Sorption of
water vapor by gelatin-based polymers: estimation of rate and sorption degree
using spin probe method
Abstract
Spin-probe
method is applied for the estimation of rate and sorption degree of water vapor
by gelatin-based polymers. The rate and the sorption degree of gelatins are
shown to be influenced by their cross-linking extent. The time of cross-linked
gelatin swelling in water vapor at 300 K is three times higher than the time of
native gelatin swelling in the same conditions.
Key words: electron paramagnetic resonance, gelatin,
spin-probe method, sorption.
