Glass transition of thin films of poly(2-vinyl pyridine) and poly(methyl methacrylate): nanocalorimetry measurements
Glass transitions were observed in thin films of poly(2-vinyl pyridine) (P2VP) and poly(methyl methacrylate) (PMMA) using a scanning nanocalorimetry technique which has both high sensitivity (10−9 J/K) and high scan rates (104–105 K/s). Samples were deposited by the spin-cast method. The thickness of samples was 100–400 nm. Glass transition temperature, obtained by nanocalorimetry, is shifted t...
متن کاملEvaluation of morphology and cell behaviour of a novel synthesized electrospun poly(vinyl pyrrolidone)/poly(vinyl alcohol)/hydroxyapatite nanofibers
Objective(s): Three-dimensional structures such as nanofibrous scaffolds are being used in biomedical engineering as well as provide a site for cells to attach and proliferate leading to tissue formation. In the present study, poly(vinyl pyrrolidone) (PVP)/ poly(vinyl alcohol)(PVA) hybrid nanofibrous scaffold was synthesized by electrospinning. Materials and Methods: The effect of adding nano h...
متن کاملPoly(vinyl alcohol) gels as photoacoustic breast phantoms revisited.
A popular phantom in photoacoustic imaging is poly(vinyl alcohol) (PVA) hydrogel fabricated by freezing and thawing (F-T) aqueous solutions of PVA. The material possesses acoustic and optical properties similar to those of tissue. Earlier work characterized PVA gels in small test specimens where temperature distributions during F-T are relatively homogeneous. In this work, in breast-sized sampl...
متن کاملEffect of some additives on degradation of poly (vinyl chloride- co- vinyl
The thermal decomposition of 86 % vinyl chloride 14 % vinyl acetate copolymer wasstudied by the conductometry technique in the presence of nitrogen. The kinetics of stability andthermal degradation of vinyl chloride- co- vinyl acetate (PVC- co- PVAc) copolymer withcopper, copper oxide and tricalcium dicitrate (st) were investigated at various temperatures (150-180 oC ) in solution. The rate coe...
متن کاملWorker exposure to vinyl chloride and poly(vinyl chloride).
The National Institute for Occupational Safety and Health (NIOSH) in early 1974 began industrial hygiene studies of vinyl chloride exposed workers. Three VC monomer plants, three VC polymerization plants, and seven PVC fabrication plants were surveyed. V polymerization plant workers and workers in one job category in VC monomer plants were exposed to average levels above 1 ppm. The highest aver...
