Abstract :
The crystallization kinetics of isotactic polypropylene (iPP/LLDPE) blends, and iPP composite containing nano kaolin particles has been investigated. The addition of nano kaolin and LLDPE to iPP affects both its nucleation and spherulitic growth rate. With the addition of the nano filler particles, significant increase in the nucleation and maximum growth rate were observed. To improve the dispersion in the matrix, the filler particles were treated with silane. An experimentally determined value for the Avrami exponent was calculated. The Scanning electron microscopy indicates that the nano particles cause a finer dispersion of the LLDPE component in the iPP matrix. Due to the presence of nano size filler, additional heterogeneous nucleation of the iPP nuclei occurs through the enhancement of the interface area.
