abstract

• Poly(ethylene terephthalate) (PET) has been mixed with fluorite (CaF2) particles to obtain micro- and nano-composites aiming to obtain a hybrid multifilament. In first term, the use of two montanic waxes and an amide wax as dispersing agents towards the compatibilization of the inorganic and organic components of the CaF2/PET composite were considered. To do this, non-isothermal crystallization studies by differential scanning calorimetry have been carried out. Moreover, the influence of the CaF2 particle size and concentration on the thermal properties of the system have been also studied by this technique. Finally, the extrapolation of the results has materialised as a novel PET/CaF2 hybrid multifilament. Thermal and mechanical properties and molecular weight of the multifilament have been as well evaluated. © 2020 Elsevier Ltd
