Interpretive Summary:

Technical Abstract: Alkyl cyanoacrylates have long been used for the synthesis of colloidal nanoparticles. In the involved polymerization reaction, OH- ions derived from dissociation of water have been used as an initiator. In the current research, functional groups on the surface of proteins were utilized as an initiator for the polymerization. Following this reaction scheme, a hydrophilic polymer (protein) was covalently bound to the backbone of poly(alkyl cyanoacrylate), which is hydrophobic. The resultant block copolymer was amphiphilic in nature, and formed nanoparticles in the reaction medium. The solution containing these nanoparticles showed an excellent coating capability on the surface of hydrophobic materials. A simple spray coating changed the wetting property of the material instantly and dramatically. Depending on the choice of protein, performance of the final product showed variation.
