Abstract
Bu çalışmada, iki ve üç uçlu serilerinden oluşan farklı molekül ağırlığına sahip Jeffamin, p-formaldehit ve 2-naftol kullanılarak 1,4-diokzan varlığınde naftoksazin yapılı polimerler elde edildi. Sonuçta oluşan polimerler FTIR ve 1H-NMR ile karakterize edildi. Bununla beraber, polimerlerin kürleşme özellikleri DSC de oluşan ekzotermik pikleri (230-251 oC) ile kanıtlandı. Suyun kontakt açıları kullanılarak, polimerlerin (B-a monomeri ile) hidrofil özelliği ile naftoksazin fonksiyonlarının polimerler üzerindeki etkileri araştırıldı. Ayrıca polimerlerin yüzey topografileri AFM görüntüleri ile açıklandı.
In this study, naphtoxazine-functionalized polymers were prepared by the reaction of linear (Diamines) and branched (Triamines) reactive elastomer Jeffamine series having various molecular weights, with p-formaldehyde, and 2-naphthol [1,2]. The structures of the resulting polymers were characterized by FTIR and 1H-NMR. In addition, cure behavior of polymers were studied using DSC which indicated a single exothermic curing peak between 230-251 oC based on benzoxazine functionality. Hydrophilicity of polymers with B-a and effect of naphtoxazine functionality on hydrophilicity of these trunk polymers were investigated by water contact angle measurements. Also, Surface topography of polymers were represented by AFM images.
