	%X Cross-linked konjac glucomannan and kappa
carrageenan film were prepared by chemical crosslinking using
glutaraldehyde (GA) as the crosslinking agent. The effect
crosslinking on the swelling degree was investigated. Konjac
glucomannan and its mixture with kappa carrageenan film was
immersed in GA solution and then thermally cured. The obtained
cross-linked film was washed and soaked in the ethanol to remove
the unreacted GA. The obtained film was air dried at room
temperature to a constant weight. The infrared spectra and the value
of swelling degree of obtained crosslinked film showed that
glucomannan and kappa carrageenan was able to be cross-linked
using glutaraldehyde by film immersion and curing method without
catalyst. The cross-linked films were found to be pH sensitive,
indicating a potential to be used in drug delivery polymer system.
