the foam are influenced through modification is explicitly discussed. The methods which have used the modified foam as a support for catalysis and electrodes in Li-ion batteries are also deliberated. The properties of these coated substrates have been found to rely on the coating material, efficacy of the coating method, and the surface properties. Lastly, practical challenges of these foams in large scale use and future prospects in environment cleanup and energy storage have been envisioned.
