Future trends
Various research areas will be of interest in the future (Basu, 2008):
.
multi-function integrated nanocomposite materials, developed in
various ceramic systems in an effort to make significant improvements
in the mechanical and thermal properties of multi-functional structural
ceramic materials for the energy, environment and biomedical sectors
.
development of 'intermaterials': a special class of multi-functional
material containing inorganic, organic and metallic materials, incorpo-
rated at the nano, molecular and atomic levels; new design concepts on
molecular/cluster/lattice-level composites,
their
related results and
impacts on future aspects of research
.
polymer-derived nanostructured ceramics, including the processing of
