摘要: Calcium carbonate was synthesized by in situ deposition technique and its nano size (35–60 nm) confirmed transmission electron microscopy (TEM). Composites of the filler CaCO3 (micro nano) matrix poly(vinyl chloride) (PVC) were prepared with different loadings (0–5 wt%) melt intercalation. Brabender torque rheometer equipped an internal mixer has been used for preparation formulations composites. The effect content both nano- micro level on nanostructure properties is reported here. nanostructures studied wide angle X-ray diffraction scanning microscopy. mechanical, thermal, dynamic mechanical PVC/micro- nano-CaCO3 composites characterized using universal testing machine, thermogravimetric analyzer, analyzer. results thermal analysis indicated that stability PVC/nano-CaCO3 improved as compared corresponding microcomposites, pristine PVC maximum improvement obtained at 1 3 phr loadings. However, tensile strength decreased significantly increase loading micro-CaCO3, whereas storage modulus glass transition temperature increased significantly.
