This study investigates the fabrication of a composite film composed of polyvinyl alcohol (PVA) and glycerol. incorporating nanosilica derived from municipal solid waste incinerator bottom ash (BA). The nanosilica is blended with a PVA film-forming solution containing glycerol as a plasticizer. The composite films are characterized using Fourier transform infrared spectroscopy (FTIR). https://www.animationbengal.com/?w=deal-time-the-best-of-shirley-temple-vol-ii-online-now-super-choice
