Luminescent coatings have several exciting applications. Polymers have been reported as both corrosion inhibitors and luminescent materials. Mild steel corrosion is a major economic problem. Moreover, full-color luminescence from one material is a hot research topic due to the advantages of such materials. Here, some liquid crystal polymers (LCPs) have been checked as corrosion inhibitors of mild steel in an acidic medium (1.0 M H₂SO₄) through potentiodynamic polarization techniques. The LCPs showed high anticorrosion efficiency depending on their structure. These LCPs were confirmed as mixed-type inhibitors. Furthermore, the studied LCPs have aggregation-induced emission behavior with controlled emission colors (blue, white, and green) via adjusting the solution concentration. The molecular aggregation changed according to the solution concentration, and thus the relative emission intensity was tuned at different wavelengths of the visible range. Interestingly, moderate solution concentrations displayed white emission from a single component. The LCPs also exhibited a stable emission behavior at high temperatures. Because these materials combine the advantages of polymers, LCs, corrosion inhibitors, and white-light emitters, these current findings should open a door to develop more attractive luminescent coatings.

发光涂层有几个令人兴奋的应用。聚合物已被报道为腐蚀抑制剂和发光材料。低碳钢腐蚀是一个主要的经济问题。此外，由于这种材料的优点，一种材料的全色发光是一个热门的研究课题。在这里，一些液晶聚合物 (LCP) 已被检查作为酸性介质 (1.0 M H ₂ SO ₄) 通过动电位极化技术。LCPs 表现出高的防腐效率，这取决于它们的结构。这些 LCP 被确认为混合型抑制剂。此外，所研究的 LCP 具有聚集诱导的发射行为，通过调节溶液浓度控制发射颜色（蓝色、白色和绿色）。分子聚集根据溶液浓度而变化，因此在可见光范围的不同波长下调整相对发射强度。有趣的是，中等浓度的溶液显示来自单一组分的白色发射。LCP 在高温下也表现出稳定的发射行为。因为这些材料结合了聚合物、液晶、腐蚀抑制剂和白光发射器的优点，
