Abstract

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.
