Critical Exponents of Gelation and Conductivity in Polyacrylamide Gels Doped by Multiwalled Carbon Nanotubes
(Taylor & Francis Ltd, 2010)
Polyacrylamide (PAM) doped by multiwalled carbon nanotube (MWNT) gels were prepared with different amounts of MWNTs varying in the range between 0.1 and 15 wt%. The PAM-MWNT composite gels were characterized by the steady ...
Study of Thermal Phase Transitions in Iota Carrageenan Gels via Fluorescence Technique
(Wiley-Blackwell, 2011)
The effect of carrageenan concentration on thermal phase transitions of the iota carrageenan gels was investigated by using fluorescence technique. During heating and cooling processes scattered light I(sc) and fluorescence ...
Thermal Phase Transitions of Agarose in Various Compositions: A Fluorescence Study
(Springer/Plenum Publishers, 2011)
The effect of agarose content on thermal phase transitions of the agarose gels was investigated by using Steady State Fluorescence (SSF) method. Scattered light I(sc) and fluorescence intensity I(fl) were monitored against ...
Oxygen Diffusion into Multiwalled Carbon Nanotube Doped Polystrene Latex Films Using Fluorescence Technique
(Springer/Plenum Publishers, 2013)
This study examines the oxygen diffusion into polystyrene (PS) latex/multiwalled carbon nanotube (MWNT) nanocomposite films (PS/MWNT) consisting of various amounts of MWNT via steady state fluorescence technique (SSF). ...
Diffusion energies of oxygen diffusing into polystyrene (PS)/poly (N-isopropylacrylamide) composites
(Wiley-Blackwell, 2012)
Diffusion coefficient of oxygen penetrating into polystyrene (PS) latex/poly (N-isopropylacrylamide) (PNIPAM) microgel composite films were measured using Fluorescence technique. Three different (5 15 and 40wt%) PS content ...
Effect of LCST on the swelling of PAAm-NIPA copolymers: a fluorescence study
(Springer, 2012)
Temperature sensitive copolymers were prepared by free radical crosslinking copolymerization in aqueous solution with different molar percentage of N-isopropylacrylamide (NIPA) and acrylamide (AAm) monomers. NN'-methylenebis ...
Monitoring the gelation of polyacrylamide-sodium alginate composite by fluorescence technique
(Taylor & Francis Ltd, 2012)
Polyacrylamide (PAAm)-sodium alginate (SA) composite was prepared with different amounts of SA varying in the range between 0.06% and 2% (w/v). The PAAm-SA composite was characterized by the steady-state fluorescence ...
Gelation of PAAm-PVP composites: A fluorescence study
(World Scientific, 2014)
Hybrid hydrogels are a new class of composite materials. Polyacrylamide (PAAm) hydrogels are mainly produced by free radical crosslinking copolymerization (FCC) of AAm in the presence of N N'-methylene bis (acrylamide) ...
Measurement of oxygen diffusion in PS/PNIPAM films using fluorescence quenching
(Taylor & Francis Ltd, 2015)
The diffusion of oxygen into pyrene labelled polystyrene (PS) latex/poly(N-isopropylacrylamide) (PNIPAM) composite films (PS/PNIPAM) was studied based on PS content with the use of fluorescence quenching method. Fluorescence ...
Kinetic models for the dynamical behavior of polyacrylamide (PAAm)-kappa-carrageenan (kappa C) composite gels
(Springer, 2015)
A fluorescence method was employed for studying the drying and swelling of PAAm-kappa C composite gels which were formed from acrylamide (AAm) and N N'- methylenebisacrylamide (BIS) with various kappa-carrageenan (kappa ...
