Abstract

This study investigated the effect of incorporating multi-walled carbon nanotubes (MWCNTs) into polypropylene/reed flour (PP/RF) composites, aiming to enhance their mechanical and physical performance. Composites were prepared using various MWCNT concentrations (0, 1, 2, 3, and 5 phr) and characterized through mechanical testing, water absorption analysis, and scanning electron microscopy (SEM). The addition of MWCNTs significantly improved flexural and tensile properties, with peak tensile strength observed at 2 phr (approximately 15% higher than the control) and maximum flexural strength at 3 phr (approximately 15% higher). Impact resistance was also highest at 2 phr (around 10% increase compared to control). Although mechanical performance declined at 5 phr due to MWCNT agglomeration, this formulation exhibited the lowest water absorption (approximately 12% reduction) and thickness swelling, indicating improved hydrophobicity. SEM micrographs confirmed better filler dispersion at lower concentrations and agglomerate formation at higher loadings. The results highlight the reinforcing potential of MWCNTs, particularly at 2-3 phr, in improving both structural strength and moisture resistance.

Özet

Bu çalışmada, çok katmanlı karbon nanotüplerin (MWCNT) polipropilen/kamış unu (PP/RF) kompozitlerine katılmasının mekanik ve fiziksel performans üzerine etkisi araştırılmıştır. Kompozitler, farklı MWCNT oranlarıyla (0, 1, 2, 3, ve 5 phr) hazırlanmış ve mekanik testler, su emme analizi ve taramalı elektron mikroskobu (SEM) ile karakterize edilmiştir. MWCNT ilavesi, özellikle eğilme ve çekme özelliklerinde belirgin iyileşmeler sağlamıştır; çekme mukavemeti 2 phr'de (yaklaşık 15% artış), eğilme mukavemeti ise 3 phr'de (yaklaşık 15% artış) en yüksek düzeye ulaşmıştır. Darbe dayanımı da 2 phr'da en yüksekti (kontrol ile karşılaştırıldığında yaklaşık %10 artış). MWCNT aglomerasyonu nedeniyle mekanik performans 5 phr'de düşmesine rağmen, bu formülasyon en düşük su emilimini (yaklaşık %12 azalma) ve kalınlık şişmesini göstererek hidrofobisitede iyileşme gösterdi. SEM mikrografları, daha düşük konsantrasyonlarda daha iyi dolgu dağılımı ve daha yüksek yüklemelerde aglomera oluşumunu doğruladı. Sonuçlar, MWCNT'lerin özellikle 2-3 phr'de hem yapısal dayanıklılığı hem de nem direncini iyileştirmede güçlendirme potansiyelini vurgulamaktadır.
