PH 7.8 Tris(Hydroxymethyl)Aminomethane Preparation Composite Phase Change Materials

As a common biological buffer, TRIS (full name trishydroxymethylaminomethane) is not only widely used as a solvent for nucleic acids and proteins, but also one of the main components of protein electrophoresis buffers. It can also produce a variety of chemicals, pesticides, and pharmaceuticals. The product 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.

Configuration of Tris buffer solution

Phase change materials refer to substances that change the state of matter with temperature changes and can provide latent heat. When the physical state changes, the temperature of the material itself remains almost unchanged before the phase change is completed, forming a wide temperature platform, but the latent heat absorbed or released is quite large.

Tris(hydroxymethyl)aminomethane is a heat storage material with excellent heat storage performance, large latent heat value and good application performance. However, when it is heated to a solid-solid phase transition temperature and above, it will change from a crystalline solid to a plastic crystal. It has a high solid vapor pressure, is very volatile, has poor stability, high cost, and high equipment requirements. These shortcomings need to be overcome to be better used in actual production and life.

TRIS base powder

Technicians use the solution immersion method to fill the tris hydroxymethylaminomethane into porous silica gel with a pore size ranging from 15 to 100 nm and porous glass with a pore size ranging from 12 to 100 nm to prepare a composite energy storage material. There are four specific preparation methods:

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

2. Add 4 times the mass ratio of deionized water as a solvent, and dissolve in a 363K water bath;

3. Keep the water bath to volatilize the solvent, and stir to maintain the uniformity of the solution;

4. Until the solvent evaporates, the solute will completely remain in the pores to achieve the filling effect.

The morphology and heat storage performance of the two composite materials obtained were characterized by scanning electron microscopy, X-ray powder diffraction, differential scanning calorimeter, etc., and the space limitation of nanometer size affected the performance of tris The heat storage properties have significantly improved the phase change temperature, latent heat of phase change, subcooling, and thermal cycling performance of the composite phase change material.

Phase change materials have shown broad application prospects in solar energy utilization, electronic devices, medical and health products, aviation and aerospace equipment, and building energy conservation. The modified composite material solves the problems of tris alone use, improves the application performance of conventional phase change materials, and enables composite phase change materials to have a wider temperature control range and more accurate heat storage capacity And the more sensitive temperature response makes it possible to be applied in real life.
