Effect of calcium carbonate nanoparticles on the crystallization kinetics PA66
Polyamide 66 (PA66) in engineering plastics is used. However, its poor strength has limited applications. Thus, the strength of the PA66 is highly associated with the way it has been modified. Generally, the strength of a plastic and elastomer matrix is reduced stiffness and heat resistance.
Finding a convenient way for the strength of PA66 without reducing the stiffness and heat resistance of polymers is a crucial target for researchers in this field. calcium carbonate nanoparticles affect the crystallization kinetics PA66.
In this study, calcium carbonate nanoparticles have been used for the strength of PA66 through the molten mixture. Isothermal crystallization kinetics of nanoparticle effect on Differential scanning calorimetry technique was studied for Polyamide 66. The results showed that by adding a small number of nanoparticles, the PA66 crystallization rate can be increased, crystallization temperature increases, and crystal size distribution during crystal growth is limited. Changes in nuclear energy are based on the resulting crystal Avrami equation of Hoffman’s theory. With the development of the spherulite radial surface, the free energy of the crystals decreases with increasing amounts of nanoparticles. The results showed that crystal structure and crystallization kinetics Composite PA66 / Nano carbonate calcium, used nanoparticles, was not a nucleation agent for PA66.
