Self-healing materials are under intense development since the self-healing ability can improve the safety,lifetime,energy efficiency and environmental protection of manmade *** sharp contrast,most synthetic materials fail after damage or *** kinds of traditional polymer nanocomposites(PNCs)would not only waste the fossil fuel,but also cause"white pollution".With the great demand of the sustainable development faced by the whole world,for decades,scientific researchers have dreamed of endowing the self-healing capability with polymer nanocomposites(PNCs).Obviously,most self-healing materials requires the input of external energy in the form of heat or *** is evident that the self-healing extent could be accelerated by increasing the healing temperature or ***,little attention has been put on the relation between the healing temperature and the healing *** the advantage of molecular dynamics simulation,we design a polymer brush system,where the polymer chains are grafted on the surface of nanoparticles(NPs).This matrix-free polymer nanocomposites are further constructed via the strong interaction between the end-groups of the grafted polymer *** this work,we firstly study the effect of the grafting density on the dispersion state of NPs,as well as the glass transition temperature ***,we mainly study the tensile failure behavior and the self-healing kinetics under different healing temperatures and different healing times,aiming to establish an equivalent effect between the temperature and the time.
