On the nano-toughening of polymers and fibre composites

摘要

In recent years,the availability of a wide range of nano-sized modifiers andparticles and their increasing ease of being incorporated into polymer matrices hasseen an evolution of conventional composite materials to a new class of polymernanocomposites.Many engineering applications of polymer nanocomposites (e.g.,thermal interface materials,LED devices,etc) require them to possess not onlysuperior mechanical (e.g.,toughness,stiffness,strength,etc) but also improvedphysical properties (e.g.,thermal conductivity,permeability,optical transparency,fireretardancy,etc).Herein,these two aspects will be discussed.
