Nanokil katkılı poliamid 6 / yüksek yoğunluklu polietilen kompozitlerin termal özelliklerinin incelenmesi

Bu çalışmada, matris malzeme olarak poliamid 6 (PA 6)'ya ilave edilen yüksek yoğunluklu polietilen(YYPE), nanokil (modifiye edilmiş Montmorillonite) ve uyumlaştırıcının (Maleic Anhydrid AşılanmışPolietilen, PE-g-MA), üretilen kompozitin termal özelliklerine olan etkileri araştırılmıştır. Malzemeyeilave edilen nano partiküllerin dağılımının nasıl olduğunu tespit etmek amacıyla Geçirimli ElektronMikroskobu (TEM) ile inceleme yapılmıştır. Üretilen kompozitlerin termal özelliklerinin tespiti için, vicatyumuşama sıcaklığı (VST), yük altında eğilme sıcaklığı (HDT), Diferansiyel Taramalı Kalorimetri (DSC)ve Termogravimetrik Analiz (TGA) deneyleri yapılmıştır. Deney sonuçları, ilave edilen nanokil veuyumlaştırıcının miktarlarına bağlı değişen oranlarda, polimerik nanokompozitin VST sıcaklığınıdeğiştirdiğini göstermiştir. Nanokil ve uyumlaştırıcının polimerik nanokompozitin ergime ve yumuşamasıcaklıklarını yükselttiği, kütle kayıplarını arttırdığı ve ergime entalpisini değiştirdiği tespit edilmiştir.

Investigation on thermal properties of nanoclay added polyamide 6 / high density polyethylene (HDPE) composites

In this study, the effects of HDPE (High Density Polyethylene), compatibilizer (Maleic anhydrides grafted polyethylene, PE-g-MA) and nanoclays (modified Montmorillonite) that are added to matrix material ofPA6 were investigated for the thermal properties of the prepared polymeric nanocomposites. The effect of HDPE, compatibilizer and nanoclays that are added to matrix material PA6 on the thermal properties of thecomposites were investigated. TEM investigation has been carried out to determine the agglomeration ofthe nanoparticles. to determine thermal properties of the produced composites, Vicat softening temperature(VST), Heat Deflection Temperature (HDT), Differential Scanning Calorimetry (DSC) andThermogravimetric Analysis (TGA) experiments were performed. The results of experiments showed thatnanoclay and compatibilizer with varying ratios change the VST temperature of the polymericnanocomposite. Also, the addition of nanoclay and compatibilizer was found to raise the melting andsoftening temperature of the polymeric nanocomposite, increase the loss of mass and change the enthalpyof melting.
