The main objective of this report is the preparation and characterization of cellulose biofilm from coastal pandanus (Pandanus odorifer) leaves. The first experiment parts is the preparation of coastal pandanus leaves biofilm using a simple dissolution method followed by casting evaporation technique. Further experiments are the characterization of the produced biofilm using Scanning Electron Microscopy (SEM) in order to investigate the morphology of biofilms of pandanus leaves and Energy Dispersive X-ray (EDX) analysis to detemine their main composition. In addition, Fourier Transform Infra-Red (FT-IR) spectroscopy analysis was carried out to compare the main functional groups in the coastal pandanus leaves against to the corresponding biofilm. The SEM analysis shows that, the coastal pandanus cellulose biofilm has almost homogenous morphology. The EDX analysis shows te main elements in the corresponding films were carbon and oxygen (48.19% mass and 38.42% mass, respectively). Based on the FTIR observation, the use of TFA as solvent has impact to functional groups stability of the raw material.
