Contexte de travail
IEMN (UMR 8520) has expertise in the field of microfabrication technologies in particular on polymers. The institute has clean room facilities to structure these materials at the micrometer scale and to characterize their physico-chemical properties. This expertise is provided by the BioMEMS group. Thanks to its expertise on physics of waves and interfaces, particularly in the electromagnetic fields, the EPHONI team brings its skills on photonic crystals and on thermal model numerical study and model development.
The POCOMA project aims at developing passive polymer membrane for clothing in order to improve the thermal comfort felt by a person at rest through the control of Mid-InfraRed (Mid-IR) radiation.
Indeed, at rest, 50% of the heat loss of the human body is due to radiative loss in the Mid-IR range (5-11µm). We propose to control the temperature of the space located between the human skin and the textile, called microclimate (MC), by introducing a polymer membrane structured at the microscale to modulate the textile/Mid-IR interaction (transmission, reflexion and absorption in the 5-11µm range) and so the thermal behaviour at the macroscale.
Two strategies will be developed, optimized and associated with each other: the fabrication of particle-charged membranes and photonic microstructured membranes. Quantitatively, our objective is thus to develop a solution to reduce the T° of a room by several degrees while ensuring a constant skin T° compatible with a feeling of comfort.
