Özet
Personal thermal management by controlling
radiation energies of body and sun can be used in all environments and
contributes to sustainability components with the advantages of energy saving, low
chemical usage and comfort enhancements under dynamic conditions. In this
study, passive radiative heating nanocomposite films were produced by using
sodium alginate as matrix and zinc oxide (ZnO) and aluminium oxide (Al2O3)
nanoparticles as nanofiller having far infrared radiation reflecting, hence
passive heating functions. Nanocomposite films including 20% sodium alginate
powder, deionized water, 20% of ZnO and Al2O3
nanoparticles and surfactant was stirred by magnetic and ultrasonic stirrers in
turn. Films produced within petri dishes after drying at room temperature were
analysed by FT-IR and SEM for chemical structure and morphological analysis,
respectively. Emissivity ratios giving idea about the heating performances of
the films were determined with IR camera (Fluke Ti100 Thermal Imager), heated
plate, and data logger system. Also, heating performance was measured by a test
system including far infrared lamp, thermal camera and temperature sensors. Results
show that emissivity of the films increased by around 18% with the selected
nanoparticles. The heating performance obtained in the nanocomposite film form
may not only be used for the products where heating is necessary such as
surgical gowns, knitted/woven clothing, but also for cosmetic/medical
applications (beauty masks, wound dress, etc.) enabling skin care/healing.
