Hydrochloric Acid → Dopamine

Participants

Reaction Steps

The CNT obtained in Manufacturing Example 2 was added to a solvent mixture of phosphate buffered saline (“PBS”) and acetone mixed in the ratio of 1:1 to have a concentration of 0.5 milligrams per milliliter (mg/ml) and then 1 M of hydrogen chloride (HCl) was used to adjust the acidity of the mixture to a pH of 5.5. Here, 147.5 mg of 1-ethyl-3-(dimethylaminopropyl)carbodiimide hydrochloride and 145.9 mg of dopamine hydrochloride were added to the mixture and mixed for about 4 hours. After completing the mixing, the resulting CNT was separated from the mixture using a 0.2 μm polycarbonate filter and then was dried, thereby obtaining a composite having a yield of 90 percent (%).
