Tris (full name trimethylamine) is a common biological buffer, which is not only widely used in nucleic acid and protein solvents, but also one of the main components of protein electrophoresis buffer, but also can produce a variety of chemical, pesticide and pharmaceutical products, and is an important intermediate for the preparation of surfactants, vulcanization accelerators and some drugs. In addition, it can also be used to prepare composite phase change materials.

  Phase change material is a material that changes the state of material and can provide latent heat with the change of temperature. When the physical state changes, the temperature of the material itself is almost unchanged before the phase transition is completed, forming a wide temperature platform, but the latent heat absorbed or released is quite large. Trimethylamine methane is a kind of heat storage material with excellent heat storage performance, which has a large latent heat value and good application performance. However, when heated to the solid-solid transition temperature and above, it will change from crystalline solid to plastic crystal, with high solid vapor pressure, very volatile loss, poor stability, high cost and high equipment requirements. It is necessary to overcome these shortcomings to be better applied in the actual production and life.

The technicians used the solution impregnation method to fill the trimethyl methyl methane into porous silica gel with the pore size range of *****0nm and porous glass with the pore size range of *****0nm to prepare the composite energy storage material. The specific preparation methods are as follows:

1. Determine the mass ratio according to the filling rate and the pore volume of the hole material, weigh and mix them in the glass tube;

2. Add 4 times of deionized water as solvent, **3k water bath, dissolve;

3. The solvent volatilized by continuous water bath and the solution uniformity was kept by stirring;

4. Until the solvent evaporates, the solute is completely left in the pore, and the filling effect is achieved.

The morphology and thermal storage properties of the two composites were characterized by SEM, XRD and DSC. The space limit of nano size affected the thermal storage properties of trimethylamine methane, which made the phase change temperature, latent heat, supercooling and thermal cycling performance of the composite materials improved significantly.

Phase change materials have a wide application prospect in solar energy utilization, electronic devices, medical and health products, aviation and space equipment, building energy saving and so on. The modified composite solves the problems existing in the use of trimethylaminomethane alone, improves the application performance of conventional phase change materials, makes the composite phase change materials have a wider temperature control range, more accurate heat storage capacity and more sensitive temperature response, which makes it possible to apply it in real life.
