Application of luminescent energy storage phase change fiber

What are phase change fibers?

Over the last 30 years, phase change fibers (PCFs) have been extensively investigated and applied as high-performance nonwoven fabrics and coatings. As a prospective renewable and clean material, PCFs with micro-scale have been successfully prepared by melt/wet spinning for applications in thermal energy storage (TES) and temperature regulation.

What are phase change fibers containing PCMS used for?

The phase change fibers containing PCMs could provide the surroundings relatively constant temperature through absorbing and releasing heat during phase transition process, which is widely used for thermal energy storage , electrical/solar energy harvesting and smart thermoregulatory textiles .

What is a core-sheath phase change fiber (PCF)?

Core-sheath phase change fibers (PCFs) were prepared with polyurethane (PU) as the sheath material and octadecane (OD) as the core materials by coaxial wet spinning. Titanium carbide (Ti 3 C 2), as excellent solar absorber, was added into the sheath layer to achieve efficient photo-to-thermal conversion.

Can micro-scale PCFs be used for thermal energy storage and temperature regulation?

As a prospective renewable and clean material, PCFs with micro-scale have been successfully prepared by melt/wet spinning for applications in thermal energy storage (TES) and temperature regulation. With the development of fiber manufacturing techniques, e.g. electrospinning, ultrafine PCFs have been exploited and investigated in the last decade.

Can pyrene-based aggregation-induced emission luminogen (aiegen) be used as phase change material?

In this study, novel phase change material (PCM) composite fiber films, composed of Py-CH (one novel pyrene-based aggregation-induced emission luminogen (AIEgen))/polyvinyl pyrrolidone (PVP)/polyethylene glycol (PEG), have been produced by electrospinning technology with PEG as the phase change material.

Which fiber has the largest phase change enthalpy?

Sheath-core PU@OD phase change fibers were prepared by coaxial wet spinning, different extruded rate of core layer OD and sheath layer PU was investigated to achieve the largest phase change enthalpy (185.00 J/g).
