PANI Konsantrasyonunun PP/PANI Kompozitlerinin Mekanik Özelliklerine Etkisi
Bu çalışmada, farklı konsantrasyonlarda (ağırlıkça %0,3-%3,0 arası) Polyanilin (PANI) katkısının Polipropilen/Polyanilin (PP/PANI) film kompozitlerinin mekanik özelliklerine etkisi araştırılmıştır. Sıcak presleme tekniği ile elde edilen kompozit filmlerin, yüzey özellikleri ve yapısal morfolojileri (SEM ve FT- IR), termal özellikleri (TG) belirlenmek üzere karakterize edilmiştir. PANI katkısının polipropilen filmlerin mekanik özelliklerine etkisi çekme testleri ile incelenmiştir. Özellikle, kompozitlerin çekme dayanımı, Elastisite modülü ve yüzde kopma uzama miktarları test edilmiştir. Sonuçlarımıza göre, PANI katkısının polipropilenin mekanik özelliklerinde belirgin bir etkisi olduğu görülmüştür. Çekme gerilimi, PP/0.6 wt.% PANI kompozitlerinde en yüksek değere ulaşılmıştır.
The Effects of PANI Concentration on the Mechanical Properties of PP/PANI Composites
In this study, the effect of PANI additive with different concentrations (0.3-3.0 wt.%) on mechanicalproperties of Polypropylene/Polyaniline (PP/PANI) film composites have been investigated. Thecomposites films obtained from the hot pressing technique have been characterized to determine theirsurface properties and structural morphology (SEM and FT-IR), thermal properties (TG). The effects ofPANI additive on mechanical properties of polypropylene have been examined by tensile tests. Inparticular, tensile strength, Young's modulus and percentage strain at break of the composites havebeen tested. According to our results, it has been observed that the PANI additive in polypropylene hada significant impact on its mechanical properties. The tensile strength has been reached highest value inPP/0.6 wt.% PANI composites.
