Polyethersulfone (PES) repeating unit. Polyethersulfone (PES) PES is a thermoplastic, further classified as a sulfone plastic. Passivation is achieved by the use of a passivation mixture comprising a main monomer, a passivating monomer that is different from the main monomer, and a crosslinking agent, which mixture upon polymerization results in the substantial elimination of the undesirable non-specific interaction between biomolecules and the protective polymeric . It has a moderately high ductility and a moderately high tensile strength among thermoplastics. et al. Polyethersulfone (PES) has an outstanding ability to withstand exposure to elevated temperatures in air and water for prolonged periods. Even though PES is a high-temperature engineering thermoplastic, it can be processed on conventional plastics processing equipment. Hydrophobicity of polyethersulfone is considered one main disadvantage of using this material because hydrophobic surface Some known techniques like UV- assisted graft polymerization using certain monomers were reviewed and conclusions based on the techniques and their results were made. Polyethersulfone Characteristics. Although the polymers prepared from these different routes had the same nominal repeat unit, two-monomer route was preferred .
