Multicomponent-Reaction-Ready Biomass-Sourced Organic Hybrids Fabricated via the Surface Immobilization of Polymers with Lignin-Based Compounds

Compounds derived from two major biomass components, cellulose and lignin, were artificially re-combined via the radiation-induced graft polymerization of vinyl monomers, which could be potentially sourced from lignin, onto cellulose fabric. This process yielded organic hybrids featuring a cellulose substrate and surface aldehyde groups from lignin-obtained vanillin. Then, the surface Kabachnik-Fields three-component reaction (KF-3CR) of poly(methacrylated vanillin) (PMV) sourced aldehydes was carried out with amines and phosphites. Overall, the surface KF-3CR on the cellulose fabric grafted with PMV represents a facile preparation of multi-functional molecules on cellulose surfaces along with α-amino phosphonate ester integrations.
