Summary: The effects of interfacial interaction between nano‐CaCO 3 and PVC on mechanical properties and morphology of PVC/nano‐CaCO 3 composites were studied. Nano‐CaCO 3 was treated with vibromilling in the presence of PVC and coupling agents. The mechanical properties of PVC/treated nano‐CaCO 3 are remarkably improved. Transmission electron microscopy results revealed that vibromilled nano‐CaCO 3 particles are well dispersed in PVC matrix with good homogeneity and well adhered to PVC matrix. Molau test indicated that chemical reaction between newly formed surface of nano‐CaCO 3 and PVC or coupling agent took place. Theoretical calculation results show that the interfacial interaction between PVC and nano‐CaCO 3 are substantially improved through vibromilling treatment of nano‐CaCO 3 in the presence of PVC and coupling agent.Molau test results of the samples in THF.
