, electricity and chemical property.Goed deep into its wide application prospect also not with carbon nanotube and nano materials research in recent years
It shows disconnectedly.Carbon atom is in carbon nanotube with sp2Based on hydridization, while there are a degree of for hexangle type network
Bending forms Space expanding, wherein certain sp can be formed3Hybrid bond, that is, the chemical bond formed while having sp2With
sp3Mixed hybridization state, and these p tracks overlap each other and form the delocalized big pi bond of height outside carbon nanotubes lamella,
The big pi bond of carbon nanotube outer surface is carbon nanotube and some changes for having the macromolecular for being conjugated performance compound with non-covalent bond
Learn basis.Carbon nanotube shows following numerous advantage as a kind of novel electrode material for super capacitor, carbon nanotube:
The specific surface area of superelevation, good electric conductivity, excellent stable chemical property and wide potential window.But many feelings
Under condition carbon nanotube be all multiple-layer stacked together, area between layers is not utilized effectively, actual capacity ratio
Only wall carbon nano tube capacity is low.How to realize that effective dispersion of carbon nanotube is to improve and improve carbon nanotube chemical property
Important channel.In addition, carbon nanotube is overlapping with the compound also inhibition carbon nanotubes lamella of other nanostructures.By high capacity
Transition metal nitride or conducting polymer and carbon nanotube to carry out lamination compound, one side carbon nanotube by other substances every
Leave, reunion can be reduced, increase the mobility of electrolyte, on the other hand, carbon nanotube be it is compound after fake capacitance substance mention
Be supplied with electric power the three-dimensional network of sub- conduction.Composite material exhibits based on carbon nanotube go out synergistic effect, are obtaining the same of high capacity
When maintain good high rate performance.
Carbon paste electrode is the Carbon Materials using electric conductivity, if the adhesive of graphite powder and hydrophobicity is mixed and made into paste,
Then it is coated in the surface of electrode bar or is packed into electrode tube and manufactured a kind of electrode.Since carbon paste electrode is nontoxic, electric
The advantages that chemical window is wide, preparation method is simple, at low cost, surface easily updates, aftercurrent is small, is widely used to electrochemistry
In analysis, biosensor preparation and environment measuring, food and medicine analysis.But there is also some disadvantages for carbon paste electrode, such as conductive
Performance is poor, and sensitivity is low, stability difference etc..In order to improve the performance of carbon paste electrode, using titanium nitride/carbon nanotube composite
Expect the conductive material as carbon paste electrode, improves electrode sensitivity and selectivity.
Paracetamol is most common non-anti-inflammatory analgesic-antipyretic, and refrigeration function is similar to aspirin, analgesic activity compared with
It is weak, it is kind best in acetophenone amine drug without anti-inflammatory anti rheumatism action.Particularly suitable for carboxylic acids drug cannot be applied
Patient.For the diseases such as catch a cold, have a toothache., suitable for fever caused by flu or alleviate the symptoms such as mild to moderate pain, for a long time
A large amount of medications will lead to hepatic and renal function exception.The method for having reported measurement paracetamol has spectrophotometry, high performance liquid chromatography
Method, capillary electrophoresis, titration and electrochemical method etc..It is that one kind is accurate using carbon paste electrode method measurement paracetamol,
Sensitive and effectively analysis method.
