FTIR analyses were conducted to identify the chemical bonds formed within the synthesized membrane structure and to assess its structural properties. FTIR analyses were carried out using a Bruker Vertex FTIR spectrophotometer in the wavenumber range of 400–4000 cm-1. These analyses utilized an ATR m...
