Hi

I think it is possible to mix the desired phase change materials, which probably include nanoparticles, fatty acids, etc., into the melted paraffin and use copper particles to increase the thermal conductivity, then combine the mixture with cellulose.

Paraffin, which is the phase change material itself, can be melted to ensure the quality and uniformity of the composition, and after cooling, the phase change material is obtained. But to make a high-performance phase change material, the materials used in it, including paraffin, must be characterized to perform the phase change cycle at the desired temperature.

Metal foams can also be used to further improve thermal conductivity.

Farrokhfar Valizadeh Harzand Thank you for the response.

If I have cellulose as the nanoparticle and to mix with sodium thiosulphate pentahydrate (salt hydrate , PCM) , how can I blend it??? direct hand mixing ?? or making aqueous solution and magnetic stirring?? But cellulose is insoluble in water.... So how can I overcome this problem??

Mix cotton wool with Schweitzer's reagent. Get new stuff. You can modify the cotton fabric as we did

Cellulose solvents are divided into three main methods:

Derivative solvents

Non-derivative solvents

Ionic fluids

Derivative solvents mostly contain concentrated acids, which are not recommended due to the high risks and high probability of decomposition of phase change materials.

Non-derivative solvents include systems that can be soluble through physical intermolecular reactions. One such solvent is ethylene diamine.

It can be the best choice for ionic liquids, as they have excellent solubility and low toxicity.

Cellulose is soluble in some hydrophilic solvents such as 1-butyl-3-methylimidazolium chloride and 1-ethyl-3-methyl-imidazolium chloride without the need for derivatization, and the heating process accelerates the dissolution process.

It seems that the mentioned substances can be used so that first cellulose is added to it and then salt hydrate is added to it.

Farrokhfar Valizadeh Harzand Can yoy please suggest some suitable ionic liquids??

N-methylhexyl imidazolium, dodecyl pyridinium hexafluorophosphate are well-known ionic liquids, but their behavior with the substances to be added should be studied.
