Preparation of zinc hydroxystannate-decorated graphene oxide nanohybrids and their synergistic reinforcement on reducing fire hazards of flexible poly (vinyl chloride).

A novel flame retardant, zinc hydroxystannate-decorated graphene oxide (ZHS/GO) nanohybrid, was successfully prepared and well characterized. Herein, the ZHS nanoparticles could not only enhance the flame retardancy of GO with the synergistic flame-retardant effect of ZHS but also prevent the restack of GO to improve the mechanical properties of poly (vinyl chloride) (PVC) matrix. The structure characterization showed ZHS nanoparticles were bonded onto the surface of GO nanosheets and the ZHS nanoparticles were well distributed on the surface of GO.

catena-Poly[[[bis-(thio-cyanato-κN)zinc]bis-[μ-1,3,5-tris-(1H-1,2,4-triazol-1-yl-meth-yl)benzene-κ(2)N(4):N(4')]] mono-hydrate].

In the title complex, {[Zn(NCS)(2)(C(15)H(15)N(9))(2)]·H(2)O}(n), the Zn(II) ion is located on an inversion centre and is six-coordinated in a distorted octa-hedral geometry, coordinated by N atoms from four bridging 1,3,5-tris-(1,2,4-triazol-1-ylmeth-yl)benzene (ttmb) ligands and two terminal SCN(-) counter-anions. Two of the three triazol groups in each ttmb ligand link the Zn(II) atoms, forming a looped-chain structure along [0-11]. The lattice water molecule shows half-occupancy due to disorder around an inversion centre.
