Abstract

Adding of various active agents to polymer solutions is a common application in order to provide different functional properties to nanofibers produced by electrospinning method. Gallic acid, which is natural phenolic acid and found in various plants, can be used as additive for nanofibers due to its advantageous characteristics (anti-inflammatory, antioxidant etc.). In the study, polyvinyl alcohol/distilled water solutions containing gallic acid with different ratios were prepared and the solutions’ characteristics (surface tension, conductivity, viscosity) were measured. Then, the nanofibers were produced from those solutions via electrospinning method. The morphology of the electrospun nanofibers were investigated by field emission scanning electron microscopy (SEM). Also, average fiber diameter and variations were calculated via an image analysis software. Increasing of viscosity and decreasing of conductivity of the solutions were seen when GA ratio was increased. However, there was no effect of GA ratio on surface tension of the solutions. Additionally, increasing of GA ratio caused to increase of average fiber diameter.

Özet

Elektro çekim tekniği ile üretilen nanoliflere farklı fonksiyonel özellikler kazandırmak amacıyla, polimer çözeltilerine farklı aktif maddelerin eklenmesi yaygın olarak yapılan bir uygulamadır. Birçok bitkide bulunan ve doğal bir fenolik asit olan gallik asit (GA) sahip olduğu avantajlardan (antienflamatuvar, antioksidan vb.) dolayı nanolifler içerisinde katkı maddesi olarak kullanılabilmektedir. Çalışmada, öncelikle farklı oranlarda GA içeren polivinil alkol/deiyonize su çözeltileri hazırlanmış ve çözelti özellikleri (yüzey gerilimi, iletkenlik, viskozite) tespit edilmiştir. Daha sonra bu çözeltilerden elektro çekim yöntemiyle nanolifler üretilmiştir. Üretilen nanoliflerin morfolojisi, alan emisyonlu taramalı elektron mikroskobu (FE-SEM) kullanılarak incelenmiştir. Ayrıca bir görüntü analiz yazılımı kullanılarak ortalama nanolif çapları ve çap dağılımları ölçülmüştür. GA oranı arttıkça çözelti viskozitesinin arttığı ve elektriksel iletkenliğinin azaldığı görülmüştür. Buna karşın, GA oranının çözeltilerin yüzey gerilimleri üzerinde net bir etkisi olmamıştır. Ayrıca GA oranının artması ortalama nanolif çapının artmasına neden olmuştur.
