Title : Flexible fabric-based nanostructured color-generating film systems
Abstract:
Flexible fabric-based nanostructured color-generating film system consists of three layers: the inner layer is a metal-based infrared shielding material with natural antibacterial properties sprayed onto one side of a polymeric flexible fabric; the middle layer is a metal-based electromagnetic shielding material sprayed onto the other side of the polymeric flexible fabric; and the outer layer is a ceramic-based waterproof and anti-fouling film layer. Unlike traditional methods that apply coatings using techniques such as coating application, this technology employs vacuum deposition to generate high-purity nano-film layers on the substrate. The advantages of using the vacuum deposition method are as follows: Firstly, the particle bombardment effect during vacuum deposition can enhance the adhesion between the functional layers and the substrate, thereby increasing the service life of the finished product. Secondly, the proportion of functional materials in the functional layers formed by vacuum deposition can approach 100%, mitigating the drawbacks of reduced functionality and increased coating thickness caused by the need to add large amounts of binders in conventional coating materials. This method enables the surface treatment of flexible substrates with nano-film layers under conditions of water-free operation, energy conservation, pollution-free processing, and zero emissions. In particular, it improves the bonding strength between the flexible substrate and the surface nano-film layers, allowing the treated flexible substrates to be directly applied in various applications. Research is being conducted on the surface treatment of flexible substrates with nano-film layers, particularly focusing on the design of these nano-film layers to achieve the addition of multiple functionalities onto the surface of flexible substrates. This includes the superposition of various functions such as UV resistance, infrared resistance, and electromagnetic shielding.
