This work presents an investigation of the properties of poly(ethylene terephthalate)/glass fibres/nanoclay multiscale composites. The aim is to demonstrate the effect of adding various clay amounts on the morphology and mechanical performance of multiscale PET composites. Multiscale composites were prepared by adding 0.5, 1.0, 3.0, and 5.0 wt% of...

... shaped specimens were moulded by injection process, using a Ferromatik-Milacron K85 machine. The injection conditions have been fixed according to the material data sheet, which sum up is in Table 1. Throughout the paper, the numbers following the designation PET and NC in sample names, indicate the weight percentage of each constituent in the sample. ...

An extensional flow mixture (EFM) system was studied, with the goal of achieving better distributive and dispersive mixing. The effects of different mixing strategies (masterbatch method (MB), polyethylene-grafted maleic anhydride (PE-g-MA) as a compatibilizer, and compounding devices, such as a single screw extruder (SSE), a twin screw extruder (T...

... In case of phosphonium modified PET nanocomposites, there is a significant enhancement of modulus when clay incorporates into the polymer matrix because of higher modulus of clay compared to polymer [32]. Tensile modulus is useful mechanical property of a material that actually measures the stiffness i.e., how much material deform when subjected to a particular load. ...
The rapid development of nanotechnology has made it possible to come up with new ways to sense and package food that can help solve long-standing problems in the food industry. These problems include extending shelf life, reducing waste, determining food safety, and increasing food quality. In packaged foods, nanomaterials could be employed to improve mechanical stability, gas barrier characteristics, water repellency, antimicrobial and scavenging capabilities. These materials can indeed be employed in biological and chemical sensing devices, which makes it possible to make very sensitive devices for determining how fresh food is and detecting allergies, toxins, and harmful contaminants. This chapter summarizes current research about the use of nanomaterials in the progression of (1) (bio) sensors that can detect nutrients and non-nutrients, antioxidants, adulterants, and toxins, (2) ways to progress the barrier and structural content of packaged food products, and (3) smart packaging that can be used to make food more active. In the food sector, nanomaterials include environment, healthcare, and safety implications, as well as an overview of regulation and consumer opinion.

This chapter provides a comprehensive overview of clay-based PET nanocomposites. The different methods applied to prepare clay-based PET nanocomposites, their morphological and structural interpretation, improvements in mechanical and material characteristics, melt-state rheological and crystallization behavioural patterns, and, subsequently, current PET-based clay nanocomposites materials applications are all discussed.
