Influence of the Microwave and Ultrasonic Synergistic Effect on Properties of Methylcellulose/Stearic Acids Films

Abstract:

The Influence of the microwave (MW) and ultrasonic (US) synergistic effect on mechanical and water vapor barrier properties of methylcellulose (MC)/stearic acids (SA) films was studied. For this purpose, the initial emulsions were prepared and treated in a MW and US combination reaction system. The water vapor permeability (WVP) of the films was determined, as well as the mechanical properties. As a result of the extending of MW and US treatment time, the WVP of MC/SA films declined significantly. And the tensile strength (TS) and elongation percentage at break (E) were also affected by the treatment greatly. When the treated time was 20 min, the highest TS and E were observed.
