压电波形对喷墨打印电极的调控规律
Regulation Rules of Piezoelectric Waveform on Ink-jet Printing Electrode
摘要
Abstract
Piezoelectric printing is one of the main processes of printed electronics.In this process,piezoelectric waveform has a direct impact on the spray regime of ink droplets,which will play an important role in the devices printing.In this text,effect of piezoelectric waveform on printing thin film transistor (TFT) electrode was studied.By changing slew rate and duration,the piezoelectric waveform parameters,a series of printing samples were obtained,and their patterning quality and surface roughness were measured.With the increasing of the slew rate and duration,the kinetic energy of the ink droplet increases,the pattenting quality improves first and then deteriorates,and the surface roughness of final printing pattern gets higher.TFT electrodes with fine pattern are fabricated when the slew rate is from 0.08 V/μs to 1.65 V/μs,and the duration is from 1.216 μs to 2.688 μs.Fine-patterned TFT electrodes with surface roughness of 59.04 nm and 59.27 nm are fabricated when the slew rate and duration are 0.25 V/μs,2.688 μs and 0.65 V/μs,1.600 μs,respectively.By adjusting the parameters of piezoelectric waveform,the optimization of printing quality can be achieved.关键词
