thermal stability and water absorption of the NS, CNS and blended starch foams were determined.
The ratio of the two starch components had a significant influence on the density and thickness of
the blended starch foams. All blended starch foams showed good water resistance. Moreover, the morphology
of the blended starch foam with the NS/CNS ratio of 50/50 showed a more ordered distribution
of cell sizes with thicker cell walls than for the NS and CNS foams. The thermal stability of the blended
starch foams was somewhat lower than the stability of the NS foam but not to the extent that it affected
any potential practical applications.
