This study presents an easily prepared film based on alkaline starch-polyvinyl alcohol hybrid and lignin fiber as additive (SPL film). The SPL was under acidic conditions through a polycondensation reaction of PVA mixture incorporating starch from agriculture or forest source. examination using scanning electron microscopy (SEM) showed that the surface smooth had good compatibility within hybri...

objective: intravascular catheter-associated infection has been increasing hospitalization in post-surgery patients mainly due to microbial colonization of the catheter surface and formation of a superficial biofilm layer. the present study is aimed in developing an effective antibacterial device which can prevent colonization of organisms by modification of catheter. methods: in the present st...

in production of tissue paper, the adhesion of a liquid adhesive creping aid, compound polymer, as creping aids on the yankee dryer surface was investigated. a compound polymer was prepared based on mixing ratio of poly (amideamine)-epichlorohydrin resin (pae) as an adhesive agent, polyvinyl alcohol (pva) as a modifier agent, and cationic fatty acid (cfa) and ethylene glycol (eg) as release age...

We investigated the physical properties and tooth-whitening effect of polymeric compositions based on orally acceptable polymers, polyvinyl acetate (PVAc), ethyl cellulose (EC), pyrrolidone. The composition was prepared with hydrogen peroxide (H2O2) as a tooth-bleaching agent an polymer through simple mixing stirring in alcohol. PVAc EC polymers showed non-erosive features sustainable matrices ...
