Abstract

Çalışmada naylon 6,6 nanolif membranlar elektroeğirme tekniği ile
üretilmiştir ve değişik çözücü sistemleri ile üretilmiş nylon 6,6 nanolif
membranların mekanik özellikleri incelenmiştir. Naylon 6,6 çözeltileri naylon
6,6 nın formik asit/trifloroetil alkol çözücü sisteminde 50/50, 75/25 ve 100/0
oranlarında çözünmesiyle hazırlanmıştır. Sonuçlar çözücü tipinin ortalama
nanolif çaplarında ve mekanik özelliklerde belirgin etkisi olduğunu
göstermiştir. Formik asit artışı düşük nanolif çaplarına ve artan mekanik
mukavemete neden olmuştur. Formik asit kullanılarak hazırlanan membran 400 nm
ortalama nanolif çapı ile 20MPa civarı mukavemet göstermiştir.

Mechanical Properties Of Nylon 6,6 Nanofiber Membranes

Abstract

 Nylon 6,6 nanofiber membranes were produced by electrospinning
technique and mechanical properties of the nylon 6,6 membranes prepared with
different solvent systems were investigated. Nylon 6,6 solutions were prepared
by dissolving nylon 6,6 in the solvent system of formic acid/trifluoroethyl
alcohol with the ratios of 50/50, 75/25 and 100/0 (v/v). Results showed that
solvent type has a pronounced effect on average fiber diameters and mechanical
properties. Increasing formic acid led to lower average fiber diameters and
enhanced mechanical strength. The nylon 6,6 membrane prepared by using formic
acid exhibited the tensile strength of about 20 MPa with the average fiber
diameter of about 400 nm.
