effect of plasticizers (water and glycerol)

Effect of glycerol plasticizer loading on the physical

Abstract. Translational diffusion of a fluorescein probe has been measured in iota-carrageenan edible films containing different amounts of glycerol (0, 15, 30, and 45%), using fluorescence recovery after photobleaching (FRAP) experiments. The effects of this plasticizer as well as the plasticizing effect of water on the diffusion of

Jan 1, 2018 · Glycerol was added as plasticizer to increase the flexibility. Observation was carried out on tensile strength and elongation of bioplastic with a variation of 15, 20, 25, and 30 wt% of...

Glycerol as an efficient plasticizer to increase the DC

Although a wide variety of bio-based plastics are under development, this review focuses on plasticizers utilized for the most extensively studied bioplastics including poly (lactic acid), polyhydroxyalkanoates, thermoplastic starch, proteinaceous plastics and cellulose acetates.

Water and Glycerol as Plasticizers Affect Mechanical and

At lower a w (0.11) and low plasticizer concentration, the sorbitol plasticized film showed highest water sorption while glycerol plasticized film showed highest sorption at higher a w. Glycerol being smaller in size penetrated better into the polymer increasing available – OH to interact with water (Donhowe and Fennema 1993). In comparison

The Effect of Plasticizers on the Properties of Polyvinyl

Glycerol has the biggest effect on the water content of films at the stationary state of the permeation process, which induced greater plasticization and thus favors the moisture transfer [62,63]. Farahnaky et al. reported that the WVP of wheat starch films without a plasticizer was higher than that of films containing 20% or 30% glycerol. This
