Hello Friends,I am doing research on Hybrid green nancomposites for exterior structure parts of automotive. I m using fiber, poly(trimethylene terephthalat) , nanoclay.Is their any other way???Is there anyone has done work in same field want to share his experience.RegardsArun Kumar Gupta.
Read more…The metalic, ceramic or carbon-based nanoparticles are of great interest in terms of their potential applications in biomedical, electronic, and opticalmaterials. The incorporation of these nanoparticles in polymer matrices is a field of particular interest for materials engineering and the study of nanoparticle-matrix interactions.The process of dispersing nanoparticles in a polymer matrix so that they remain isolated (i.e., dispersed) has proven to be problematic. Three general methods to…

Properties which have been shown to undergo substantial improvements include:· Mechanical properties e.g. strength, modulus and dimensional stability· Decreased permeability to gases, water and hydrocarbons· Thermal stability and heat distortion temperature· Flame…

Your question is very interested. The influence of the ultrasound waves on the strength of CNTs depends of the following parameters:
1.- Medium
2.- Power of the ultrasound waves (Amplitude)
3.- Frequency
4.- Time of exposition to the ultrasound waves
5.- Lenght of the CNTs.
For example, if the ultrasound waves travel in a low viscosity medium, the attenuation of the waves will be lower than a high viscosityu medium; thus, if the amplitude of the ultrasound waves in that low viscosity medium is high enough, and if the lenght of the CNTs is too, the CNTs will experiment a rupture of their bonds, therefore, the strength of the CNTs will be affected.
There is a good article that explains how the influence of several parameters can influence on the mechanical properties of CNTs:

Does sonication weakens not the strength of SWCNT but it can separate CNT of MWCNT
Does sonication weakens the strength of carbon nanotubes?
It offers a free open access Nano Archive of nearly 7,000 items including many full texts at http://www.nanoarchive.org. Please contact me if you would like to archive your research and I will create an editor's account for you.
You can join the international network at http://www.icpc-nanonet.org. Registration is free. The website also contains information for parties interested in FP7 collaboration, details of free webinars taking place (three in September), information about researchers and organisations and much more.
I am also interested in communicating with researchers in sub-Saharan Africa for the annual region report. If you would like your institution's research showcased in the report, please get in touch.
This is Marslin Gregory, Doing my PhD, I am working on Polymer Nanoparicles Drug Delivery and imaging. Its appreciable If I get the contact from some one working the same platform.
