Resumo: Cellulose from cotton linter was dissolved in NaOH/urea solvent at -13 °C. Then the dissolved cellulose solvent was coagulated in distilled water and two types of sulphate based coagulant which were 5 wt% H2SO4 and 5 wt% (NH4)2SO4 to form regenerated cellulose membrane (RCM). Dried membranes were characterized by using XRD, tensile machine and FTIR. As compared the other two types of sulphate based coagulant, the RCM coagulated in distilled water has the highest tensile and crystallinity but showed the lowest value for the elongation at break. Meanwhile, the RCM coagulated in 5 wt% (NH4)2SO4 has the lowest tensile strength and crystallinity with the highest value of the elongation at break. The RCM coagulated in 5 wt% H2SO4 has intermediate results for all tensile strength, elongation at break and crystallinity compared to those coagulated in distilled water and 5 wt% (NH4)2SO4.
