Precision Grafting-From of Diblock Copolymer Brushes on MXene Nanosheets.

ABSTRACT: 2D MXene materials offer outstanding optical, electrical, and mechanical properties, which can be used to produce multifunctional high-performance polymer-matrix composites. Here, we demonstrate the fabrication of robust covalently bonded polymer shells via the implementation of surface-initiated atom transfer radical polymerization (SI-ATRP) on heterogeneous 2D nanosheets. This robust grafting-from methodology was demonstrated through selective esterification of hydroxyl groups on Ti₃C₂T _x MXene with 2-bromoisobutyryl bromide. This approach enables the synthesis of diblock polymer brushes with sequential hydrophobic and hydrophilic blocks with predetermined, narrowly dispersed molecular weight and a low polydispersity index firmly bonded to
