Conformal single-layer encapsulation of PEDOT at low substrate temperature
In this work, we demonstrate a single-layer encapsulation method for poly(3,4-ethylenedioxythiophene) (PEDOT). This method is achieved by initiated chemical vapor deposition (iCVD) process, which is scalable and employs solvent-free and low-substrate temperature conditions. The encapsulant used, pol...

| Summary: | In this work, we demonstrate a single-layer encapsulation method for poly(3,4-ethylenedioxythiophene) (PEDOT). This method is achieved by initiated chemical vapor deposition (iCVD) process, which is scalable and employs solvent-free and low-substrate temperature conditions. The encapsulant used, poly(divinylbenzene-co-maleic anhydride) (PDVB-MA), was first time synthesized via vapor phase process. This cross-linked iCVD polymer can be rapidly deposited (40 nm min−1) with uniform and conformal morphology. In the test of PEDOT degradation, the encapsulation extended the halflife of PEDOT to 900 h at 30 °C in air, which is more than 10 times of the counterpart without encapsulation. |
