Abstract
Multi-walled carbon nanotubes (MWCNTs) have been employed by adding
different functional groups. Nitric acid and sulfuric acid were used at different
rates first to remove the catalyst from the carbon nanotubes and introduce the
carboxylic acid groups on the surfaces of the carbon nanotubes.
These carboxylic groups were used as primers for the use of carbon nanotube
surfaces with thionyl chloride first and then for interaction with aminoprimidine
groups prepared from different chalcones of functional groups
homogenous and heterogeneous rings. The substances were 2-acetylfuran
with aldehydes with the following functional groups (chloride, methyl,
methoxy and hydrogen). Acetyl pyridine was also used with aldehydes with
the following functional groups (chloride, methoxy and hydrogen). Finally,
parafluoracetophenone was used with the following functional groups
(chloride and methyl).
The used chalcones and pyrimidines prepared from chalcones and carbon
nanotubes were characterized by advanced analysis instruments:
X-ray diffraction device - Electronized electron microscopy - Thermal
decomposition - Mass spectrometer - infrared spectroscopy– UV
Spectrophotometer.
Finally, a multi-walled carbon nanotubes (MWCNTs) and multi-walled
carbon nanotubes pyrimidine derivatives have been applied with in the solar
field to determine their efficiency by using the solar simulator.
