How can I perform TGA and TMA on nano composites? How can I measure physical and chemical properties for varies temperature? What are the different mechanical properties can be verified at varying temperature?
Dear Sir,
TGA testing can be done using 1cm square specimen.
you can get thermal degradation behaviour for the nanocomposites
for simple understanding you can do DSC test

Absolutely, in our group in TCD we've been doing this for nearly 20 years. For TGA, you just need ~2-5mg of sample, ideally flat. The sample can be run in air of in nitrogen, depending on thermal reactivity and may take ~1 1/2 hours. DMTA is more useful for the mechanical studies and there is anISO standard sample shape for the mechanical analysis. This technique is also potentially more accurate than using DSC for thermal analysis, this saving you time.
Using DMA in mechanical analysis, you can compare nanocomposites with several ratio of fillers and neat samples in terms of static and dynamic test program for examle Tg, tangent delta, storage modulus and loss modulus. There are a lot of original research paper related to this.
Answering on your questions I can mark that the main idea for the nano composites study is that it does not matter the presence "nano" in the name. Therefore, it is possible to apply the same methods as for the "normal" polymeric materials. There are too many properties that can be studied. It all depends on your particular situation. Or real "super-task" stands before you and you want to know which equipment is needed for its solution. Or you have a set of devices and want to understand what properties of nano composites you can study with them
Pls, ask your question in a more specific form
.
In case of nanocomposites, usually you use the reinforcement material as nanomaterial. In means matrix in bulk form. Of you can say ultimately at the end you will have some thing visible to naked eye and tangible, whether you started from nano or micro. So you can use these techniques on these composite materials. Please, throw away this concept that the same techniques can not be used for nanocomposites too. There are few properties which are to be measured at nano level scale can be done by some specific technique.
