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 ...
Film Formation of Nano-Sized Hard Latex (PS) in Soft Polymer Matrix (PBA): An Excimer Study
(John Wiley & Sons Inc, 2010)
This work reports steady state fluorescence (SSF) technique for studying film formation from pyrene (P)labeled nano-sized polystyrene (PS) and poly(n-butyl acrylate) (PBA) hard/soft latex blends. Blend films were prepared ...
Conductivity percolation of carbon nanotubes (CNT) in polystyrene (PS) latex film
(Canadian Science Publishing Nrc Research Press, 2010)
In this study the effect of multiwalled carbon nanotubes (MWNT) on film formation behaviour and electrical conductivity properties of polystrene (PS) latex film was investigated by using the photon transmission technique ...
Electrical and optical percolations of polystyrene latex-multiwalled carbon nanotube composites
(Academic Press Inc Elsevier Science, 2010)
Electrical conductivity and optical transmittance properties of polystyrene (PS)-multiwalled carbon nanotube (MWCNT) composite films were investigated. Composite films were prepared by mixing of various mass fractions of ...
Drying process in vapor swollen heterogels
(Springer, 2010)
Disk-shaped heterogels were prepared by combining methyl methacrylate (MMA) and styrene (S) with ethylene glycol dimethacrylate (EGDM) as a crosslinker agent in the presence of 22'-azobisisobutyronitrile (AIBN). Swelling ...
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 ...
Critical phenomenon during photoinitiated gelation at different temperatures: A Photo-DSC study
(Elsevier Science, 2011)
The behaviour of photoinitiated radical polymerization of an 80 wt% epoxy diacrylate (EA) and 20 wt% tripropyleneglycoldiacrylate (TPGDA) mixture with 2-mercaptothioxanthone (TX-SH) photoinitiator was studied at different ...
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 ...
Fractal Features and Structural Morphological Optical Characteristics of Sol-Gel Derived Silica Nanoparticled Thin Films
(Polish Acad Sciences Inst Physics, 2018)
Nanostructured silica films using a simple and effective sol-gel spin coating technique were synthesized and the influence of ammonia/sol ratios on the particle size and thickness of this film was investigated. In addition ...
Epidemic models for phase transitions: application to a physical gel
(Taylor & Francis Ltd, 2017)
Carrageenan gels are characterized by reversible sol-gel and gel-sol transitions under cooling and heating processes and these transitions are approximated by generalized logistic growth curves. We express the transitions ...
