PhD position: Organic Plastic Crystals: addressing the next generation of TES systems based on solid-solid PCMs

Research Field: Chemistry 
Sub Research Field:  

Job Summary

Solid-solid phase change materials (PCMs), particularly organic plastic crystals (OPCs), hold great potential for next-gen thermal storage systems. They combine the simplicity and cost of traditional solid materials with the high energy density of PCMs. OPCs, with transitions from 40°C to 200°C, suit both building and industrial applications. Nevertheless, further exploration of these materials and their enhancement is necessary to fully unlock their potential and penetrate the energy storage market.

Job Description

The main goal of this PhD thesis is to develop and optimize solid-solid PCMs based on OPCs, aiming to attain superior thermal properties while gaining insights into their underlying mechanisms and assessing their techno-economic feasibility.

Key tasks for doctoral candidate:

• Synthesis of coatings with different natures (polymeric, ceramic, hybrid, etc.).
• Synthesis and processing of solid-solid PCMs, including their doping with functionalized particles and their combination with other solid-liquid PCMs.
• Deep materials characterization by, for example, Hot Disk, Differential Scanning Calorimetry (DSC), Thermogravimetric Analysis (TGA), dilatometer, Helium pycnometer, Dynamic Mechanical Analysis (DMA), Scanning Electron Microscopy (SEM), dilatometry, particle size distribution, XRD, surface area BE, mechanical testing, etc.
• Assessment of the techno-economic feasibility of scaling up and manufacturing processes for the material, as well as evaluating its impact on a Thermal Energy Storage (TES) system.

Area: Thermal energy storage (TES)
Research group: Phase Transitions and Critical Behaviors
