Critical phenomenon during photoinitiated gelation at different temperatures: A Photo-DSC study
Authors:Dogruyol, Zekeriya; Arsu, Nergis; Dogruyol, Sevnur Keskin; Pekcan, Önder
Publisher and Date:(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 temperatures by using photo-differential scanning calorimetric (Photo-DSC) technique. All photopolymerization reactions were carried out under the same conditions. It was observed that all conversion curves during gelation at different temperatures present nice sigmoidal behaviour ...

Investigation of PSt-MWCNT concentration on epoxyacrylate photopolymerization and conductivity of polymer films
Authors:Dogruyol, Zekeriya; Temel, Gokhan; Dogruyol, Sevnur Keskin; Pekcan, Önder; Arsu, Nergis
Publisher and Date:(Elsevier Science SA, 2013)Photopolymerization kinetics and conductivity changes of epoxyacrylate composites for various loading modified PSt-MWCNT weight fractions changing from 0.0025 to 0.2 wt.% were evaluated by performing photo differential scanning calorimetry (photo-DSC) and four point conductivity measurements. 0.2% PSt-MWCNT additive polymeric films had their electrical conductivity boosted by 6% more than non-additive polymeric films.

Producing critical exponents from gelation for various photoinitiator concentrations; a photo differential scanning calorimetric study
Authors:Dogruyol, Zekeriya; Arsu, Nergis; Dogruyol, Sevnur Keskin; Pekcan, Önder
Publisher and Date:(Elsevier Science SA, 2012)Photoinitiated radical polymerization of an 80 wt% epoxy diacrylate (EA) and 20 wt% tripropyleneglycoldiacrylate (TPGDA) mixture with various 2-Mercaptothioxanthone (TX-SH) photoinitiator concentrations was studied by using photo-differential scanning calorimetric (Photo-DSC) technique. Photopolymerization reactions were carried out under the same conditions of temperature and light intensity. It was observed that all conversion curves during gelation at various photoinitiator concentration present ...
