| Résumé : |
Resins have been widely used in a variety of industry fields for more than a century, such as coatings, adhesives, or automotive. Their low cost and workability are extremely useful in creating more and more advanced materials due to their chemical structure (Ghaffari et al. in Surf Interfaces 17:100340, 2019). Common problem today is the wetting tendency of various materials which in the end can result in further damage in the structure because of atmospheric conditions. Nowadays, scientists are trying to find better ways to improve the properties of coatings or composites in cases like hydrophobicity or icephobicity. One of the examp les are fluorinated organic compounds with good linking properties to the substrate (Qin et al. in Mater Today Commun 22:100770, 2020). Because o f that, to im prove the properties of a basic epoxy resin, its chain has been modified with hydrophobic compounds with different chain lengths. Influence of modifiers’ molecule size on hydrophobic and ice adhesion properties of obtained epoxy resins has been tested. Chemical composition of prepared coatings was analyzed by FTIR. Moreover, their thermal stability was investigated using TG and DSC measurements. Additionally, wettability of the samples was analyzed with a goniometer. Furthermore, their ice adhesion tests were performed on a dedicated apparatus. As a result, presented work provides a critique overview and concept of promising icephobic and hydrophobic coatings in the industry. Moreover, these products have a high chance to be developed further. |
