Abstract

   Bu çalışmada, Poliamid 6/Grafen Nanotabakalı
(PA6/GNP) kompozitlerin yapısal ve termo-mekanik özelliklerine dolgu maddesi
olarak kullanılan nanotabakalı grafen partiküllerinin etkisi incelenmiştir. Bu
amaçla çift vidalı ekstrüzyon cihazı ile eriyik harmanlama yöntemi kullanılarak
PA6/GNP kompozitleri hazırlanmıştır. Kompozitler enjeksiyonlu kalıplama yöntemi
kullanılarak test numunesi haline getirilmiştir. XRD ve DSC analiz sonuçları γ
kristal fazının kompozitlerde baskın olduğunu göstermiştir. GNP katkılı PA6
kompozitlerin katkısız PA6’ ya göre termal olarak daha kararlı oldukları TGA
analiz sonuçları ile belirlenmiştir. Kompozitlerin yeni ve baskın kristal
yapıları sayesinde termo-mekanik özelliklerinin iyileştiği sonucuna
ulaşılmıştır.

CHARACTERIZATION OF THERMO-MECHANICAL PROPERTIES OF POLYAMIDE 6/GRAPHENE NANOPLATES (PA6/GNP) COMPOSITES

Abstract

   In this study, the effect of
Graphene Nanoplates (GNP) as filler on the structure and thermo-mechanical
properties of the Polyamide 6/Graphene Nanoplates (PA6/GNP) composites was
investigated. For this
purpose, PA6/GNP
composites were prepared through a melt mixing method with twin screw extruder.
These composites were formed into test samples using the injection molding
method.
γ phase crystal form in the PA6/GNP composites was shown to be dominated by
XRD and DSC results. TGA analysis results indicated that the GNP filled PA6
composites were more thermally stable than the unfilled PA6. As a result, thermo-mechanical properties of PA6/GNP composites improved
due to the new and dominant crystal structural form.
