Zusammenfassung:Urchin-like Cs x WO 3 particles were synthesized using bacterial cellulose (BC) as a template by the hydrothermal method. The effects of the BC addition amount on the morphology, W 5+ content and transparent thermal insulation of Cs x WO 3 were studied. It has been confirmed that abnormal growth of Cs x WO 3 rods was greatly reduced after introduction of BC into the precursor solution. Moreover, introduction of BC into the precursor solution could significantly improve the transparent thermal insulation properties of the Cs x WO 3 film. In particular, when the BC amount was appropriate, the prepared Cs x WO 3 film exhibited better visible transparency, with the visible light transmittance ( T Vis ) more than 60%. In addition, the urchin-like particles could be transformed into small size nanorods after H 2 heat-treatment, exhibiting excellent visible light transparency and thermal insulation performance. In particular, it has been proved that the 20BC-HT-Cs x WO 3 film exhibits excellent thermal insulation performance, and shows broad application prospects in the field of solar heat filters and energy-saving window glass. Urchin-like Cs x WO 3 particles were synthesized using bacterial cellulose (BC) as a template by the hydrothermal method. The BC could greatly reduce the abnormal growth of Cs x WO 3 rods and improve the transparent heat-insulation properties of Cs x WO 3 film.
