Öz

Nanokil ve mikrokristalen selülozun (MCC) polimer matrisi içersinde etkili bir şekilde dağılımını sağlamak

için maleik anhidrit graftlanmış polietilen (MAPE) uyumsuzluk giderici olarak kullanılmıştır. PE‐g‐MA

ilaveli MCC ve nanokil esaslı yüksek yoğunluklu polietilen (YYPE) kompozitler tek vidalı ekstruder,

genişlemeli akışlı karıştırıcı ve masterbatch yöntemi ile üretilmişlerdir. MCC ve nanokil ilaveli yüksek

yoğunluklu polietilen (YYPE) kompozitlerin çekme, eğilme ve darbe dayanımı özellikleri belirlenmiştir.

MCC ilaveli yüksek yoğunluklu polietilen (YYPE) kompozitlerle karşılaştırıldığında, nanokil ilaveli yüksek

yoğunluklu polietilen kompozitlere uyumsuzluk gidericinin ilavesi ile daha yüksek çekme ve eğilme

direnci değerleri bulunmuştur. En yüksek çekme ve eğilme direnci değerleri %4 PE‐g‐MA ilaveli MCC

esaslı YYPE kompozitinden elde edilmiştir.

Anahtar Kelimeler
