Effect of the Composition of Copolymers Based on Glycidyl Methacrylate and Fluoroalkyl Methacrylates on the Free Energy and Lyophilic Properties of the Modified Surface

Abstract

This study proposes to use reactive copolymers based on glycidyl methacrylate and fluoroalkyl methacrylates with a low fluorine content in the monomer unit as agents to reduce the surface free energy (SFE). This work reveals the effect of the structure and composition of copolymers on the SFE and water-repellent properties of these coatings. On a smooth surface, coatings based on copolymers of glycidyl methacrylate and fluoroalkyl methacrylates with fluorine atoms in the monomer unit ranging from three to seven are characterized by SFE values in the range from 25 to 13 mN/m, which is comparable to the values for polyhedral oligomeric silsesquioxanes and perfluoroalkyl acrylates. On textured aluminum surfaces, the obtained coatings provide time-stable superhydrophobic properties with contact angles up to 170° and sliding angles up to 2°. The possibility of using copolymers based on glycidyl methacrylate and fluoroalkyl methacrylates for the creation of self-cleaning polymer coatings is shown.

Toward Water and Oil Repellent Coating: Synthesis of Fluorinated Methacrylate-Glycidyl Methacrylate Copolymers

“…Klimov et al also developed self-cleaning coatings based on diblock copolymers of PGMA and PFMA with fluorine atoms in the monomer unit ranging from three to seven. They also found that by increasing the fluorine content in the copolymers, water repellency was enhanced …”

“…They also found that by increasing the fluorine content in the copolymers, water repellency was enhanced. 52 To this end, P(GMA-co-FMA) copolymers have the capability to serve as water and oil repellent materials. To our knowledge, only a few articles have reported on grafting P(GMA-co-FMA) random copolymers onto surfaces to create hydrophobic/oleophobic nanocoatings.…”

“…GMA-based copolymers are of great importance in biotechnological applications since the epoxy group can be easily converted to other functional groups. In addition, homogeneous and heterogeneous polymer networks can be prepared with GMA used in coatings, matrix resins and adhesives (Wang et al, 2022;Liu et al, 2022;Waly et al, 2020;Klimow et al, 2022;Wang & Hutchinson, 2008;Muzammil et al, 2017;May, 1988;Matt et al,2021;Kovar et al, 1982;Yılmaz & Coşkun, 1982). Polyethylene glycol (PEG) is a straight or branched chain polymer in which oxygen and ethylene units are sequentially bonded to each other.…”
