Application of Wave Effects for Obtaining Composite Materials Based on Starch and Polyvinyl Alcohol
- 2 Downloads
An alternative method for obtaining liquid-phase composite materials based on starch and polyvinyl alcohol is proposed with exerting wave resonance effects on a mixture of polymeric solutions. It has been established that the use of wave treatment makes it possible to obtain a twofold increase in the stability of starch/polyvinyl alcohol composites in time as compared to samples obtained using a traditional blade agitator. By using IR spectrophotometry, it is shown that an increase in the amount of intermolecular hydrogen bonds occurs in the starch/polyvinyl alcohol system as a result of wave processing. The use of wave technology provides a higher surface homogeneity of film materials formed from liquid-phase starch/polyvinyl alcohol composites.
