SEM image of SOLBLACK
High optical confinement effect was induced to creekside nanostructures.
Color component was measured by spectrophotometer.
(SE2000)
Blackness:SOLBLACK > PHOSBLACKIII
L*: Blightness (Black 0 - 100 White)
a*: Color(Green - <=> + Red)
b*: Color(Blue - <=> + Yellow)
Optical absorption was calculated from total reflection measuring result.
Heat collecting was observed by water temperature changes in the pipe.
Measurement condition was
Light source:50W
Light distance:10cm
Material of pipe:Aluminum(diag 15mm*L100mm)
Absolute reflectivity was measured by spectrophotometer at 12.
SOLBLACK was showed hegh absorption from visible area to infrared area.
* Grateful to Mr.AKITAYA of Hiroshima univ for providing data.
