“…When nanoparticles are added in the mass of the fibre, the major challenge is the adequate dispersion of nanoparticles into the polymer to prevent their aggregation. Among the possible methods to introduce nanoparticles in the fibres (2,3,4,5,6,7,8), the meltblending process is the more commercially attractive due to its versatility, although agglomeration of nanoparticles can occur. To prevent agglomeration, the surface of the nanoparticles can be modified through bonding organic components on its surface, yielding anchorage or bonding capacity with the polymer (9), or including a dispersing agent in the mixture.…”

This work is based on the analysis of the influence of dispersing agents on the non-isothermal kinetics, thermomechanical behaviour and dispersing action of PET/TiO 2 nanocomposites. The influence of two montanic waxes and an amide wax used as dispersing agents in the nucleating effect of the nanoparticles is studied. The dispersing agents are the following: a) a partly saponified ester of montanic acids (PSEMA), b) an ester of montanic acids with multifunctional alcohols (MAWMA) and c) an amide wax based on N,N'-Bisstearoyl ethylenediamine (AW). The non-isothermal kinetics based on the Avrami method revealed that MAWMA and PSEMA favours the nucleating effect of the nanoparticles when are included in PET. Birefringence microscopy points out the good dispersing capacity of MAWMA and AW and the termomechanical analysis confirmed that the ester of montanic acids with multifunctional alcohols MAWMA shows the best dispersing properties and best promotes the nucleating effect of the TiO 2 nanoparticles when used for PET/TiO 2 nanocomposites production.

“…Again, PET fibres are mainly used in textile industry (Bhata and Naik 1984;Patel and Bal 2001). Apart from that, it is also used in the field of surgical polymeric textiles (Phaneuf et al 1997;Ferreira et al 2002;Metzger 2003), composites (Fu et al 2002), nanocomposites (Chang et al 2004), conducting polymer (Mishra et al 2000), electroactive polymer (Patel and Mallick 2000) etc. Polyesters are mainly cross-linked when irradiated (Kuleznev and Shershnev 1990).…”

Abstract. Microstresses developed in the crystallites of polymeric material due to irradiation of high-energy particle causes peak broadening and shifting of X-ray diffraction lines to lower angle. Neutron irradiation significantly changes the material properties by displacement of lattice atoms and the generation of helium and hydrogen by nuclear transmutation. Another important aspect of neutron irradiation is that the fast neutron can produce dense ionization at deep levels in the materials. The polyethylene terephthalate (PET) fibre of raw denier value, 78⋅ ⋅2, were irradiated by fast neutron of energy, 4⋅ ⋅44 MeV, at different fluences ranging from 1 × × 10 9 n/cm 2 to 1 × × 10 12 n/cm 2 . In the present work, the radiation heating microstresses developed in PET micro-crystallites was investigated applying X'Pert-MPD Philips Analytical X-ray diffractometer and the effects of microstresses in tensile strength of fibre measured by Instron have also been reported. The shift of 0⋅ ⋅45 cm -1 in the Raman peak position of 1614⋅ ⋅65 cm -1 to a higher value confirmed the development of microstresses due to neutron irradiation using micro-Raman technique. The defects due to irradiation were observed by SEM micrographs of single fibre for virgin and all irradiated samples.

“…All the samples were prepared by a conventional 2-step polycondensation [6,25]. In a typical procedure for the preparation of PET/LDH nanocomposites, TA intercalated LDHs were previously dispersed in ethylene glycol (EG, 1 mol) using a sonicating homogenizer for 15 min.…”

Abstract. Terephthalate (TA) intercalated layered double hydroxides (LDHs) were synthesized using hydroxides as raw materials, and poly(ethylene terephthalate) (PET)/LDH nanocomposites with different contents of TA intercalated LDHs were prepared by in-situ polymerization. The structure, morphology and thermal property of PET/LDH nanocomposites were investigated. The TA intercalated LDHs were partially exfoliated and well dispersed in PET matrix. The PET/LDH nanocomposites exhibit enhanced thermal stability relative to pure PET, confirmed by the thermogravimetric analysis results. The results of differential scanning calorimetry suggest that LDH nanoparticles could effectively promote the nucleation and crystallization of PET.
