Abstract The present invention relates to the process of obtaining a novel polypropylene nanocomposite with carbon nanotubes and titanium dioxide by melt extrusion. Said process consists of using the nanofillers in an NC/TiO2 ratio of 1:1 and 2:1 in the formulation ranging from 1% to 10% by weight, a load of 10% by weight, an increase of 18.3% with respect to the PP, a decrease in the HRR peak, and a residual carbon content of 91.1% after ignition when the nanocomposite presents a nanoparticle load of 10% by weight. La presente invención se refiere al proceso de obtención de un nanocompuesto novedoso de polipropileno con nanotubos de carbono y dióxido de titanio por extrusión en fundido. Las nanocargas se utilizaron en una relación NC/TiO2 1:1 y 2:1; en la formulación va de 1 a 10 % en peso con respecto al peso total del nanocompuesto. El módulo de Young en el nanocompuesto con una carga del 10 % en peso presentó un incremento del 18.3% con respecto al PP sin cargas. Además, se observa una disminución en el pico HRR comparado con el PP sin carga de nanopartículas y un contenido de carbono residual del 91.1 % después de la ignición cuando el nanocompuesto presenta una carga de nanopartículas del 10 % en peso.
