Abstract
There has been growing interest in nanosize and interface effects on fast ionic transfer. Several types of multilayered electrolyte have been demonstrated thus far. Ultra-thin layers of oppositely charged poly(allylamine hydrochloride) (PAH) and Nafion® were alternately deposited on a negative-charged glass substrate via layer-by-layer assembly technique. Thickness of a Nafion layer increased from approximately 5 to 15 nm with increasing the pH of the PAH solution. Proton conductivity of PAH/Nafion multilayers strongly depended on the thickness of a Nafion layer.
