In the field of nanotechnology, the synthesis and applications of polymer nanocomposites are an important and strategical field of nanomaterial science.
Polymer nanocomposites respresent a new class of material alternative to conventional filled polymers.
In this new class of material, nanosized inorganic filler (at least one dimension) are dispersed in polymer matrix offering tremendous improvement in performance properties of the polymer.
Typically smectite-type clays are used as fillers. Montmorillonite and hectorite layered structure are dispersed in polymer matrix.
According with the bonding scenariuos between polymer chain and silicate layer, new material shows excellent mechanical properties compared to neat polymer: superior mechanical characteristics higher tensile strength (40% increase), heat resistance and chemical resistance. http://www.nanocompositech.com
Nanotechnology is the understanding and control of matter at dimensions of roughly 1 to 100 nanometers, where unique phenomena enable novel applications. Encompassing nanoscale science, engineering and technology, nanotechnology involves imaging, measuring, modeling, and manipulating matter at this length scale.
At the nanoscale, the physical, chemical, and biological properties of materials differ in fundamental and valuable ways from the properties of individual atoms and molecules or bulk matter.
The field of nanocomposites involves the study of multiphase material where at least
one of the constituent phases has one dimension less than 100 nm. The promise of nanocomposites lies in their multifunctionality, the possibility of realizing unique combinations of properties unachievable with traditional materials.
This ability to tailor composites by using nanosize building blocks of heterogeneous chemical species has been demonstrated in several interdisciplinary fields.
Recently, nanoscale filled polymer composites in which the filler is <100 nm in at least one dimension was instead of traditional micrometer-scale polymer composites.
