520 |a An ab initio derived transferable polarizable force-field has been developed for Zinc sulphide (ZnS) nanoparticle (NP) and ZnS NP-PMMA nanocomposite. The structure and elastic constants of bulk ZnS using the new force-field are within a few percent of experimental observables. The new force-field show remarkable ability to reproduce structures and nucleation energies of nanoclusters (Zn1S1-Zn12S12) as validated with that of the density functional theory calculations. A qualitative agreement of the radial distribution functions of Zn-O, in a ZnS nanocluster-PMMA system, obtained using molecular mechanics molecular dynamics (MD) and ab initio MD (AIMD) simulations indicates that the ZnS-PMMA interaction through Zn-O bonding is explained satisfactorily by our force-field
