The effect of nanocaly on crystalline structure of poly(vinylidene fuoride). PVDF. and the morphology of the resulting nano-composite were investigated using different characterization techniques. The presence of 3wt% Cloisite 30B in PVDF matrix results in 11 fold increase in the percentage of beta crystalline content of the polymer. https://www.roneverhart.com/Whirlwind-Direct-2-Direct-Box-p14308/
