Abstract

Polylactic acid (PLA) is used as a potential polymer for consumer products and biomedical applications. With the increasing environmental and sustainability concerns associated with traditional petrochemical-based polymers, PLA applications continue to increase every day. Activated carbon (A.C.) is a substance obtained by carbonization of softwood parts such as linden and willow and is used as an antidote in industrial applications because it absorbs the toxin and prevents the absorption of toxins from the small intestine into the blood. It is a toxin absorber due to its adhesion to surfaces. A.C. the biggest problem with the fact that over time, the gaseous pollutants A.C. is a gradual filling of adsorption surfaces. In this study, PLA nanofibers reinforced with biyokompozit elektrospinning technique has been secured for the production and structural (FTIR, Fourier-Transform İnfrared Spectroscopy), morphological (FEGSEM, Field Emission Gun Scanning Electron Microscope), mechanical (Tensile Test) and biological (Cell Culture) by providing a characterization of the material properties were determined. With the obtained biocomposites, it will be able to be the ideal filtration material with a longer life and a large surface area that can be used in health sector applications.

Polilaktik Asit-Aktif Kömür Elektrospun Mat Üretimi ve Karakterizasyonu

Abstract

Polilaktik asit (PLA), tüketici ürünleri ve biyomedikal uygulamalar için potansiyel bir polimer olarak kullanılmaktadır. Geleneksel petrokimya bazlı polimerlerle ilişkili artan çevresel ve sürdürülebilirlik endişeleri ile PLA uygulamaları her geçen gün artmaya devam etmektedir. Aktif karbon (A.K.), ıhlamur ve söğüt gibi yumuşak ağaç kısımlarının karbonizasyonu ile elde edilen bir maddedir ve toksini emdiği ve toksinlerin ince bağırsaktan kana emilimini engellediği için endüstriyel uygulamalarda panzehir olarak kullanılmaktadır. Yüzeylere yapışması nedeniyle toksin emicidir. A.K. ile ilgili en büyük problem, zamanla gaz halindeki kirleticilerin A.K.'nin adsorpsiyon yüzeylerini yavaş yavaş doldurmasıdır. Yapılan bu çalışmada, elektroeğirme tekniği ile güçlendirilmiş PLA nanofiber biyokompozit üretimi sağlanmış olup, yapısal (FTIR, Fourier Dönüşümlü Kızılötesi Spektroskopi), morfolojik (FEGSEM, Alan Emisyon Tabancası Taramalı Elektron Mikroskobu), mekanik (Çekme Testi) ve biyolojik (Hücre Kültürü) karakterizasyonu sağlanarak malzeme özellikleri belirlenmiştir. Elde edilen biyokompozitler ile sağlık sektörü uygulamalarında kullanılabilecek daha uzun ömürlü ve geniş yüzey alanına sahip ideal filtrasyon materyali olabilecektir.
