Highly Hydrophobic and Superhydrophobic Coatings Based on Linseed Oil and Copolymers of Glycidyl Methacrylate and (Fluoro)Alkyl Methacrylates for Wood Surfaces

The paper discusses the formation of hydrophobic coatings based on linseed oil and copolymers of glycidyl methacrylate and (fluoro)alkyl methacrylates on the surface of pinewood and shows the possibility of achieving a superhydrophobic state with contact angles as large as 154 degrees. Energy-dispersive X-ray analysis has been employed to show that methacrylate copolymers are uniformly distributed over the wood surface and penetrate to a depth of more than 400 mu m. The proposed modification of wood imparts it with stable water-repellent properties, which slow down moisture sorption at the initial stages of a contact with water and reduce water absorption coefficient by a factor of 2.5 after 60-day exposure in water.

Automated summary

This paper discusses the formation of hydrophobic coatings on pinewood surface using linseed oil and copolymers of glycidyl methacrylate and (fluoro)alkyl methacrylates. It shows the potential to achieve a superhydrophobic state with contact angles as large as 154 degrees. The modified wood exhibits stable water-repellent properties, reducing moisture sorption and water absorption coefficient.
