Mechanical properties of graphene oxide-polyacrylamide composites before and after swelling in water
(Springer, 2018)
Polyacrylamide (PAAm) hydrogels have been proposed for use as promising biomaterials in biomedical and tissue engineering but their poor mechanical and water-retention properties have hindered their development. Graphene ...
Swelling Kinetics of PAAm-kappa-Carrageenan Composites: A Fluorescence Technique
(Taylor & Francis Inc, 2011)
The steady-state fluorescence (SSF) technique was introduced for studying swelling of disc-shaped polyacrylamide (PAAm) gels containing various amount of kappa-carrageenan (kappa C). They were prepared by free-radical ...
Modelling of Swelling by the Fluorescence Technique in Kappa Carrageenan Gels
(Amer Inst Physics, 2011)
Kappa (-kappa) carrageenan gels prepared with various carrageenan concentrations in pure water were completely dried and then swelled in water vapor. Steady state fluorescence measurements were performed using a spectrometer ...
Temperature effect on the swelling of PAAm-kappa-carrageenan composites
(Wiley-Blackwell, 2012)
The steady-state fluorescence (SSF) technique was used for studying swelling of disc-shaped polyacrylamide (PAAm)-kappa-carrageenan (kappa C) composites which were prepared by free-radical crosslinking copolymerization at ...
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 of dynamical processes in PAAm-MWNTs composites by fluorescence method
(Taylor & Francis Ltd, 2012)
Polyacrylamide (PAAm)-multi walled carbon nanotube (MWNT) composites were prepared by free radical cross-linking copolymerization in water. Ammonium persulfate and NN'-methylenebis (acrylamide) (BIS) were used as a free ...
A Fluorescence Study on Swelling of Hydrogels (PAAm) at Various Cross-Linker Contents
(Wiley, 2009)
Disk-shaped acrylamide (AAm) gels were prepared from AAm with various NN'-methylenebisacrylamide (Bis) contents as cross-linker in the presence of ammonium persulfate as an initiator by free-radical cross-linking ...
Group behaviour in physical chemical and biological systems
(Indıan Acad Scıences, 2014)
Groups exhibit properties that either are not perceived to exist or perhaps cannot exist at the individual level. Such 'emergent' properties depend on how individuals interact both among themselves and with their surroundings. ...
Elastic Properties of a Swollen PAAm-NIPA Copolymer with Various NIPA Contents
(Taylor & Francis, 2014)
Copolymer based on cross-linked polyacrylamide (PAAm) having N-isopropylacrylamide (NIPA) was prepared and their elastic properties were studied as a function of NIPA contents. NIPA content dependency of the shear modulus ...
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 ...
