Carbazole-based bi-functional photorefractive polyacrylates were prepared via free radical polymerization and post-azo-coupling reaction. The structure of polymers was characterized by Fourier transform infrared spect...
An aromatic azo-polymer, poly(thiourea-azo-sulfone) (PTAS), has been prepared using 4-(4- aminophenylsulfonyl)benzenamine and diazonium salt solution of 2,6odiaminopyridine. PTAS was easily processable using pol...
A new aromatic azo-polymer, poly(thiourea-azo-naphthyl) (PTAN), has been synthesized using 1-(5- thiocarbamoylaminonaphthyl)thiourea and diazonium salt solution of 2,6-diaminopyridine. PTAN was easily processabl...
Nanomechanical properties of mulfilayer films constructed of polyaniline (PAN/) and azobeneze-containing polyelectrolytes (PNACN and PPAPE) were studied by using nanoindentation method. The multilayer films were p...
