“…Figure 13 shows the response of the composite PCMs to temperature change. Similarly, with CVL/BPA/TD as thermochromic PCMs and bamboo with lignin as support materials, Heng et al [ 88 ] developed a new type of thermochromic bamboo-based composite PCMs by vacuum impregnation, which underwent phase change at 40.8 °C and had a latent heat of 113.3 J/g. In the range of 25–60 °C, the total color difference of the composite PCMs changed with temperature, and the discoloration temperature was about 40 °C, consistent with the DSC results.…”

Phase change materials (PCMs) can store/release heat from/to the external environment through their own phase change, which can reduce the imbalance between energy supply and demand and improve the effective utilization of energy. Biomass materials are abundant in reserves, from a wide range of sources, and most of them have a natural pore structure, which is a good carrier of phase change materials. Biomass-based composite phase change materials and their derived ones are superior to traditional phase change materials due to their ability to overcome the leakage of phase change materials during solid–liquid change. This paper reviews the basic properties, phase change characteristics, and binding methods of several phase change materials (polyethylene glycols, paraffins, and fatty acids) that are commonly compounded with biomass materials. On this basis, it summarizes the preparation methods of biomass-based composite phase change materials, including porous adsorption, microencapsulation based on biomass shell, and grafting by copolymerization and also analyzes the characteristics of each method. Finally, the paper introduces the latest research progress of multifunctional biomass-based composite phase change materials capable of energy storage and outlines the challenges and future research and development priorities in this field.

“…The healing agent incorporated in thermal barrier coatings should have some properties [106] including:1) it should be in the solid phase at the operating temperature because liquids have a large thermal conductivity and large TEC; 2) it should be turned into a liquid to wet the crack surfaces and fill the crack; 3) the liquid medium should turn into a solid phase by the reaction between the TBC material and the liquid phase through a solid-state chemical reaction. As a result of this process, the crack is healed by a well-bonded crystalline material having low thermal conductivity [107].…”

To improve the hot section metallic parts durability in advanced gas-turbine operating in power generation and aircraft, thermal barrier coating (TBCs) are extensively utilized to increase their lifetime. The reason for applying coatings on these components is the improvement of their physical properties, mechanical properties, and outer look. The self-repairing ability of materials is very promising due to expanding the service time of materials and it is also beneficial in terms of human safety and financial aspects. In this review article, structure, properties, limitations, and the modification approaches of TBCs were studied. In addition, self-healing agents for TBCs including SiC, MoSi 2 , TiC were introduced, which release their oxide by reaction with air and O 2 that are able to heal the pores/cracks in the coatings. In this regard, their coating methods, mechanism, and applications in TBCs were reviewed.

Preparation and characterization of some new thermochromic microcapsules with surface reactivity, material safety and their incorporation to cotton, and wool fabrics were performed in this work. Poly(methyl methacrylate-comethacrylic acid) P(MMA-co-MAA) was the shell of microencapsulated thermochromic system (TS). The TS acting as a core substance consisted of n-tetradecanol (TD) as solvent, crystal violet lactone (CVL) as a leuco dye and phenolphthalein (PP) as color developer. Particle photographs and average size distribution were evaluated using scanning electron microscopy (SEM) and particle size instruments, respectively. Microcapsules morphology was spherical and particle size average was 13.67 μm. Thermal treatment for thermophysical properties and degradation were performed by using differential scanning calorimetry (DSC) and thermogravimetry analysis (TGA). DSC and TGA results indicated that microcapsules absorbed 203.6 J/g of latent heat and had good thermal stability for textile applications. Meanwhile, microcapsules had thermo-regulation property due to phase changing of the TD solvent, which was a solvent component of TS. Microencapsulation of TS into P(MMAco-MAA) shell was proven by Fourier transform infrared (FTIR) spectroscopy. For thermally stimulated color change determination, UV-visible spectroscopy analysis and photographs taken at 25 C and 50 C were used during temperature increase. Some cotton and wool fabrics imparted microcapsules were prepared by exhaustion technique. The heat absorbance capacities of fabrics during melting were measured as 68.2 J/g for cotton fabric and 72.5 J/g for wool fabric. From T-history measurements, it was resulted that fabrics exhibited cooling and heating effect owing to the released or absorbed latent heat by TD. The color measurements based on CIELab system and photographs of fabrics taken at different temperatures showed that color of fabrics transformed from blue to colorless with increasing temperature. It was seen that the synthesized bifunctional thermochromic and energy storing
