Nanoparticles nano-fibres

As with advanced polymer composite, a nanocomposite is formed from the combination of two or more materials however, one of the materials has nanoscale (< 100 nm) dimensions. Nanoparticles can be classified into three categories depending on the number of their nanoscale dimensions (i) nano-spheres (ii) nano-fibres and (iii) nano-plates, having three, two and one nanoscale dimension, respectively, Thostenson et al. (2005). Paul and Robeson (2008) have given a comprehensive review of nanoparticles. Only nano-fibres and nano-plates will be mentioned in this chapter, as these are relevant to possible structures concerned with sustainable energy. 

In view of this, nano titanium dioxide was synthesized and prepared as suspension with PVP solution. The mixture was set to electro-spin into fibre at 18KV. The e-spun fibre was subjected to differential thermal analysis to obtain the sintering profile for the titania fibre. The titania fibre was sintered at 500°C and 1200°C. The sintered phases and microstructural of titania fibre were analysed by using X-ray diffractometer and scanning electron microscope and presented. The cross-linked titania fibre formed a web-like structure maybe reduced the nano risk as compared to the nanoparticles.

There is a wide variety of both synthetic and natural crystalline fillers that are able, under specific conditions, to influence the properties of PP. In PP nanocomposites, particles are dispersed on the nano-scale. " The incorporation of one-, two- and three-dimensional nanoparticles, e.g. layered clays, nanotubes, nanofibres, metal-containing nanoparticles, carbon black, etc. is used to prepare nanocomposite fibres. However, the preparation of nanofilled fibres offers several possibilities, such as the creation of nanocomposite fibres by dispersing of nanoparticles into polymer solutions, the polymer melt blending of nanoparticles, in situ prepared nanoparticles within a polymeric substrate (e.g. PP/silica nanocomposites prepared in situ via sol-gel reaction), " the intercalative polymerization of the monomer.
