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 ... -
In situ steady state fluorescence (SSF) technique to study drying of PAAm hydrogels made of various cross-linker contents
(Elsevier Science, 2009)Drying experiments of polyacrylamide (PAAm) gels were performed using steady-state fluorescence (SSF) spectrometer. Pyranine (P) was introduced as a fluorescence probe and intensity of P from various crosslinker content ... -
Kinetics models for polyacrylamide-graphene oxide composites as antifoulant
(Wiley, 2023)Antifouling paints are used to protect the surface against these organisms such as algae, sea squirts, and barnacles. According to previous research, fish and seaweeds do not adhere to submerged surfaces using wet and soft ... -
Optical, Mechanical, and Electrical Properties of Polymer Composites Doped by Multiwalled Carbon Nanotubes
(Intechopen, 2016)Three-dimensional networks can be hydrophilic and/or hygroscopic. Optical, mechanical, and electrical properties of these materials encompass many fields of technology. Composites of carbon nanotubes (CNTs) in polymeric ... -
Phase Transitions in Pure and Hybrid Hydrogels: A Fluorescence Study
(Wiley, 2009)Recent observations on phase transitions around the critical point showed that the critical exponents differed drastically from percolation results and classical results for pure hydrogel systems depending on monomer ... -
Polyacrylamide mediated polyvinyl pyrrolidone composites incorporated with aligned molybdenum disulfide
(Wiley, 2022)In this study, we aimed to design a mechanically durable material consisting of Molybdenum disulfide (MoS2) as 2D material and polyvinyl pyrrolidone (PVP) enhanced Polyacrylamide (PAAm) composites. Composites containing ... -
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 ... -
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 ... -
Tungsten disulfide (WS2) doped polyacrylamide (PAAm) composites: Gelation and optical studies
(Elsevier Gmbh, 2021)The organic Acrylamide (AAm) copolymerization in various contents of inorganic WS2 has been reported. The aim was to investigate the effect of the WS2 amount on the obtained morphology and the gelation process of the AAm ...
