Optical energy band gap of PAAm-GO composites
(Elsevier Science, 2018)
Graphene oxide (GO) can be used as an electron acceptor for polymers. The generation of the exciton in such materials is intimately related to the optical band gap. Polyacrylamide (PAAm) - graphene oxide (GO) composites ...
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 ...
Surfactant and Metal Ion Effects on the Mechanical Properties of Alginate Hydrogels
(Elsevier Science Bv, 2016)
This paper addresses the controlled variation of the mechanical properties of alginate gel beads by changing the alginate concentration or by adding different surfactants or cross-linking cations. Alginate beads containing ...
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 ...
Gelation electrical conductivity and elasticity of PAM- MWNT
(Cambridge Univ Press, 2011)
Polyacrylamide- Multiwalled carbonnanotube (PAM- MWNT) composites were prepared via free radical crosslinking copolymerization with different amounts of MWNT varying in the range between 0.1 and 15 wt. %. PAM- MWNT composite ...
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) ...
Elasticity Study of PAAm-kappa C Composite Prepared in Various kappa C Content and Measured at Several Temperatures
(Polish Acad Sciences Inst Physics, 2015)
Polyacrylamide (PAAm)-kappa carrageenan (kappa C) composite gels were prepared via free radical crosslinking copolymerization with various (w/v) percentages of kappa C in the range between 0.5 and 3 (w/v)% of kappa C . ...
Universality of elasticity on PAAM-NIPA copolymer gels
(EDP Sciences, 2015)
Polyacrylamide (PAAm)-N-isopropylacrylamide (NIPA) copolymers were prepared via free radical crosslinking copolymerization with different molar of NIPA varying in the range between 0 and 2 M. The mechanical properties of ...
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 ...
