“…Besides, TiO 2 has the added value of being the primary inorganic pigment used in the coloration of plastics. On the other hand, this oxide is insoluble in most acids, which makes processing difficult since it requires large amounts of energy to achieve optimal dispersion in polymer matrices, due to the formation of agglomerates due to the highly attractive forces among particles (Mendoza, Peña-Juárez, Perez, & Gonzalez-Calderon, 2020). Surface modification is the most common strategy to minimize this attraction and to improve colloidal stability (Delgado Alvarado, Peña Juárez, Perez Perez, Perez, & Gonzalez, 2019).…”
