Preparation, performances and applications of multi-functional photoluminescence form-stable phase change materials

Bi-Functional Paraffin@Polyaniline/TiO2/PCN-222(Fe) Microcapsules for Solar Thermal Energy Storage and CO2 Photoreduction

“…Among the various prepared MEPCMs microcapsules, the multi-functional MEPCMs have aroused an increasing research interest [ 18 , 19 ]. The multi-functionality of MEPCMs can be achieved in the following three ways: (1) embedding nanoparticles (NPs) into the shell, (2) utilizing function-specific shell materials, and (3) designing the shape of the microcapsule [ 18 ].…”

Typically, one way was employed to prepare the multi-functional MEPCMs, for instance, the functional NPs ferric oxide (Fe 2 O 3 ), titanium dioxide (TiO 2 ), zinc oxide (ZnO), metal–organic frameworks (MOFs), and were embedded into the polymeric shell, or the functional inorganic shells like TiO 2 , cuprous oxide (Cu 2 O), tin dioxide (SnO 2 ), and cadmium sulfide (CdS) were directly used for the shell to achieve the UV shielding, fluorescent, photothermal conversion, photocatalysis, antibacterial, and thermal conduction, etc.…”

Homogeneous‐to‐Heterogeneous‐Strategy Enables Multifunctional Phase‐Change Materials for Energy Storage

“…[7] However, most reported PCMs only have a single function of TES, which is difficult to meet the increasing application requirements. Indeed, some PCMs with multifunctional properties have also emerged, such as, Zhang et al [8] utilized a two-step method of thiol-functionalized silica interfacial polycondensation and then sliver reduction to synthesize a microcapsule PCMs of silver/ silica double-layer shell encapsulating n-eicosane core, which not only possess high latent heat for thermal energy storage conventionally, but also equip high electrical conductivity in the presence of sliver shell and antimicrobial effectiveness; Yu et al [9] used PMmPVPC18, a type of photoluminescence side chain liquid crystalline polymers, as the gelator and container of paraffin wax (PW) to prepare a novel multifunctional PCMs with both high latent heat-storage and high fluorescence quantum yield; Chen et al [10] fabricated a type of metal-organic frameworks (MOFs) based PCMs which use MOFs as the host supporting materials to load the guests of carbon quantum dot molecules for high-intensity fluorescence function and stearic acid for an excellent thermal energy storage. All the above representative research has achieved functional integration originated from various components during the PCMs preparation process.…”

“…More than this, the gelator of photoluminescence multifunctional PCMs was polymerized by more than ten monomers. [9] And all of these PCMs are only applicable to possess some specific functions. The MOFs based PCMs provided a universal strategy which can be applied to other MOF hosts, but the process of forming MOFs is condition-harsh and sophisticated which lifts the difficulty to materials preparation.…”
