· Potasyum persülfat, potasyum dikromat ve potasyum permanganatın grafitin oksidasyonuna etkileri incelenmiştir. XRD sonuçları grafitin oksidasyonunda potasyum permanganatın diğer oksidasyon ajanlarından daha etkili olduğunu göstermiştir.
· Grafitin oksidasyonunda ön oksidasyon işleminin önemli derecede etkili olmadığı gözlenmiştir.
· SEM görüntülerinden, grafitin keskin ve sıkıştırılmış tabakalara sahip bir yapıda olduğunu ve oksidasyon sonrası grafitin keskin ve sıkıştırılmış yapısının değiştiği (azaldığı) gözlenmiştir.
· Termal olarak 950˚C’de işlem görmüş grafen okside ait XRD sonuçları kısmi indirgenmenin olduğunu gösteriyor. SEM görüntüleri incelendiğinde indirgenmiş grafen oksit tabakaları arasındaki mesafenin grafen oksite kıyasla azaldığı gözlenmiştir.
· Hidrazin monohidrat ve termal yöntemle grafen oksitin indirgenmesi işleminde termal yöntemin daha etkili olduğu gözlenmiştir.
· Farklı pH’da yapılan deneylerde aramid fiberlere ait FT-IR spektrumları incelendiğinde, aramid fiberlerin yapısındaki alifatik aminlere spesifik olan 1100cm-1 deki sinyalin şiddetindeki değişimler nötral ve asidik ortamda hidroliz işleminin daha etkili olduğunu göstermiştir.
· Grafen oksit, indirgenmiş grafen oksit, aramid nanofiberler ve bu materyallerle oluşturulan kompozit maddeler ile yüksek yoğunluklu polietilen ve polipropilen polimerleri katkılanarak, kalıplara basılan kompozitlerin gerilme testleri incelendiğinde polimer/kompozit yapısında bulunan hava kabarcıklarının polimerin gerilme özelliğini olumsuz yönde etkilediği gözlenmiştir.
· Yüksek gerilme özelliğine sahip polimer eldesi için bu kabarcıkların oluşumunun engellenmesi gerekmektedir. Bunun için kompozit oluşturulma sırasında vakum destekli kalıpların kullanılması düşünülebilir.
