Create three-dimensional network of siloxane polymer in the epoxy resin is an appropriate mechanical properties .Dispersion of nanoclay in these coating was prepared by ultrasonication method. Mechanical properties of nanocomposit coatings such as abrasion, hardness and adhesion was increased by addition of nanoclay montmorillonite. Different percentages of nanoclay in coating showed that even ...

The search for renewable biodegradable materials to replace conventional oil-based plastics is a fast-growing research area as it provides an important factor the sustainable growth of packaging industry. In this regard, clay-containing composite have numerous current and potential commercial applications. However, interaction between clay polymer, i.e. Poly(ethylene glycol), influenced by many...

Polylactide (PLA) is viewed as a potential material to replace synthetic plastics (e.g., poly(ethylene terephthalate) (PET)) in food packaging, and there have been a number of developments in this direction. However, for PLA to be competitive in more demanding uses such as the packaging of oxygen-sensitive foods, the oxygen permeability coefficient (OP) needs to be reduced by a factor of ~10. T...

Abstract When suspensions are exposed to shear forces, the particles may form ordered structures depending on their shapes, concentrations, and material. For some processes, e.g., for wet-film coating, it is important know how fast these in fields long persist when relaxed. To obtain information particle structure formation decay time, effective viscosity of nematic Na-hectorite nanosheets was ...

This study presents a new bionanocomposite coating on poly(ethylene terephthalate) (PET) made of pullulan and synthetic mica. Mica nanolayers have a very high aspect ratio (α), at levels much greater than that of conventional exfoliated clay layers (e.g., montmorillonite). A very small amount of mica (0.02 wt %, which is ϕ ≈ 0.00008) in pullulan coatings dramatically improved the oxygen barrier...

A long-lasting barrier protection at damaged sites of coated system can be achieved by means of an active response of the primer. This may be attained through the release of reactive liquids from dispersed containers, the increase of the local mobility of the polymeric network, or the expansion of (dispersed elements in) the primer [1]. Such self-healing mechanisms provide an excellent strategy...
