Studies On Syntheses And Electrostatic Self-assembly Of Polyelectrolytes

The polymers, including emeraldine base, emeraldine salt, homopolyIner and co-polyIners based on boline and anhredlic acid (PANANA) or on whline and 0-theno-benzenesulfonic acidonOABSA), sulfonated polyaniline (SPAN), have been preparedand characterized by FTIR and UV-visib1e techniques. Furthermore, the comParison ofsolubility, stability and ability to cast film has bben pefformed.The polyanions PANANA. SPAN,PAOAB S A have b een su cce ssful l y a ssemb l edwith quartered poly-N,Ndimethyamino ethyl methaCrylate(I'DM on hydrophilicquartz substfatq and we Studed the influence ofpolyelectrolytes concelltfation and ionstrength on adsOrpion amount. In this paPer. two kinds of films, (PANANA/Anodamine B) and mpANA/Rhodamine B mixed with PDop have been assembledand compared. We Observed and compared the appearance of (PANANA/ PDM filmsand Modndne B ndxed wih PDM) films by AFM.The 1ight emitting devicestLEDs) of (PANANMihodamine B mixed with PDM)films has been condru8t6d. and relation of the devices between current and voltage hasbeen investigated. We obserVed the light-emitting phenomenon of LEDs sPin-co8tedwith miwt of MEHPPV and OXD7.
