There are different kinds of nano-particles added to Polymer matrix to improve their Mechanical Properties. Which are more practical.
Nanocomposites are a new class of composites. The term “nanocomposite” describes a composite in which the reinforcement has at least one dimension in the range of nanometer (so called nano-reinforcement or nano-particle). Depending on how many dimensions of the nano-particles are in the nanometer range, three types of nanocomposites can be distinguished. The first type is isodimensional nanoparticles, in which the three dimensions of particles are quite similar and are in the order of nanometers, such as spherical silica nanoparticles, and semiconductor nanoclusters. When two dimensions are quite similar and in the nanometer scale and the third one is greater, forming an elongated structure, one speaks about nanotubes or nanofibres, for example, carbon nanotubes or carbon nanofiber. The third type of nano-particles is characterized by only one dimension in the nanometer range. In this case the filler is present in the form of sheets (or lamellar) of one to a few nanometers thick and hundreds to thousands nanometers long such as nano-layered silicates (or nanoclays). This family of nanocomposites can be grouped under the name of polymer-layered silicate nanocomposites.
For adding in Polymer matrix to improve their Mechanical Properties, you may need to consider type of polymer, what mechanical properties that you are looking for. If simply to improve modulus, most of particles can do so. For strength there are interface interaction, aspect ratio of the particles, type of polymer, nano-particles., chemistry of the materials etc.
Hope this will help.
http://www.nanocor.com/tech_sheets.asp - try ask developer or search producer's web page. There is no simple answer for question asked as we can see - different nanoparticles for different polymers for different physical state for different way of preparation.
The nanoparticles can be used with polymer matrix depending on the requirement. For polymers common nanoparticles are nanoclay, Nano metals, nanometal oxides, CNT, graphene, fullerene etc. For ensuring maximum nanoparticle/ polymer interfacial interaction, mostly the nanoparticles are treated chemically, radiochemically or even physically.
Nano particles of Montmorillonite clay, hydroxyapatite,CNT,alumina,silica,zirconia,etc...
These have bright prospects in biomedical applications...
There are several fillers to consider to improve the mechanical performance of a nano-composite: spherical, cylinder-shaped, sheet shaped, nano-clay, etc. The choice may depend on the material symmetry that you want to impart, on the interfacial interaction and on the production technique.
o Theoretical Physics developed (predicted) 'Doping' process is an excellent means of realizing new kind of polymer composites (PMCs) exhibiting characteristic features. And, using nano-fillers diverse PCs can be manufactured based on the application engineering at the molecular level.
o However, TMDCs, graphene derivatives, CNTs, MOs, Rare-Earth Metal Nano particles, Semiconducting Nano particles etc.,of different shapes play the dominant role in engineering the PMCs.
Even nanocellulose could be suitable to increase polymer performance, but you should give us more details: what kind of polymer? what processing technique? what kind of mechanical performance? Stiffness? Toughness? Strength?
