Lamine edilmiş Poli(laktik asit)/Keten Biyokompozitlerin Biyobozunurluk Özelliklerinin İncelenmesi

Abstract

Bu çalışmada mekanik özellikleri nispeten yüksek, ucuz ve ulaşılabilir bir biyopolimer olan PLA (poli(laktik asit)) matrisli, örülmüş ham keten takviyeli bir biyokompozit üretilmiştir. PLA matrisine kırılganlığını azaltıp sünekliğini arttırmak için %20 PBS (polibütilen süksinat) katkısı yapılmıştır. Saf PLA ve PLA/PBS karışımı 190°C sıcaklıkta enjeksiyon kalıplama yöntemi ile plakalar halinde üretilmiştir. Matris ve takviye fazının arayüzey yapışmasını iyileştirmek için kullanılan keten elyafa %5 NaOH (Sodyum hidroksit) kullanılarak alkali muamelesi yapılmıştır. Biyokompozitler 160°C’de sıkıştırma kalıplama yöntemi ile üretilmiştir. Üretilen biyokompozitlerin su emme ve biyobozunma kapasiteleri analiz edilmiştir. FT-IR (Fourier Dönüşümlü Kızılötesi Spektroskopisi) ve SEM (Taramalı Elektron Mikroskobu)-EDX (Enerji Dağıtıcı X-ışını) analizleri ile keten elyafın, yüzey modifikasyonu öncesi ve sonrası, yüzey özellikleri incelenmiştir. Yapılan analiz ve testler sonucunda %5 NaOH kullanılarak yapılan alkali muamelesinin iyi bir arayüzey yapışması sağladığı, nem emme kapasitesini ve toprakta bozunma sürecini artırdığı tespit edilmiştir.
