Nanotechnology carbon black

Biopolymers have diverse roles to play in the advancement of green nanotechnology. Nanosized derivatives of polysaccharides like starch and cellulose can be synthesized in bulk and can be used for the development of bionanocomposites. They can be promising substitutes of environment pollutant carbon black for reinforcement of rubbers even at higher loadings (upto SOphr) via commercially viable process. The combined effect of size reduction and organic modification improves filler-matrix adhesion and in turn the performance of polysaccharides. The study opens up a new and green alternative for reinforcement of rubbers.

The application of a classic method of size enlargement for the processing of nanoparticles, that is already in use since a time when nanotechnology was not even defined yet, shall be mentioned as a final example. It has been described above that nanosized solids feature an extremely low bulk density caused by their almost instantaneous adhesion and formation of loose floes. Such materials also tend to dusting and exhibit many other unfavorable characteristics. This is also true for industrial carbon black that has been produced in flame reactors for more than half a century... 

Carbon nanotubes (single-wall and multiwall) were purchased from Helix Material (Richardson, Texas), Carbolex (Broomall, PA), and Carbon Nanotechnologies Incorporation (CNI, Houston, Texas, now Unidym Inc). The carbon nanombes were used as received without any further purification or functionalization. Therefore, there are some impurities such as carbon black and metal in the samples.
