A study on self-healing properties of fluorine-based functional polymer with excellent scratch recovery

In this article, Acrylate-based self-healing polymers were synthesized that can be recovered and have low friction coefficients and chemical resistance and experience low water/oil/dirt accumulation due to the presence of a fluorinated layer. The basic approach to self-healing materials is to introduce perfluoroalkyl dangling chains at the end of the star block co-polymer (PCL) to impart hydrophobic properties to the material as well as to repair wounds in response to heat. In addition, building blocks were prepared with acrylate (2-hydroxtyethyl methacrylate) and synthesized in order to obtain a material that is resistant to scratches and can undergo self-healing while maintaining thee hydrophobic properties. We analyzed the material using nano-indentation and contact angle measurements to confirm the properties of the final synthesized self-healing material.
