摘要: Abstract Rice husk and rice ash are two well-known sustainable materials for wastewater purification applications. In this work, functionalized-rice -rice reinforced polyamide 6/graphene oxide nanocomposites fabricated using the solution casting method. 3-Aminopropyl-triethoxysilane is used as functionalizing agent surface modification of particles. Siloxane bonding between silanol groups silica containing particles can result in introduction amino on particles, which react with either terminal carboxyl or amide 6. Functionalized-rice ash, contains a large amount nano silica, forms distributed nano-sized aggregates structure Moreover, simultaneous presence graphene an organic/inorganic nano-system, matrix results clear enhancement structural mechanical characteristics final nanocomposites. This possible strong interactions polymeric nano-system. The influences nano-system melting process, morphology dynamic-mechanical properties investigated details. impacts loading thermal stability studied. Considering presented here adsorbent nanoparticles, ash/graphene oxide/polyamide 6 nanocomposite perfect candidate fabricating nanofibers, applicable
