| Popis: | The isothermal and nonisothermal crystallization behaviors of PVDF/MWCNT composites containing pristine and hydroxide groups (-OH) functionalized MWCNT (MWCNT-g-OH) were investigated using Avrami, Ozawa, and Mo equations. It was found that Avrami and Mo equations were suitable for describing the crystallization kinetics while the Ozawa equation failed. The crystallization kinetics was greatly influenced by the MWCNT loading and the interfacial interactions between MWCNT and PVDF matrix. MWCNT-g-OH was more effective in increasing the crystallization rate due to the stronger interfacial interactions. Strong interfacial interactions ensure good contact between the PVDF and MWCNT-g-OH, which was beneficial for the heterogeneous nucleating process. |
