“…Halloysite is a natural aluminosilicate, chemically similar to Kaolin, from natural deposits in countries such as China, Brazil, and France, among others (Du, Guo, & Jia, 2006). Depending on its origin, halloysite can be found in the form of spheres, plates, elongated prisms, or nanotubes, being the last ones the most used as reinforcements in polymers (Peres & Oréfice, 2020). HNT are hollow tubular structures consisting of multiple layers with dimensions ranging from 500 to 1000 nm in length, 15 to 100 nm in inner diameter and 40 to 120 nm in outer diameter (Pal, Kundu, Malas, & Das, 2014;Schmitt, Prashantha, Soulestin, Lacrampe, & Krawczak, 2012) One of the most important characteristics of HNTs is the difference in chemical structure between the inner and outer surface, on the one hand, the outer surface is composed of siloxane while the inner layers are composed of aluminol groups (Carli, Daitx, Soares, Crespo, & Mauler, 2014).…”
