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.

获得 PET-CaF2 混合复丝：非等温结晶研究

摘要 聚对苯二甲酸乙二醇酯 (PET) 与萤石 (CaF2) 颗粒混合以获得微米和纳米复合材料，旨在获得混合复丝。在第一项中，考虑使用两种褐煤蜡和一种酰胺蜡作为分散剂，以促进 CaF2/PET 复合材料的无机和有机组分的增容。为此，通过差示扫描量热法进行了非等温结晶研究。此外，该技术还研究了 CaF2 粒径和浓度对系统热性能的影响。最后，结果的外推已成为一种新型 PET/CaF2 混合复丝。复丝的热性能和机械性能以及分子量也已经过评估。
