| Summary: | Inkjet printing becomes popular in the electronics industry for its processing time faster than other deposition techniques, and for its lack of requirement of masks and lithography processes. Here, carbon nanotubes (CNTs) and silver are printed on paper substrate, and the behaviour of conductivity of CNTs and the thickness of CNTs based on the number of deposited CNTs layers are studied. CNTs solution used in this project is 12wt% DWCNTs printable solution. Paper substrate is used as the primary substrate for deposition of test structure, and PET substrate is used to find out the thickness of deposited CNTs. The printing conditions are stabilised using Dimatix Material Printer DMP-2800. Computerised control of printing parameters such as jetting speed, firing voltage and drop spacing are achieved using DMP software. After deposition of test structure, annealing, DC characterization, surface dimension measurement and thickness measurement of printed samples are carried out. The results show that the printed sample conditions are achieved as desired. Therefore, it is deducted that inkjet printing technology is possible to produce an printed electronic based on nano material-based printable ink in smooth and stable environment. |
