چکیده
Epoxy resin has excellent mechanical and physical properties, which can be used in coatings, adhesives, and resin matrix composite. But the cured resin is usually friable, their fatiguedurability, the thermal stability, and resistance to impact are poor, and the electrical properties are not good enough. Theoretically, the carbon nanotubes addition can improve the mechanical properties and the electrical properties of the epoxy resin greatly, and expand the application ofepoxy resin to a larger extent. In this study multiwall carbon nanotubes were modified by acid oxidation as destructive method and feridel-craft acylation reaction as nondestructive method. Nanocomposites of Modified MWNTs and epoxy resins were obtained and their properties wereinvestigated. Results indicate that for mechanical properties both modified MWNTs behave almost similar but thermal conductivity of composites prepared with MWNTs which modified by acylation reaction several times is higher than acid oxidationکلیدواژه ها

اطلاعات بیشتر در مورد COI
COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
