In this research work, the effect of the change in the surface area of silicon dioxide nanoparticles of the same size on mech. properties of poly(lactic acid) nanocomposites (PLA) was studied, as well as the role of coupling agent amount in the compatibility of these nanomaterials. We consider a spherical silicon dioxide with a surface area of 170-200 m2/g (labeled as S-SiO2) and another considered amorphous with a surface area of 180-600 m2/g (labeled as P-SiO2). According to obtained results, for nanomaterials with high surface area, it was observed while increasing coupling agent amount, the elasticity of the composite was observed to increase. In contrast, in nanomaterials with spherical nanoparticles, it was observed that as the amount of coupling agent decreases, the resistance of the material increases, reaching a maximum when a 10:2 ratio is used. Furthermore, it is observed that the incorporation of nanoparticles with high surface areas area does not modify the crystallization rate significantly. Besides, in both cases, it was observed that the highest crystallization rate is reached when a 10:2 ratio is used. Finally, a maximum in the 10:2 ratio was observed for the compatibility in both particles, which was manifested in an increase in the storage module through a dynamic mech. anal. The rate of crystal formation as well as the number of formed crystals have a considerable effect on mech. properties of nanocomposites when the surface area is modified.
