can nanoparticle introduce into the wax for the purpose of increase the latent heat and decrease ethe melting point of the wax
Dear Veeramanikandan,
Your question is very interesting but very generalised.
Yes, generally it is possible to add nanoparticles in wax.
But how will it effect the latent heat of wax depends on various factors such as;
1) Wax type, Carbon chai length and so on,
2) Which nanoparticles you are using,
3) Size, morphology and crystallographic features of your nanoparticles,
4) How to add the nanoparticles, (you may have to heat the wax first at certain temp. and sometime you have to use some surfactants
But I am not sure how you will control the stability/ homogeneity of your nanoparticle in wax system??
We are working on improving the heat capacities and thermal properties of paraffin by blending various types of nanoparticle, and I can share the article with you soon.
All the best

Yes, it is possible Mr.Veeramanikandan. But due to the addition of nanoparticle in the may give positive or negative result

According to Raoult's law a solution of stearic acid in carnauba wax will crystallize below melting temperature of wax 82 degrees Celsius, depending on the concentration of stearic acid. Dispersion system can be prepared with a higher latent heat than that of the carnauba wax (115 kJ/kg). Such compositions ( wax + acid +nanoparticles Cu (213 kJ/kg)) in solid state stable, but in the liquid state, they are stratified.
