In this work, a new nano‐reinforced polypropylene filament was produced and fabricated by 3D printing to create a nanocomposite with a good balance between stiffness and impact resistance properties. Nanocomposite filament with 0.5, 1.0, and 1.5 wt% of functionalized halloysite nanotubes was prepared. The chemical modification was carried out to obtain a reinforcement that could act as an improved β‐nucleating agent and characterized by infrared spectroscopy. The spectrum showed the appearance of two new bands at 1571 and 1410 cm−1, which could indicate an interaction between the pimelic acid molecules and the oxygenated surface of the halloysite nanotubes. Energy dispersive X‐ray spectroscopy analysis confirmed a good dispersion of the modified reinforcement along the surface of the nanocomposite filament. Wide‐angle X‐ray scattering and differential scanning calorimetry analyses showed the improvement of the β‐nucleating ability of the halloysite nanotubes through new chemically functionalized, obtaining percentages of β‐crystal of 80% for the nanocomposite reinforced with 0.5 wt%. The dynamic mechanical analysis showed that the 3D‐printed functionalized nanocomposites presented higher storage and loss modulus (an increase of 148% and 122%, respectively). Finally, the impact strength properties increased by 90%, 108%, and 21% for the functionalized nanocomposites with 0.5, 1.0, and 1.5 wt%, respectively.Highlights Chemical functionalization of a natural reinforcement as a ‐nucleating agent. 3D printing polypropylene nanocomposites with enhanced properties.

“…O aumento no teor da fase termoplástica resulta em elevado módulo elástico, e quando o maior teor é a borracha vulcanizada observa-se melhora na elongação na ruptura do TPV. Estes materiais são utilizados nas indústrias automobilísticas em substituição a borracha convencional, reduzindo o impacto ambiental (Bouchart et al, 2008;Innes et al 2023;Ponsard-Fillette et al, 2005;Song et al 2023).…”

“…Desde então, muitos estudos se concentraram no uso de pares de borracha e plástico compatíveis para preparar TPVs com domínios de borracha finos e boas propriedades (Yao et al, 2016ª, 2016b. Os TPVs produzidos pelos polimeros EPDM (terpolimero de Etileno-Propileno-Dieno) e PP (polipropileno) têm compatibilidade tecnológica, polímeros apolares (Innes et al, 2023;Song et al, 2023).…”

“…Essa abordagem não apenas reduz os custos, mas também melhora a resistência dos materiais em comparação com os termoplásticos tradicionais. Os TPVs, atualmente, são utilizados para substituir as borrachas vulcanizadas em diversas aplicações na indústria automobilística, pois combinam a elasticidade dos elastômeros com a reciclabilidade dos termoplásticos (Innes et al, 2023;Ning et al, 2018;Tian et al, 2012;Yao et al, 2016).…”

Este estudo aborda a utilização sustentável de resíduos sólidos, com adição de pó de pneu no Polietileno para produzir TermoPlásticos Vulcanizados (TPVs). A técnica de compatibilização não reativa mostrou melhorias no módulo elástico do PEBD. As amostras compatibilizadas com EVA apresentaram menor variação no envelhecimento, e maior resistência ao impacto quando combinadas com SBR. Os resultados mostram a influência da massa molar no escoamento dos polímeros. O estudo contribui para o desenvolvimento de TPVs sustentáveis e melhoria nas propriedades físico-mecânicas. A iniciação científica em TPV proporcionou aos alunos habilidades investigativas e científicas, preparando-os para enfrentar desafios no mercado de trabalho.
