In this study, the silane treated microcrystalline cellulose (SiMCC)/polypropylene composite was prepared. In the first step, the surface modification of microcrystalline cellulose (MCC) with various concentrations of hexadecyltrimethoxysilane was carried-out in order to obtain the SiMCC having good compatibility with PP matrix. Characterizations including SEM, FT-IR, TGA and DSC were employed to analyze the structure of SiMCC. SEM revealed that MCC surface morphology was changed from rod shape into rough particles after silane treatment. In the next step, the obtained SiMCC was mixed with PP powder using twin-screw extruder. Based on TGA results, it was found that the addition of SiMCC led to thermal stability enhancement of PP matrix during melting process. As a result, it was claimed that SiMCC could be an effective heat stabilizer for polymer melt process. Also, the compatibility was achievable, as supported by the gradual degradation of SiMCC observed in TGA thermograms.
