The FTIR method is employed to investigate the chemical reaction between cellulose fiber and MAH coupling agent. The typical FTIR spectra of MAH treated and untreated EFB fibres are depicted in Figure . The presence of -OH groups is indicated by the broad peaks observed in the range of 3600-3070 cm -1 across all spectra. Additionally, The C-H stretching is responsible for the peak at 2946 cm -1 . The absorption peaks at 1740 cm -1 and 1622 cm
