Abstract

Abstract: A simple and efficient polymer grafting onto hydrothermal carbonization (HTC)‐derived materials is described. The method pertains to the Diels–Alder cycloaddition reaction of furan moieties present on the surface of a HTC material with the maleimide groups stemming from a maleimide protected poly(ethylene glycol) (Me‐PEG‐MI) by a retro Diels‐Alder reaction. The precursor polymer, HTC material, and final product are characterized. Successful grafting is confirmed by elemental analysis, X‐ray photoelectron spectroscopy, Fourier transform infrared spectroscopy, and dispersion studies. Abstract : Facile "graft‐to" cycloaddition‐mediated polymer functionalization of hydrothermal carbonization (HTC)‐derived materials is carried out by use of a dienophile‐functionalized polymer. Masked maleimide terminated poly(ethylene glycol) (PEG) is used as a model dienophile containing polymer to graft onto the surface of the HTC material. Analysis of PEGylated carbons (Fourier transform infrared, elemental analysis, X‐ray photoelectron spectroscopy, and dispersion studies) all indicate the successful surface modification.
