Abstract

The aim of this study is the determination of optimum process parameters which will provide the finest and the most uniform electrospun Polyvinylpyrrolidone (PVP) based nanofibers with Taguchi experimental design. For the designed experimental setup, parameters (solvent type, polymer concentration, voltage, distance between the electrodes, solution feed rate and humidity) were used which effect the electospinning process significantly. For this purpose, the appropriate orthogonal array was selected to determine the factors and levels at Taguchi experimental design application. The experimental design aimed which provides to be reduced the number of experiments and minimised the effect of uncontrollable factors with less experiments to obtain target value by using Taguchi orthogonal arrays. In the experimental studies of paper, firstly PVP polymer solutions such as conductivity, surface tension and viscosity were determined with various PVP concentrations (10, 12, 14 wt %) and solvents (ethanol, dimethylformamide, dimethylacetamide, chloroform, acetic acid and distilled water). Scanning Electron Microscope (SEM) images of electrospun PVP based nanofibrous surfaces were obtained, average fiber diameter and fiber diameter coefficient values were calculated by ImageJ image analyses software and fiber diameter distribution histogram curves were obtained by SPSS program. Experimental results were analyzed and commented by Taguchi method in MINITAB program with variance analysis. According to the results; solvent type has the highest effect on the electrospinning of PVP nanofibers. In this study, it is predicted to save in terms of time and cost with decreasing the number of experiments by Taguchi experiment design.

Elektro Lif Çekim Yöntemi ile PVP Nano Lif Üretimi ve Taguchi Deneysel Tasarımı ile Optimizasyonu

Abstract

Çalışmanın amacı; Taguchi deneysel tasarımı uygulanarak elektro lif çekimi yöntemi ile en ince ve en üniform Polivinilpirolidon (PVP) esaslı nano liflerin üretimini sağlayacak optimum proses parametrelerinin belirlenmesidir. Tasarlanan deney düzeneğinde elektro lif çekimine önemli ölçüde etki eden parametreler (çözücü çeşidi, polimer konsantrasyonu, voltaj, elektrotlar arası mesafe, çözelti besleme hızı ve nem) kullanılmıştır. Taguchi deney tasarımı uygulamasında, amaca uyan faktör ve seviyeler belirlenerek uygun ortogonal dizin seçilmiştir. Taguchi ortogonal dizinleri kullanılarak, hedef değere ulaşmak için yapılan deney sayısı azaltılmış ve daha az deneyle kontrol edilemeyen faktörlerin etkisini de en aza indirgeyen bir deney tasarımı amaçlanmıştır. Yapılan deneysel çalışmalarda öncelikle PVP polimeri kullanılarak farklı konsantrasyonlarda (% 10, 12, 14) hazırlanan çözeltilerin iletkenlik, yüzey gerilimi ve viskozite özellikleri ölçülmüştür. Elektro lif çekimi ile üretilen PVP esaslı nano lifli yüzeylerin Taramalı Elektron Mikroskobu (SEM) görüntüleri alınmış, Image J görüntü analiz programı kullanılarak ortalama lif çapı ve lif çapı üniformite katsayıları hesaplanmış ve SPSS programı ile çap dağılımı histogram eğrileri oluşturulmuştur. Deney sonuçları, varyans analizi kullanılarak MINITAB programında Taguchi yöntemiyle incelenerek yorumlanmıştır. Sonuçlara göre; elektro lif çekimi ile üretilen PVP nanolifler üzerinde çözücü tipi en fazla etkiye sahiptir. Bu çalışmada, Taguchi deneysel tasarımı ile deney sayısının azaltılmasıyla zaman ve maliyet bakımından kazanç sağlanması öngörülmektedir.
