Nowadays, the increase in energy demand have resulted in supply difficulties,
exhaustion of energy resources, climate change and environmental pollution.
These concerns have urged society to effective use of energy and reduce the
impact of their activities over nature. Energy consumption may be classified in
function of their use. A great fraction comes the energy required by buildings
mainly due to the population growth and the time people spend
indoor. Therefore, it is necessary to focus on the design and synthesis of new
construction materials to aboard this energy consumption issue. A way to attain
a reduction in buildings energy requirements and contribute to the
improvement of the surrounding environment is by using a thermal energy
storage system. Phase change materials (PCMs) which are based on latent heat
storage, are the most promising technique due to their high-energy storage
density and small storage/retrieval temperature change. PCM’s works on the
principle that as the temperature increases, the material stores energy by
changing its phase solid to liquid. Geopolymers can be functionalized as it can
be found in the literature. Some industrial by-products and construction waste
materials can be employed for their manufacture. They are synthesized at low
and the final product is an amorphous structure which size and porous density
can be tailored by changing the temperature synthesis. This gives an advantage
if it is considered that PCM’s can be confined inside the geopolymer by
impregnation. In the present work, geopolymers were impregnated with 1-
dodecanol as a widely used PCM. The samples were synthesized at 40 and 90 °C
to modify their porosity and it was assessed the effect of adding a surfactant to
increase the adsorption capacity of geopolymers. The final samples were
characterized by SEM, FT-IR, BET and XRD. The thermal energy storage capacity
was determined by Differential Scattering Calorimetry.
