Improving Performance Properties

An aluminum zinc phosphate is produced by coprecipitation of primary aluminum phosphate (A1(H2P04)3) with zinc oxide. Such pigments have a higher phosphate content than standard zinc phosphate. The improved performance properties are attributed to this higher phosphate content [5.85]. 

During research for anticorrosive pigments with improved performance properties compared to zinc phosphate, the development of so-caUed modified polyphosphate pigments was a further focus.

Nanocomposites materials can be defined as composite materials, that combine one or more separate components in order to improve performance properties, for which at least one dimension of the dispersed particles is in the nanometer range [23]. In polymer clay nanocomposites, nanoscale particles have typically 10-100 nm in size [24]. Depending on the reinforcement, remarkable improvement in material properties when compared with neat polymer or conventional micro and macro-composites can be obtained. These improvements can include high moduli, increased strength and heat resistance, decreased gas permeability and flammability, and increased biodegradability of biodegradable polymers [25].

As it has been outlined in the introduction to this chapter, blending can be an interesting tool to improve performance properties of a material. Some attempts have been made by Mending with PMMA to meet this objective with respect to the electroaclivity of PVDF. The background of these works is that ... 

There can be reinforcements added to polymeric matrices such as cellulosic fibers, and fillers such as titanium dioxide incorporated into roll thermoplastics, to improve performance properties or reduce cost bases. These host matrices can include polypropylene, polyethylene, polystyrene, polyamide, and PVC to name a few. In these circumstances, the addition of dispersants and/or coupling agents is needed to attract the more highly polar fibers and fillers to the less polar polymer matrix. These added constituents will form a level of presence (depending upon their inclusion ratio relative to the bulk) at the composite surface which must be considered relative to atmospheric plasma chemistry prescription. 

The formulation of dyes with regard to the substrate is critical to successful dye adhesion. Dye formulations have evolved from natural forms to synthetics because the latter offer lower cost, a greater color gamut, and improved performance properties delivered to substrates. Synthetic dyes generally have a strong affinity to substrates to be dyed, but that does not guarantee that adhesion promotion is not required. On the contrary, there are a multitude of dye applications where colorfastness is only possible with the addition of a promoter or mordant (etchant). Each dye must therefore be examined relative to how they are utilized in order to prescribe the most successful protocol for adhesion.
