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 ...
Temperature Effect on the Elasticity of Acrylamide-n-Isopropylacrylamide Copolymers
(Taylor & Francis Inc, 2018)
Acrylamide (AAm) - N-isopropylacrylamide (NIPA) copolymers were prepared via free radical crosslinking copolymerization with various weight percentages (wt%) of AAm and NIPA. The temperature dependence of the compressive ...
Optical energy band gap of PAAm-GO composites
(Elsevier Sci Ltd, 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 ...
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 ...
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 N,N'-methylenebis (acrylamide) (BIS) were used as a free ...
Effect of multiwalled carbon nanotube (MWNT) on the behavior of swelling of polyacrylamide-MWNT composites
(Sage Publications Ltd, 2014)
The purpose of this paper is to discuss the role of multiwalled carbon nanotube in the swelling of polyacrylamide-multiwalled carbon nanotube composites. Swelling experiments were performed in water at various temperatures ...
Drying of polyacrylamide-multiwalled carbon nanotube (MWNT) composites with various MWNTs contents: a fluorescence study
(Walter De Gruyter Gmbh, 2013)
We studied the drying of polyacrylamide (PAAm)-multiwalled carbon nanotube (MWNT) composites, prepared by free radical crosslinking copolymerization in water, with a steady state fluorescence technique. Composite gels were ...
The WS(2)dependence on the elasticity and optical band gap energies of swollen PAAm composites
(Sage Publications Ltd, 2021)
New generation nano-filler polymer composites have many applications including biomedical, electronic and maritime related applications because of their mechanical, electronic and optical properties. The properties of ...
Elastic Properties of a Swollen PAAm-NIPA Copolymer with Various NIPA Contents
(Taylor & Francis Inc, 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, ...
Gelation of PAAm-PVP composites: A fluorescence study
(World Scientific Publ Co Pte Ltd, 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) ...
