PAAm-kappa carrageenan composites: drying and swelling with various kappa carrageenan contents
(Polish Acad Sciences Inst Physics, 2012)
The purpose of this study is to discuss the role of kappa-carrageenan (kappa-car) in the drying and swelling of polyacrylamide (PAAm)-kappa-car composite. The fluorescence intensity of pyranine increased and decreased as ...
Film Formation of Poly (methyl methacrylate) Latex With Pyrene Functional Poly (divinylbenzene) Microspheres Prepared by Click Chemistry
(Wiley-Blackwell, 2011)
This work reports on the application of steady state fluorescence (SSF) technique for studying film formation from poly(methyl methacrylate) (PMMA) latex and poly(divinylbenzene) (PDVB) microsphere composites. Pyrene (P) ...
Studies on Drying and Swelling of PAAm-NIPA Composites in Various Compositions
(Wiley-Blackwell, 2011)
The steady-state fluorescence technique was introduced for studying the drying and swelling of disc-shaped PAAm-NIPA composites. Disc-shaped gels were formed with various acrylamides (AAm) and N-isopropylacrylamides (NIPA) ...
Drying of Polyacrylamide Composite Gels Formed with Various Kappa- Carrageenan Content
(Springer/Plenum Publishers, 2011)
Drying of polyacrylamide (PAAm)-kappa-carrageenan (kappa C) composite gels were monitored by using steady-state fluorescence technique. Disc shaped gels were formed from acrylamide (AAm) and N N'- methylenebisacrylamide(Bis) ...
Fluorescence study on drying of iota-carrageenan gels at different temperatures prepared with various CaCl2 content
(Springer, 2011)
The influence of temperature and salt content on drying was investigated by using steady-state fluorescence (SSF) technique. Supporting gravimetric and volumetric measurements were also carried out during drying of gels ...
A comparison of fluorescence and UV-visible spectrometry techniques for thermal phase transitions of agarose gels
(Springer, 2015)
In this study thermoreversible phase transitions of high (HMP) and low (LMP) melting point agarose gels were investigated by using the UV-vis and fluorescence spectroscopy techniques. Pyranine was added to the aqueous ...
Spectroscopic study of film formation from polystyrene latex/TiO2 nanocomposites prepared by dip-coating method
(Wiley-Blackwell, 2014)
In this study we investigated the influence of TiO2 content and thickness of polystyrene (PS) template on film-formation behavior of PS/TiO2 composites using fluorescence and ultraviolet-visible techniques in conjunction ...
Electrical optical and fluorescence percolations in P(VAc-co-BuA)/MWCNT composite films
(Taylor & Francis Ltd, 2013)
Effects of multiwall carbon nanotube (MWCNT) addition on the electrical conductivities optical transparencies and fluorescence emissions of poly(vinyl acetate-co-butyl acrylate) (P(VAc-co-BuA))/MWCNT composite films were ...
Particle Size Effect on the Film-Forming Process of PS/PBA Composite Latexes
(John Wiley & Sons Inc, 2010)
In this work the effect of hard particle size and blend ratio on the film formation behavior of hard polystyrene (PS) and soft poly(n-butyl acrylate) (PBA) latex blends was studied by means of steady-state fluorescence and ...
Comparison of cation effects on phase transitions of kappa and iota carrageenan
(European Polymer Federation, 2010)
Phase transitions of kappa and iota carrageenan in KCl NaCl and CaCl2 solutions were separately studied during heating and cooling processes by using fluorescence technique. Scattered light I-SC and fluorescence intensity ...
