“…A decrease in Tg was explained by an increase of free volume with a higher delamination of silicate layers while smaller surface area of tactoids causing weak interactions with the polymer matrix resulting in decrease in free volume was the reason for an increase in Tg [35]. As for the findings in the literature regarding melting temperature (Tm), Phang et al (2004), Wang et al (2006), Frounchi and Dourbash, Kracalik et al and Calderas et al determined that the melting point increased as a result of organoclay addition [15, 21, 25, 35, 45]. On the other hand, most of the researchers determined a reduction in cold crystallisation temperature (Tc) values [2, 5, 15, 16, 21, 22, 27].…”

Today, the production of polymeric nanocomposite materials is one of the most important research fields. In this study, it was aimed to investigate the effect of organoclay particles on recycled polyester (rPET) fibre properties. In the literature, the studies mostly concerned with the engineering plastic applications, and hence the investigations were done on pellet and injection-moulded rPET/organoclay nanocomposite samples. Actually, fibre application is the most important market for PET wastes, but unfortunately, there are only a few papers regarding rPET/organoclay composite fibre properties. In the study, rPET/organoclay nanocomposites were prepared by melt intercalation process with different modified organoclay types (3 wt-%), and multifilament fibres were spun by the melt spinning method. Morphological and thermal properties of nanocomposites and surface structure, tensile, and thermal stability properties of the fibres were tested. The results indicated that the distribution of clay particles and organoclay types had a significant influence on various fibres properties.

This chapter deals with the properties and applications oλ clay mineral water dispersions and clay minerals as λlame retardant additives λor polymers. Clay minerals, such as kaolinites, micas, and smectites, are the basic constituents oλ clay raw materials, which are classically employed in the ceramic industry to produce porcelain, λine ceramics, coarse ceramics, cements, electro-ceramics, tiles and reλractories. These products are mainly used in sectors oλ economic importance, such as aμriculture, civil enμineerinμ, and environment. " direct method to prepare clay mineral polymer composites is throuμh dispersion in water. Water dispersions oλ clay exhibit some interestinμ λlow phenomena such as yield stress i.e., the material behaves as a solid until a critical λorce applied on the material λorces it to λlow. Water dispersions oλ clay have also been reported to be used to prepare materials with enhanced λlame-retardant properties such as leather. On the other hand, direct melt compoundinμ oλ clay mineral with diλλerent polymers as the composite matrix HIPS, PP, and HDPE to prepare a number oλ polymer composites with λlame-retardant properties has also been reported.
