| Abstract: | Direct photothermal conversion of nanofluids as working medium is one of the important parts of solar energy utilization, so
the preparation of nanofluids has attracted the attention of many researchers. Carbon black has the characteristics of chemical stability,
cheap and wide spectrum absorption, and so on. It is widely used in the field of solar absorption and photothermal conversion as a
nanoparticle additive particle. But carbon black is very easy to agglomerate, which affects its application in nanofluids. Carbon black
bone glue nanocomposites were prepared by ball milling with environment-friendly bone glue and carbon black, which improved the
dispersion stability of carbon black in deionized water-based solution. The properties of the sample were characterized by scanning
electron microscope (SEM), UV-visible-near-infrared spectrophotometer (UV-vis-NIR) and self-assembled photothermal conversion
device. The results show that the carbon black bone glue nanofluids solve the problem that carbon black is easy to aggregate, and have
good dispersion stability and photothermal conversion performance. The photothermal conversion efficiency of carbon black bone glue
nanofluids with mass fraction of 0.006% can reach 94%, which is 20% higher than that of deionized water base solution. |
