The poly(3,4-ethylenedioxythiophene):poly(4-styrenesulfonate) (PEDOT:PSS) film is a promising material for electrodes, biomolecular sensor channels, and probes for physiological signals because the electrical conduction of PEDOT:PSS is tuned simply through the electrochemical reaction with the target analyte. However, forming a specific morphology or nanostructure on PEDOT:PSS thin films immerse..

Recently published paper in ACS Langmuir has been selected as the supplementary cover image. And this paper was highlighted in lots of korean newspapers due to the outstanding enhancement of the electrical stability of PEDOT:PSS film in the high moisture ambient. Thanks to Inwoo. He really showed the enthusiasm and the passion to solve the problem in front of him. All the victory belongs to him ..

Sejung Park (박세정, 18학번, 전남대) came back our laboratory as a master degree student. She started studying the interesting composite materials which consists of carbon nanotubes (CNTs) and cellulose nanofibers (CNFs). Especially, she is working on the efficient current collector based on CNF-CNT composites for all solid-state batteries. Lots of advanced researches will be expected by her passionate ..

In this study, we present the fabrication of a poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS)-based resistive random access memory (RRAM) device using a fully vacuum-free and solution-processed fabrication method, realized using a printable top electrode. Three different printable electrodes, namely Ag epoxy, ethylene glycol(EG)-treated PEDOT:PSS, and dimethyl sulfoxide(DMSO..

This study investigates a hybrid lamination electrode based on a silver nanowire and a conductive polymer for the top electrode of bi-directional polymer light-emitting diodes (PLEDs). Through a vacuum-free hot-press lamination step, the proposed hybrid electrode employed a complete and concrete electrical contact with the underlying emissive polymer layer. In addition, by inserting a hole injec..

Yejin Kim (김예진, 18학번, 전남대) has joined our research group as a master degree student. She has been studying the fully vacuum-free fabrication of polymer light-emitting diodes by utilizing hybrid lamination electrodes. She will become an expert in the field of electroluminescence device based on emerging materials like quantum dots and perovskites. as well.

Fully vacuum-free manufacturing could be achieved from a silver nanowire and conductive polymer-based transparent lamination top electrode, thereby achieving complete and concrete electrical contact with the underlying polymer bulk-heterojunction layer through a simple hot-press lamination step. In addition, for the insertion of an appropriate hole-extracting interlayer between the lamination el..

Using “fully vacuum-free” and “solution-process” fabrication This research has been conducted by UROP (Undergraduate Research Opportunities Program) in JNU and Capstone Design class in 2021. This is the first step. And we are going to achieve highly effieicnt OLEDs with great cost-effectiveness within this year !!
