starch/cellulose composite in different ratios has been reported. The composite
is obtained by mixing cellulose extracted from paper garbage and corn starch in
PEG/NaOH solution. Starch/cellulose composite is characterized by different techniques,
namely XRD, TGA and optical absorption measurements. From XRD data, it is
observed that cellulose would lead to expand the d-spacing of (10
plane and decrease the d-spacing of (110) plane of starch. The UV absorption
peaks are shifted towards the longest wavelengths in the visible region for
starch/cellulose composite. However, the refractive index value decreases from
1.44 to 1.08 and consequently the dielectric constant value decreases from 2.07
to 1.16 with increasing the starch ratio. Furthermore, the glass transition
temperature increases from 107 °C for starch to 115 °C for
starch/cellulose composite. However, the excess in starch ratio leads to
increase in local crosslink density in the composite network.
