Hydrophilic surface modification of polytetrafluoroethylene by ultraviolet induced grafting polymerization

Key Points

• Enhanced hydrophilicity improves the interaction of polytetrafluoroethylene with water and other polar solvents, making it suitable for various applications.
• The degree of surface modification was quantified as an increase in water contact angle of over 30 degrees, indicating significant change.
• Grafting polymerization was employed to modify the surface of polytetrafluoroethylene with hydrophilic segments, enhancing its surface characteristics.
• The findings may enable better adhesion and compatibility in biomedical and engineering fields, boosting the material's utility.
