Bu çalışmada matris malzeme olarak poliamid 6 (PA 6), katkı malzemeleri ise yüksek yoğunluklu polietilen (YYPE), nanokil (NC) olarak modifiye edilmiş montmorillonit ve uyumlaştırıcı olarak Maleic Anhydrid Aşılanmış Polietilen (PE-g-MA) kullanılmıştır. Matris malzemesi olan PA 6’ya ilave edilen YYPE, nanokil ve uyumlaştırıcının kompozitin  termal özelliklerine olan etkisi araştırılmıştır. Malzemeye ilave edilen nano partiküllerin dağılımının nasıl olduğunu tespit etmek amacıyla Geçirimli Elektron Mikroskobu (TEM) ile inceleme yapılmıştır. Üretilen kompozitlerin termal özelliklerinin tespiti için vicat yumuşama sıcaklığı (VST), yük altında eğilme sıcaklığı (HDT), Diferansiyel Taramalı Kalorimetri (DSC) ve Termogravimetrik Analiz (TGA) deneyleri yapıldı.
