Polyvinyl alcohol (PVA) nanocomposite films with sorghum starch nanocrystals (SSN) were prepared by incorporating various concentrations of SSN in PVA. SSN was isolated using acid hydrolysis of sorghum starch. The morphological studies of SSN using atomic force microscopy (AFM) revealed that the particle size varied from 65 nm to 68 nm. The mechanical properties of PVA-SSN nanocomposite films i...

Graphene oxide (GO)/polyvinyl butyral (PVB) nanofibers were prepared by a simple electrospinning technique with PVB as matrix and GO as a functional nanomaterial. GO/PVB nanofibers on glassy carbon electrode (GCE) were reduced through electrochemical method to form reduced graphene oxide (RGO)/PVB nanofibers. The morphology and structure of GO/PVB nanofiber were studied by scanning election mic...

A detailed study was performed to investigate the dosimetric characteristics of polyvinyl butyral (PVB) containing 10,12-pentacosadiynoic acid (PCDA) monomer. PCDA monomer undergoes radiation polymerization when subjected to gamma rays inducing change in the absorption spectra in the UV region of the spectrum. Unirradiated film is colourless and has four absorption peaks at 216 nm, 227nm, 241nm...

Short cellulose nanofibrils (SCNF) were investigated as a reinforcement for polyvinyl alcohol (PVA) fibers. SCNF fibers were mechanically isolated from hard wood pulp after enzymatic pretreatment. Various levels of SCNF were added to PVA and gel-spun into continuous fibers. The molecular orientation of PVA was affected by a combination of wet drawing during gel spinning and post-hot-drawing at ...
