There are three kinds of packaging included in intelligent packaging. The conductive ink is important in the intelligent packaging. It can be used in the printing antenna of Radio Frequency Identification (RFID) and so on. The PEDT complex with polystyrene sulfuric acid (PEDT: PSS) plays an important commercial role in antistatic and conductive coatings, electronic components and displays. The organic conductive ink was investigated by adding a series of addictive such as DMF (dimethylformamide), DMSO (Dimethyl sulfoxide), and ammonia. And the offset printing performance was tested. The testing result tells us that all DMF and DMSO will improve the conductivity of printed sample on coating paper or PET film in some fraction, especially when the fraction of less than 5% (V/V). By the aging test on the proof, it was found that temperature, moisture and the other environment conditions effect on the proof conductivity too. All above give you a valuable reference in the making and application of conductive ink.
