The PU-clay nano composite was identified to be a material of high optical transparency, which make them especially attractive for high performance packaging materials, protective films, and high barrier sealants [29]. 

For scratch resistance improvement of organic surfaces also nano-composites are of interest. In a composite nano-scale boehmite or y-aluminia particles of about 15 nm diameter have been used as catalysts for epoxy groups linked to hydrolyseable and condensable silanes. Epoxy polymerization preferably takes place around the nanoparticles and additionally =Si-0-Al= bonds are formed between the silanes and the alumina surface [486]. It seems that the nano-particles, only 5% in volume fraction, are flexibly suspended in an inorganic-organic network. Such systems can be produced as transparent coatings and cured at relatively low temperatures of 90 to 120°C to high performance scratch resistant layers. 

Recently, some other non- conventional ways have been used to prepare zirconia-mullite ceramics [12-17]. In our previous work, nano-zirconia/mullite composite ceramics were prepared by in-situ controlled crystallization from the Si-Al-Zr-0 amorphous bulk, the crystallization kinetics and the general view on the performance were discussed for the first time. In this article, the detail crystallization behavior, structure changes and their effect on mechanical properties for this new nano composite ceramics with high performance have been evaluated.

In this Chapter, we report on some examples of nanocomposites with CNTs, highlighting a meshwork of interactions between the mechanical, electrical and optical properties of CNTs and the interface with the polymer matrix. CNTs are considered ideal materials for reinforcing fibers due to their exceptional mechanical properties. Functionalization of CNTs seems to be the most effective way to incorporate these nanofibers into the polymer matrix. It is generally accepted that the fabrication of high-performance nanotube-polymer composite depends on the efficient load transfer from the host matrix to the tubes. If the percentage of nano-reinforcements is very low or if it is well-dispersed, there are more strong interfaces that slow down the progress of a crack. ...
