TLDR
In this article, the influence of nanoclays on the physical properties of polyethylene terephthalate (PET) nanocomposites was investigated, and it was observed that the effect of nanoparticles on the crystallization of PET is more considerable than TiO2 nanoparticles.Abstract:
The influence of spherical (titanium dioxide (TiO2)) and platelet-like (Closite20A) nanofillers on the physical properties of polyethylene terephthalate (PET) nanocomposites was investigated. PET nanocomposites were prepared by melt blending of PET and nanofillers. Differential scanning calorimetry showed that PET nanocomposites had higher crystallinity than the neat PET, possibly due to the nucleating role of the nanoparticles. It was observed that the influence of nanoclays on crystallization of PET is more considerable than TiO2 nanoparticles. For PET/TiO2 and PET/clay nanocomposites, the highest value of crystallinity observed at 3 wt% and 1 wt% loading level of TiO2 and Closite20Ananoparticles, respectively. Scanning electron microscopic micrographs showed that uniform distribution and good dispersion of TiO2 through PET matrix were achieved at 1 and 3 wt% loadings but at higher loadings up to 5 wt%, nanoparticles tend to accumulate. Transmission electron microscopy and wide angle X-ray diffraction s...read more

Nanocomposite Materials for Food Packaging Applications: Characterization and Safety Evaluation
Abstract: Food packaging requires long shelf life and the monitoring of safety and quality based on international standards. In the past decade, polymer nanocomposites have emerged as a new class of food packaging materials, because they have several advantages, such as enhanced mechanical, thermal, and barrier properties. The larger surface area of nanoparticles compared with their microscale counterparts favours filler–matrix interactions and the performance of the resulting material. A new technology is accepted by the community once it has been tested for its effects on health. There have been some studies on the migration of nanoparticles from packaging material into food/food simulants during storage. It is very important to evaluate the safety of nanocomposite packaging materials used for food products. This review summarizes the characteristics and properties of nanocomposite packaging materials along with their safety problems for food consumers.

Comparative study of the effects of anatase and rutile titanium dioxide nanoparticles on the structure and properties of waterborne polyurethane
TL;DR: In this paper, the effects of anatase and rutile titanium dioxide (TiO 2 ) on the structure and properties of hybrid films were comparatively studied and the results showed that the incorporation of nano-TiO2 into WPU can highly improve the UV protection ability, mechanical property, photocatalytic ability and antifungal capacity of the hybrid films.

Polymer Layered Silicate Nanocomposites
TL;DR: In this paper, a new, versatile and environmentally benign synthesis approach by polymer melt intercalation is discussed. But, unlike in-situ polymerization and solution inter-calation, melt interalation involves mixing the layered silicates with the polymer and heating the mixture above the softening point of the polymer.
