Unusual Ceramic Dielectrics and Conductors

Several types of continuous ceramic fibres are used here. Fibres made of -type glass s ( 2. Tradition continued. The silica tradition) in composites used for constmction of boats, carbon fibres (Fig. 3.12) in composites used for aviation and sports equipment. Materials other than the continuous fibres can also be applied. Namely, particles where at least one dimension is <100 nm, like clay minerals ( 2. The tradition continued. The clay tradition), carbon nanombes and graphenes (—> 5. Unusual ceramic dielectrics and conductors). Due to a high ratio of length to thickness such fillers are in contact with the polymer matrix over a large area. Therefore, their effect on strength and fracture toughness—can be observed even with a low-volume fractions of fillers (firom 0.5 to 15 %wt). Due to the dimensions of these fillers, these composites are often referred to as nanocomposites. 

The trend to miniaturise semiconductor devices continues. It is believed that, a broader use of ferroelectrics, carbon nanotubes and grapheme ( 5. Unusual dielectrics and ceramic conductors), further miniaturisation and ease of switching of semiconductor transistors and diodes can be made possible.
