    • Carbon Nanotube Spectrally Selective Solar Absorbers 

      Chen, Zhonghua; Nguyen, Quang Hong; Boström, Tobias (Journal article; Tidsskriftartikkel; Peer reviewed, 2015)
      The use of multi-walled carbon nanotubes (MWCNTs) as spectrally selective solar thermal absorbers (SSA) in solar thermal collectors is presented in this paper. CNT layers were coated by electrophoretic deposition (EPD) on aluminum substrates. Stable aqueous CNT suspensions consisted of multi-walled CNTs, DI water and surfactant was used for EPD. The deposited samples were heat treated in a tube ...

    • Carbon Nanotube Spectrally Selective Solar Thermal Absorbers 

      Chen, Zhonghua (Doctoral thesis; Doktorgradsavhandling, 2016-10-04)
      The main objectives of this work were to investigate a) the feasibility of depositing multi-walled carbon nanotubes (MWCNTs) homogeneously on metal substrates by electrophoresis and b) the performance of MWCNT coatings as spectrally selective absorbers. Stable aqueous MWCNT suspensions were prepared and employed in electrophoretic deposition (EPD) of MWCNT coatings on aluminum substrates. The surface ...

    • Electrophoretically deposited carbon nanotube spectrally selective solar absorbers 

      Chen, Zhonghua; Boström, Tobias (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-11-11)
      Three types of carbon nanotubes(CNT) have been investigated regarding their suitability as spectrally selective solar thermal absorbers.The CNT coatings were electrophoretically deposited on aluminum substrates using kinetically stable CNT aqueous suspensions, of which two CNT aqueous suspensions (N-CNT and P-CNT suspensions) were prepared as part of this study and the third one (T-CNT suspension) ...
