Summary: This paper provides an effective solution to achieve rapid and uniform introduction of GO in PAN-based nanofibers via in situ polymerization, and systematically studies the optimization of nanofiber structure by GO in three consecutive stages. The interaction between PAN and GO significantly improves the arrangement of PAN molecular chains and the crystal size of the final turbostratic structure of CNFs, leading to a remarkable increase in tensile strength of CNFs with the addition of GO.

Summary: Nanohybrids with less toxicity and excellent antibacterial activity, such as zinc oxide@graphene oxide (ZnO@GO), have been investigated in this study. The ZnO@GO nanohybrid was fabricated using the co-precipitation method, resulting in a homogeneous dispersion of ZnO particles on graphene oxide. The antibacterial efficacy of ZnO@GO was found to be higher than that of ZnO, indicating the potential of nanohybrids for developing effective bactericidal agents.

Summary: Cellulose is an abundant organic substance with various applications such as paperboard production, drug delivery, and food packaging due to its bio-renewable and bio-degradable properties. Radical polymerization is commonly used to create cellulose derivatives with improved properties, by reacting cellulose with small organic fragments like methacrylate and styrene. Initiators like Fenton's reagent and controlled radical polymerization methods are utilized to generate free radicals on the cellulose backbone for grafting purposes, allowing for the development of functional cellulose with enhanced physical and chemical properties.
