Özet
Purpose – Personal thermal management by controlling the radiation energies of both the body and the 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 using sodium alginate as the matrix and zinc oxide (ZnO)
and aluminum oxide (Al2O3) nanoparticles as nanofillers having far infrared radiation reflecting, hence passive
heating functions.
Design/methodology/approach – Nanocomposite film solutions were prepared by stirring sodium alginate
powder, deionized water, ZnO and Al2O3 nanoparticles (20% wt of matrix polymer) with surfactant using
magnetic and ultrasonic stirrers in turn. Films produced within Petri dishes after drying at room temperature
were analyzed by FT-IR, UV-VIS-NIR spectroscopy and SEM for chemical, radiation management and
morphological characteristics, respectively. Emissivity values giving idea about the heating performances of
the films were determined with an IR camera and a hotplate system. Moreover, direct heating performances
were measured by the hotplate system including a far-infrared lamp.
Findings – Results showed that the emissivity of the films increased by approximately 18% and 16% with
ZnO and Al2O3 nanoparticles, respectively. Moreover, NaAlg–Al2O3 nanocomposite film exhibited passive
radiative heating performance of 3.58 8C, higher than the heating performance of NaAlg–ZnO nanocomposite
film which is 2.97 8C when compared to the reference NaAlg film. These results indicate that both NaAlg–ZnO
and especially NaAlg–Al2O3 nanocomposite films have excellent far-infrared emission and absorption
properties ensuring a significant heating effect.
Originality/value – In addition to other clothing types, the heating performance obtained with the produced
nanocomposite structures may be applied to different types of cosmetic/medical applications (beauty mask,
wound dresses, etc.) enabling skincare/healing with the advantage of the sodium alginate matrix.
