“…The thermal conductivity of plasters represents an important parameter for building designers, especially in the case of PCM composites. The results provided by Karkri et al [30] highlighted that a lowered coefficient of thermal conductivity of the support material matrix is the limiting factor for PCM utilization in building practice.…”

Thermal energy storage systems based on latent heat utilization represent a promising way to achieve building sustainability and energy efficiency. The application of phase change materials (PCMs) can substantially improve the thermal performance of building envelopes, decrease the energy consumption, and support the thermal comfort maintenance, especially during peak periods. On this account, the newly formed form-stable PCM (FSPCM) based on diatomite impregnated by dodecanol is used as an admixture for design of interior plasters with enhanced thermal storage capability. In this study, the effect of FSPCM admixture on functional properties of plasters enriched by 8, 16 and 24 wt.% is determined. On this account, the assessment of physical, thermal, hygric, and mechanical properties is done in order to correlate obtained results with applied FSPCM dosages. Achieved results reveal only a minor influence of applied FSPCM admixture on material properties when compared to negative impacts of commercially produced PCMs. The differential scanning calorimetry discloses variations of the phase change temperature, which ranging from 20.75 °C to 21.68 °C and the effective heat capacity increased up to 15.38 J/g accordingly to the applied FSPCM dosages.

“…To solve the leakage issue, many encapsulation technologies, which can divided into encapsulation and composite technology, were developed [9][10][11]. Karkri et al [12] pointed that one possible method for suppressing leaching is based on the microencapsulation of wax within a polymeric shell. Encapsulation of PCM is a kind of technology that PCM is covered by film forming material (capsule wall) to become tiny particles.…”

During this study, paraffin wax with low melting point was encapsulated in a urea-formaldehyde resin to prepare a novel microencapsulated phase change material (Micro-P6) for temperature regulation and thermal energy storage. The structure and properties of Micro-P6 were characterized by using Fourier transform infrared spectroscopy, differential scanning calorimeter, laser particle size analyzer, thermogravimetric analysis, contact angle analysis, and scanning electron microscope. The results indicated that the chemical structure of Micro-P6 meets the designed core-shell structure; and the paraffin wax with low melting point was successfully encapsulated by using urea-formaldehyde resin; and the Micro-P6 shows a spherical structure and rough surface, and the average size is 8.0-10.0 μm. Then, the performances of Micro-P6, such as core content, mechanical property, thermal conductivity and durability, were tested. Based on above characterization and performance test, it was indicated that the synthesized Micro-P6 could be used in the field of cementing and construction for temperature regulation and thermal energy storage. The applications of Micro-P6 in the field of cementing and construction will be completed in our next study.
