MİKRODALGA ENERJİSİ YARDIMIYLA HİYERARŞİK YAPILI KARBON NANOTÜP/KARBON LİFİ KOMPOZİTLERİNİN ÜRETİLMESİ

Zahmetsiz, sade ve basit buna rağmen oldukça verimli, hesaplı ve kısa süreli (30 s) mikrodalga enerjisi tabanlı bir ısıtma işlemi kullanılarak; yüzeyini çok duvarlı karbon nanotüplerin ormanımsı bir tabaka halinde kapladığı karbon liflerinden oluşan hiyerarşik yapıdaki kompozitler ortam koşullarında tek adımda üretilmiştir. Üretilen bu kompozit yapıların morfolojik özellikleri, taramalı ve geçirimli elektron mikroskopları kullanılarak ve elementel analiz yardımıyla detaylıca test edilmiştir. Hem elde edilen kompozit malzeme özelliklerinin test sonuçları hem de bahsedilen bu işlemin çok yönlü ve kolaylıkla kontrol edilebilir sistematiği, yöntemin, yeni nesil ileri mühendislik uygulamalarında etkin olarak kullanılabilecek bu tip hiyerarşik yapıdaki kompozitlerin üretilmesindeki umut

Microwave Energy-Assisted Fabrication of Hierarchically Structured Carbon Nanotube/Carbon Fiber Composites

Through a facile, simple, yet efficient, affordable and ultrafast (30 s) microwave (MW) energy heating process, hierarchical composites made up of carbon fibers (CFs) decorated with multi-walled carbon nanotube (MWCNT) forest were produced at ambient conditions in one-step. Morphological features of the as-produced composites were characterized in details by using scanning and transmission electron microscopy (SEM, TEM) and the elemental analysis (EDX) techniques. Both the composite material characterization results and the versatile and easily controllable nature of the above mentioned process strongly support its promising success for the fabrication of such hierarchical composites that could be effectively used for the next generation advanced engineering applications.
