Abstract

Termoplastik elastomerler (TPE), hızlı prototipleme sayesinde, araştırmacılara yumuşak ve jöle benzeri yapılardan sert ve rijit malzemelere kadar geniş bir tasarım imkânı sağlayabilme
kapasitesine sahiptir. Bu bağlamda, poli(stiren-b-(etilen-kobütilen)-b-stiren) (SEBS) triblok kopolimerleri birçok farklı olumlu özelliklere sahiptir ve farklı uygulamalar için cihazların tasarımı ve gereksinimleri düşünüldüğünde çok umut vericidir. SEBS triblock kopolimerinin termoplastik ve elastomerik özelliklerinin kombinasyonu büyük ölçekli malzemelerin üretiminde potansiyel malzemeden biridir. Bu çalışmada, elektro çekimin yararlarından faydalınarak SEBS triblock kopolimerden ortalama çapları 286±93 nm olan yüksek elastik ve fonksiyonel nanofiberler bildiğimiz kadarıyla literatüre göre ilk defa üretilmiştir. Elde edilen bu fonksiyonel elektrospan nanofiberlerinin yakın gelecekte tıbbi ve su arıtımı uygulamalarında yaygın olarak kullanılacağına inanıyoruz.

PRODUCTION AND ANALYSIS OF FUNCTIONAL SEBS NANOFIBERS BY ELECTROSPINNING

Abstract

Thermoplastic elastomers (TPE) offers wide design opportunities because of its rapid prototyping that provides researchers with the acquisition of many different material properties from softness and jelly-like properties to hardness and rigidity. In this regard, poly(styrene-b-(ethylene-cobutylene)-b-styrene) (SEBS) triblock copolymer has many positive aspects and is very promising when the design and requirements of devices for different applications are considered. The combination of thermoplastic and elastomeric properties of SEBS triblock copolymer makes it one of the potential materials in the production of large-scale materials. In this study, highly elastic and functional nanofibers from SEBS triblock copolymer with the diameters of 286±93 nm were produced successfully by electrospinning for the first time, to the best of our knowledge. We believe that SEBS-based functional electrospun nanofibers will find widespread applications in medicine and water purification in the near future
