Effect of nucleating agent on a polyethylene blend
Morphology of polymers has been widely studied in order to enhance their structural properties. In the case of polyolefin, additives are often used to modify the morphology and improve the macroscopic physical properties. In the last decade, the use of nucleating agents has attracted many interests for improved optical and mechanical properties. Dibenzylidene sorbitol (DBS), a physical molecular organogelator, has shown nucleation efficiency on different polymers, like polyethylene (PE). This study investigates the effect of different amount of DBS on the nucleation and crystallisation of PE. A potential application as dielectric is given by the improved space charge distribution in samples containing DBS.
