Abstract The effect of using 2% and 10% sodium hydroxide solution as surface treatment of rape straw on its water vapor adsorption properties is analyzed in the relative humidity (RH) range of 0% to 98%. Scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), and Fourier-transform infrared spectroscopy (FTIR) are used to investigate the morphological, chemical and structural changes of the treated straw surface. The mineral particles formed on the surface after the treatment are analyzed using X-ray diffraction (XRD). The application of sodium hydroxide solution results in the disruption of the straw surface. As the concentration More >
