In this study, the effect of relative humidity and temperature on the morphology of electrospun Poly(trimethylene terephthalate)
(PTT) fibers is investigated. It is also examined the interaction between these ambient parameters and those of some important
parameters such as charge density, tip to collector distance and flow rate. Dichloromethane (DCM) and trifluoroacetic acid (TFA)
solvent mixture is used. Field emission scanning electron microscopy (FESEM) is used for determination of surface morphologies and
average diameters of electrospun PTT fibers. The results show that average diameter of electrospun PTT fibers decreases with increasing
of relative humidity and temperature values for all of the charge density, tip to collector distance and flow rate values. The highest rate
of decrease is seen at 0.9 ml/h for increasing of RH from 30% to 70%. All of the obtained electrospun PTT fibers are circular shaped
with smooth surface without bead formation for all RH and temperature values.

ÇEVRESEL PARAMETRELERİN ELEKTROSPİN YÖNTEMİYLE ÜRETİLMİŞ POLİTRİMETİLEN TEREFTALAT LİFLERİNİN MORFOLOJİSİ ÜZERİNDEKİ ETKİLERİ

Öz

Bu çalışmada bağıl nemin ve ortam sıcaklığının elektrospin tekniğiyle üretilen politrimetilen tereftalat (PTT) liflerinin morfolojileri
üzerindeki etkileri incelenmiştir. Bununla birlikte bu çevresel parametrelerin; birim yük, toplayıcı-iğne ucu arası mesafe ve debi gibi
önemli proses parametreleriyle etkileşimleri de incelenmiştir. Çözücü olarak diklormetan (DCM) ve triflor asetikasit karışımı
kullanılmıştır. Elektrospin yöntemiyle üretilen PTT liflerinin yüzey morfolojileri ve ortalama çaplarının analizi için alan emisyonlu
taramalı elektron mikroskobu (FESEM) kullanılmıştır. Elde edilen sonuçlara göre incelenen her üç proses parametresi (birim yük,
toplayıcı-iğne ucu arası mesafe ve debi) için hem bağıl nemin hem de sıcaklığın artması elektrospin tekniğiyle üretilen PTT liflerinin
ortalama çaplarını azaltmaktadır. En yüksek azalma oranı 0.9 ml/sa debide bağıl nemin 30%’dan 70%’e çıkmasında görülmüştür. Tüm
bağıl nem ve tüm sıcaklık değerleri için elektrospin tekniğiyle üretilen PTT liflerinin hepsinin dairesel yapıda, düzgün yüzeyli ve
boncuksuz olduğu görülmüştür.
