Current methods for the hardening step of functional coatings over different materials imply the use of high temperatures, high energy consumption or long periods of time, which have repercussions on the speed and cost of the product. We report here a simple and low-cost methodology for the functionalization of low-cost stainless steel, which is modular, depending on the functionality pursued: a levelling layer for smoothing the surface of the material, an "easy to clean" property, or both of them. This research is based on sol-gel coatings cured under UV light without requiring high thermal hardening processes, making it applicable to plastics and other sensible materials and possessing high chemical and thermal stability. The film ensures lower processing costs and higher rates of hardening if adequate medium-pressure lamps are employed. This formulation is also well-defined for scaling up the process, so it is possible to perform a continuous coating in large areas by employing mild processing conditions (low temperature, atmospheric pressure). In addition, the sol-gel solution was fully characterized and studied in order to guarantee a long service life before deposition, with a focus on industrial applications in the domestic sector.
目前，在不同材料上制备功能涂层的硬化步骤所采用的方法，意味着要使用高温、高能耗或长时间，这对产品的速度和成本都有影响。我们在此报告一种用于低成本不锈钢功能化的简单且低成本的方法，该方法具有模块化特点，取决于所追求的功能：用于使材料表面光滑的平整层、“易于清洁”的特性，或两者兼具。本研究基于在紫外光下固化的溶胶 - 凝胶涂层，无需高温硬化工艺，使其适用于塑料和其他敏感材料，并具有高化学和热稳定性。如果使用适当的中压灯，该薄膜可确保更低的加工成本和更高的硬化速率。这种配方对于扩大工艺规模也有明确的定义，因此可以通过采用温和的加工条件（低温、大气压）在大面积上进行连续涂层。此外，对溶胶 - 凝胶溶液进行了全面表征和研究，以确保在沉积前有较长的使用寿命，重点关注在家庭领域的工业应用。
