Abstract :

A new method for preparation of starch/cellulose composite is reported. The composite was obtained by mixing both mercerized cellulose and corn starch. Different techniques have been utilized for characterization of starch/cellulose composite such as FT-IR, X-ray diffractometer and differential scan colorimetric. FT-IR showed a C-O bond stretching band at 9.00 m-1 for starch/cellulose composite (1:1) sharper than those in both cellulose and starch, indicating that there is interaction between the amorphous starch and cellulose. Moreover, X-ray diffractometer showed a strong interaction between both mercerized cellulose and starch at 80?C due to a possible enhancement in the close packing of the starch molecules. However, starch/cellulose composite at a ratio of 2:1 exhibited the smallest value of ΔCp compared to those of different ratios. This finding indicates that starch/cellulose prepared in a ratio of 2:1 has the lowest thermal expansion and the highest thermal stability.
