As interest continues to grow in Ti3C2Tx and other related MXenes, advancement methods of manipulation their surface functional groups beyond synthesis-based terminations (Tx: -F, -OH, ═O) can provide mechanisms enhance solution processability as well produce improved solid-state device architectures coatings. Here, we report a chemically important modification approach which "solvent-like" polymers, polyethylene glycol carboxylic acid (PEG6-COOH), are covalently attached onto MXenes via esterification chemistry. Surface with PEG6-COOH large ligand loading (up 14% by mass) greatly enhances dispersibility wide range nonpolar organic solvents (e.g., 2.88 mg/mL chloroform) without oxidation two-dimensional flakes or changes the structure ordering. Furthermore, cooperative interactions between polymer chains improve nanoscale assembly uniform microstructures stacked MXene-PEG6 into ordered thin films excellent electrical conductivity (∼16,200 S·cm-1). Most importantly, our covalent ω-functionalized PEG6 ligands (ω-PEG6-COOH, where ω: -NH2, -N3, -CH═CH2) allows for control over degree functionalization (incorporation valency) MXene. We believe that installing valency through short, ion conducting PEG compromising MXenes' features such processability, structural stability, further chemistry tunability performance widens applications.
