Poly(vinyl alcohol)-poly(vinyl pyrrolidone) blends: Preparation and characterization for a prospective medical application
نویسندگان
چکیده
Poly(vinyl alcohol) and poly(vinyl pyrrolidone) were blended and films were obtained by casting method. Glutaraldehyde, hydrochloric acid and lactic acid were added to investigate their effect on mechanical properties, swelling and solubility of the blends with the aim to find a possible material candidate for medium or long term implants. Combination of all three additives (lactic acid, glutaraldehyde and hydrochloric acid) proved as the best choice for poly(vinyl alcohol)/poly(vinyl pyrrolidone) films production with respect to examined properties important for any indwelling medical application. Key-Words: Poly(vinyl alcohol), poly(vinyl pyrrolidone), swelling degree, solubility, crosslink, mechanical properties

Preparation and Characterization of Aligned and Random Nanofibrous Nanocomposite Scaffolds of Poly (Vinyl Alcohol), Poly (e-Caprolactone) and Nanohydroxyapatite
Nanofibrous scaffolds produced by electrospinning have attracted much attention, recently. Aligned and random nanofibrous scaffolds of poly (vinyl alcohol) (PVA), poly (ε-caprolactone) (PCL) and nanohydroxyapatite (nHA) were fabricated by electrospinning method in this study. The composite nanofibrous scaffolds were subjected to detailed analysis. Morphological investigations revealed that the...
متن کاملDesign and study of formulation variables affecting drug loading and its release from Alginate beads
ISSN:0975-1459 The development of alginate beads as a drug carrier system is considered to be more attractive because of its biocompatibility, mucoadhesive property, and its ability to deliver drug particularly in the intestinal pH. The preparation of alginate beads by ionic gelation method avoids the usage of toxic organic solvents and considered to be relatively economical method. However its...
