2D nanosheet-constructed hybrid nanofillers for polymer nanocomposites with synergistic dispersion and function

Abstract

Polymer nanocomposites (PNCs) are new-emerging multicomponent polymer composites consisting of a polymer matrix and well dispersed nanofillers. Nanofillers can be divided into one-dimensional, two-dimensional (2D), or three-dimensional nanoparticles according to their dimensions. Due to their outstanding physical properties, the achievement of homogeneous dispersion of 2D nanofillers in the polymer matrix plays a decisive role in the fabrication of high-performance and multifunctional PNCs. The construction of 2D nanosheets into hybrid nanofillers provides a new idea for achieving homogeneous dispersion of 2D nanofillers in the polymer matrix. In this review, recent developments on the design strategies and controllable preparation methods of hybrid nanofillers containing 2D nanosheets are summarized. The preparation, structure, and physical properties of PNCs with 2D nanosheet-constructed hybrid nanofillers are discussed in detail. Finally, challenges and future prospects of PNCs with 2D nanosheet-constructed hybrid nanofillers are highlighted.
