TL;DR: In this article, the effect of interfacial interaction on the tensile properties of polypropylene composites was evaluated by semi-empirical equations developed previously, and the results also proved the validity of the model equations applied.

TL;DR: A study of eight silane coupling agents showed very different effect of these compounds on the mechanical properties of PP/CaCO3 composites, with bulky organofunctional groups form a caged, polycyclic, low-molecular-weight structure on the surface, while silanes with smaller groups tend to condense into open, ladder type, high-molesome-weight polysiloxane chains.

TL;DR: In this article, a detailed study has shown that aminofunctional silanes bond strongly to the surface of the filler, but in the case of multilayer coverage also to the previous layers.

TL;DR: In this article, the tensile properties of polypropylene composites were determined as a function of surface coverage and the chemical composition of the coupling agent, and significant differences were detected in the effect of the silane coupling agents on the composites studied.

TL;DR: The fracture resistance of polypropene/CaCO3 composites was studied as a function of interfacial adhesion in this paper, where the filler was treated with two surfactants and an aminosilane coupling agent.
