A dynamic passive thermoregulation fabric using metallic microparticles

Abstract: Maintaining comfort using photonic thermal management textiles has a large potential to decrease the energy cost for heating and cooling in residential and office buildings. We propose a thermoregulating fabric...

“…The light green line represents the calculated set point temperature for emissivity in the range of zero (perfect reflector, 11 °C) to one (blackbody emitter, 26 °C). With the lowest set point of 16 °C, the warming functionality of the design performs better than the Omni-Heat technology (20.6 °C), MMDF (metal microparticle-based fabric, 18 °C), and cotton (22.8 °C). The warming functionality is negatively affected because the upper set point temperature is below the thermal comfort range.…”

“…The major drawbacks of the above-mentioned technologies are that some designs require an external input to activate the dynamic functionality, such as an applied voltage or mechanical pressure, resulting in energy consumption . Other designs require humidity as a trigger for a dynamic switch; therefore, the user has to sweat for actuation, causing discomfort. , In previous works, we demonstrated a static emissivity-modulating textile based on a Janus-yarn design and dynamic transmittance-modulating designs based on metal wires as well as metallic and dielectric particles . A few other surface-emissivity-based radiative cooling technologies were proposed using various photonic platforms (see the following reviews). , …”

“…[7][8][9] Recently, passive cooling materials relying on highly solar reflective and thermally emissive radiation to achieve "green cooling" have attracted more attention. [10][11][12][13] On the one hand, significant progress in polymer-based coating cooling materials has been achieved, including hierarchically porous polymer coatings and scalable cooling coatings. 14,15 On the other hand, several novel cooling materials have also been reported, [16][17][18][19][20] such as nano-micro-structured plastics, 21 nanofiber membranes, 22 gradient epsilon-near-zero materials, 23 etc.…”

“…5 Nowadays, great interest arises to develop passive warm-keeping textiles that enable to reduce carbon emissions by turning down indoor heating in winter. 6,7 Polar bear hair's structure becomes one of the focuses concerned by researchers who explore warm-keeping textiles with functional advantages. 8,9 The hollow porous structure of polar bear hair endows it with unique optical property and allows a large quantity of still air inside, which could effectively reduce heat loss and block the low temperature in polar region.…”
