Effects of mixing sequence on epoxy/polyether polyol/organoclay ternary nanocomposites Isik-Gulsac, Isil; YILMAZER, ÜLKÜ; Bayram, Göknur (Informa UK Limited, 2020-09-01) The effects of mixing sequence of the polyether polyol and curing agent (triethylenetetramine) on mechanical and thermal properties and morphology of epoxy/polyether polyol/organoclay ternary nanocomposites are investigate...
Effect of halloysite nanotubes on multifunctional properties of coaxially electrospun poly(ethylene glycol)/polyamide-6 nanofibrous thermal energy storage materials Yilmaz, Refik Baris; Bayram, Göknur; YILMAZER, ÜLKÜ (Elsevier BV, 2020-08-01) Coaxial electrospinning of poly(ethylene glycol) (PEG)/polyamide 6 (PA6) was successfully used in development of nanofibrous thermal energy storage (TES) material. Halloysite nanotubes (HNTs) were introduced into the core/...
Synthesis of zinc borate using water soluble additives: Kinetics and product characterization ÇAKAL, GAYE ÖZGÜR; Baltaci, Berk; Bayram, Göknur; Özkar, Saim; EROĞLU, İNCİ (Elsevier BV, 2020-03-01) Zinc borate was synthesized from the reaction of zinc oxide and boric acid in the absence or presence of seven different water soluble additives. Additive concentration and zinc oxide particle size were varied to investiga...
Poly(methyl methacrylate) hybrid syntactic foams with hollow glass microspheres and polyhedral oligomeric silsesquioxanes Ozkutlu, Merve; Dilek Hacıhabiboğlu, Çerağ; Bayram, Göknur (Wiley, 2019-08-10) The study aims to produce poly(methyl methacrylate) (PMMA)-based lower density syntactic foams with hollow glass microspheres (HGMs) and to improve their mechanical properties by the addition of polyhedral oligomeric silse...
Effects of hollow glass microsphere density and surface modification on the mechanical and thermal properties of poly(methyl methacrylate) syntactic foams ÖZKUTLU DEMİREL, MERVE; Dilek Hacıhabiboğlu, Çerağ; Bayram, Göknur (Elsevier BV, 2018-10-15) Syntactic foams offer low density polymers for insulation and transportation applications with the advantage of having high mechanical properties. In this study, poly(methyl methacrylate) (PMMA) syntactic foams were produc...
