Enhancement on amorphous phase in solid biopolymer electrolyte based alginate doped NH4NO3

The present work deals with the development of solid biopolymer electrolyte (SBE) system using a promising biopolymer, namely, alginate doped with various amount of ammonium nitrate (NH4NO3). The SBE system has been successfully prepared via the solution-casting method. The Fourier transform infrare...
