Dear Si
Yes, It is possible. for me I work on carbon black (as conductor charge) laoded in polymer matrix (EAB). If you want many informations about that no problem for me ok .

what does it mean, Herojit Loushambam, when you ask "in a regular pattern"? what regular pattern are you referring to? I would like to make you (and Mohamed) aware of that particles which are smaller than 1 µm will not be dispersed in a statistically even ("regular") distribution, but they are forming *structures" (chains and layers). Please see this link here: http://www2.organic-nanometal.de/Research/abstract/further.html
to understand this, it is necessary to apply non-equilibrium thermodynamics, here is my theory for that:

Dear Bernhard Wessling, thanks for ur communication. By regular pattern i mean is to disperse the nano particles in a uniform manner like that of a mosiac. which will be trap in the void. As crystalline polymers comes into picture is it possible for us to insert the nano particles(the one of my interest) in the interstices of the polymers.
did you read the links I sent you? your statements sound like phantasy, but not like science, sorry.
As you have mention that particles below 1micro meter wont get dispersed in polymer. But if suppose i take a bigger particle then will the particle get disperse.
I want to study the interaction of ferrites disperse in a matrix, since polymers have multi properties, it may give a better response with temperatiure and magnetic field.
sorry, I did not say that particles of smaller than 1 µm do not get dispersed, only: this is not easy, needs to use very well developed dispersion techniques and formulation. As a result, the articles will not be statistically distributed but they form "superstructures" (networks, layers).
Particles bigger than 1 µm can easier be dispersed and the bigger they are, the less structures are formed, and the particles will be more and more statistically evenly distributed, the bigger the particles are (at least from 5 µm onwards)
but as you said "nanoparticles", I assume you wantr to use particles less than 1 µm in size, in fact, *nanoparticles* can only be called like this if their diameter is below 100 nm. These are not at all easy to disperse.
Hi
I think that you need to know which kind of nanoparticles you want to use with which polymers. Then you can try to get good dispersion. As you know Vander walls forces between nanoparticles are very strong. And sometimes it is stronger than repulsive forces. A lot of factors can affect the dispersion like dielectric constant for the polymer. And you need to use strong power to disperse these nanoparticles.
i need to know the distance between the dispersed particles upto a certain extend. i thought i may be able to insert in the interstices of the crystallized polymer. I think it will be very tough to make my conditions to achieved with polymers
I had suggested to read this article: http://www2.organic-nanometal.de/Research/abstract/further.html
for a deeper understanding, add to read this one:
http://www2.organic-nanometal.de/Research/abstract/a-noneq2.html
From there you can also derive some estimation about the distance between the particles.
