Bu çalışmada biyo-bozunabilir polimerlerden polilaktik asit (PLA) içerisine oksitleyici, foto aktivite ve biyo-uyumluluk gibi gelişmiş özelliklere sahip nano boyutlu titanyum oksit (TiO2) katılarak biyo-analiz ve biyomedikal gibi uygulama alanlarında kullanılabilecek nano fiber üretimi elektro eğirme yöntemi kullanılarak gerçekleştirilmiştir. Nano boyutlu TiO2 parçacıkların PLA nano fiber içerisinde dağılımına elektro eğirme yöntem parametrelerinin etkileri detaylı olarak incelenmiştir. Elde edilen fiberlerin çapları ve morfolojik özellikleri taramalı elektron mikroskobu (SEM) ve yüksek çözünürlüklü geçirimli elektron mikroskobu (HRTEM) kullanılarak belirlenmiş, elementel analiz için enerji dağılım spektrometresi (EDS) kullanılmıştır. En iyi üretim koşulları 0.63 mm iğne çapında, 10 kV güç değerinde ve 0.3 ml/sa akış hızı şeklinde belirlenmiştir.
In this study, the nano-dimensional titanium oxide (TiO2) with advanced properties such as oxidant, photo activity and bio-compatibility from bio-dispersible polymers to polylactic acid (PLA) has been carried out using the nano-fiber production method that can be used in applications such as bio-analysis and biomedical. The effects of the parameters of the electro-wrapping method on the distribution of nano-dimensional TiO2 particles within the PLA nano fiber have been thoroughly studied. The diameter and morphological characteristics of the obtained fiber have been determined using the scaned electron microscope (SEM) and the high-resolution passing electron microscope (HRTEM), the energy distribution spectrometer (EDS) for elementary analysis has been used. Best Production Conditions: 0. It is determined at the 63 mm injection diameter, 10 kV power value and 0.3 ml/h flow speed.
In this study, nano-fiber production, which can be used in bio-analysis and biomedical applications by adding nano-sized titanium oxide (TiO2) with advanced properties such as oxidizing, photo activity and biocompatibility, from biodegradable polymers to poly lactic acid (PLA) was carried out by using electro spinning method. The effects of the electro spinning method parameters on the distribution of nano-sized TiO2 particles in PLA nano fiber were investigated in detail. The diameters and morphological properties of the obtained fibers were determined using scanning electron microscopy (SEM) and high resolution transmission electron microscopy (HRTEM), and energy dispersive spectrometry (EDS) was used for elemental analysis. Best production conditions were determined as; 0.63 mm needle diameter, 10 kV power and 0.3 ml / h flow rate.
