BACKGROUND Chitosan, an important biodegradable and biocompatible polymer, has demonstrated wound-healing and antimicrobial properties. OBJECTIVES This study aimed to evaluate the antimicrobial properties of mafenide acetate-loaded nanofibrous films, prepared by the electrospinning technique, using chitosan and polyvinyl alcohol (PVA). MATERIALS AND METHODS A 3(2) full factorial design was ...

A dual functional and water soluble spin-coatable lanthanum strontium manganese oxide (LSMO) resist has been developed that consists of lanthanum nitrate, strontium nitrate, manganese nitrate, polyvinyl alcohol and water. Energetic nitrates plus polyvinyl alcohol fuel promote autoignition and produce nanopatterns (<60 nm) upon mild electron beam exposure (<2 mC cm−2). The formation of cubic per...

Keratin solution was separately blended with collagen, gelatin, sericin and starch for films preparation. All the blended films had smooth surfaces without phase separation, except the keratin/ starch blend film. The native keratin film showed small particles embedded in all the film surfaces that resulted in them being rough. The structure of the native keratin film changed from beta-sheet to ...

In this study, research will be carried out to identify the functional group behavior of glassy and rubbery polymeric blend membrane with amines. Polymeric blend membranes with different blending ratios were prepared and the developed membranes were characterized by FTIR to see the effect of blend ratio on different functional groups. The developed membranes are flat dense sheet membrane of 20%...

In the manufacture of ophthalmic medicinal films, special attention should be paid to choice a film-forming substance, since both shape future film and its properties as whole depend on it. This article provides laboratory analysis with comparative assessment optimal concentrations two substances, polyvinyl alcohol gelatin. Most presented formers have number disadvantages, such thickness, insuf...

Pollution and destruction of the environment due to accumulation non-degradable plastics are some most important concerns in world. A significant amount this waste is related polymers used food packaging. Therefore, experts industry have been looking for suitable biodegradable alternatives synthetic polymers. Preparing biocompatible films based on starch a good choice. In study, various factors...

Inoculation of the bacterial cells of microbial seed coating agents (SCAs) into the environment may result in limited survival and colonization. Therefore, the application efficacy of an encapsulated microbial seed coating agent (ESCA) was investigated on potted cotton plants; the agent was prepared with polyvinyl alcohol, sodium dodecyl sulfate, bentonite, and microencapsulated Bacillus subtil...

Antioxidant (quercetin) and hypoglycemic (voglibose) drug-loaded poly-D,L-lactideco-glycolide nanoparticles were successfully synthesized using the solvent evaporation method. The dual drug-loaded nanoparticles were incorporated into a scaffold film using a solvent casting method, creating a controlled transdermal drug-delivery system. Key features of the film formulation were achieved utilizin...

The film forming ability of chitin (CT) blended with polyvinyl alcohol (PVA) were prepared a seriesof nine different ratios CT:PVA, (10:90, 20:80, 30:70, 40:60, 50:50, 60:40, 70:30, 80:20, 90:10v/v),using 2% solution and 10% solution. All films have highlytransparent, smooth surface pale-yellow color. characterized by usingthe physical parameters, the physico-mechanical properties, degree swell...
