Modification of Ti3C2Tx MXene with hyperbranched polyethylene ionomers: stable dispersions in nonpolar/low-polarity organic solvents, oxidation protection, and potential application in supercapacitors

Hydrophilic MXene nanosheets are intercalated with hydrophobic hyperbranched polyethylene ionomers containing quaternary ammonium ions to render ionomer-modified multi- or few-layer MXene sheets with marked changed physiochemical properties.
