Synthesis and Characterization of Soy Protein Isolate/MMT Nanocomposite Film for the Control Release of the Drug Ofloxacin

Abstract

Nanocomposites were prepared by blending soy protein isolate with different percentage of MMT by melt extrusion technique. The nanocomposites were characterized by using, XRD, TEM, SEM and TGA methods. The XRD studies indicated the absence of diffraction peaks for the bio-nanocomposites. From the TEM studies it was ascertained that the degree of exfoliation increased with increase in MMT content. The morphology of the nanocomposites was ascertained from the SEM studies. The degradation pattern of the nano-composites was evaluated from the TG analysis. The drug delivery system of the nanocmposites was investigated by blending the nanocomposites with ofloxacin at different pH media. The various kinetic parameters were evaluated and the mechanism of drug delivery has been postulated based on the kinetic data

Simultaneous plasticization and blending of isolate soy protein with poly[(butylene succinate)‐co‐adipate] by one‐step extrusion process

“…In the case of PISP, the first weight loss in the range 150–350 °C corresponds to the plasticizer evaporation and the degradation of proteins bonded with glycerol. The final mass loss observed from 650 °C corresponds to the partial oxidation of carbonaceous residues from PISP [Figure (a,b)] Concerning the PBSA/PISP blends, the weight loss in the range 150–350 °C is ascribed to the glycerol evaporation and the decomposition of protein bonded with glycerol, the final weight loss beyond 350 °C is due to the degradation of PBSA molecules. The final mass loss observed from 650 °C corresponds to the partial oxidation of carbonaceous residues from PISP.…”

Thermal stability and flammability of environmentally friendly polymer nanocomposites using biodegradable polymer matrices and clay/carbon nanotube (CNT) reinforcements

“…Recently, a number of researchers also reported the improved thermal stability of various protein nanocomposites. 43,44 Various researchers have studied the thermal stability of poly(butylene succinate) (PBS)/clay and poly[(butylene succinate)-co-adipate] (PBSA)/clay nanocomposites through TG. [45][46][47][48][49][50][51][52] The weight loss due to the formation of volatile products after degradation at high temperatures, either in inert gas atmosphere or air, is usually monitored as a function of temperature.…”

Enhancement in Mechanical Properties of Polystyrene Filled with Carbon Nano-Particulates (CNP<sub>S</sub>)

“…It is proposed that with decreasing filler dimension or increasing filler content a significant improvement on contact area between the filler and matrix was carried out, and in turn this would greatly and effectively improve the transfer of the load between the fillers and the polymer matrix [8]. The inorganic nano-fillers, ranging from 1 to 50 nm, were successfully incorporated into the polymeric matrix to strengthen and improve the ductile polymer to be more stiff and resistant for abrasion [9,10].…”

“…Glass fibers are added to polymeric materials to increase the specific strength and since both are relatively inert materials, allows for application in corrosive environments [8,9].…”
