Poly oxidation
WebMay 7, 2024 · Polydopamine (PDA) is a polymer easily obtained by oxidation of dopamine. It is composed of indole and dopamine units in various oxidation states and to a lesser extent of pyrroles. It adheres to all type of surfaces even under water due to its abundant catechol moieties assisted by amino groups. WebNonpolar polymer coatings based on polyisobutyl\ ene and tri-block copolymer of isobutylene with styrene showed ability to protect MXene films from oxidation during a long-term period. After 400 days of storage, the resistivity of the MXene films coated with PIB and SIBS increased by 1.8 and 1.4 times, \ respectively.
