چکیده
Nanocomposites consisting of polyolefin’s matrix and organically modified montmorillonite (a layered silicate clay, OMMT) have received considerable attention from the scientist around the world, as they exhibit enhanced physical and mechanical properties at very low amounts of the filler, usually less than 5 wt % [1-2]. However, during the last few years several research groups [3-5] have reported that incorporation of the clay nano-particles into PE or PP accelerates photo-oxidative degradation of these polymers.In the present work the efficiency of OMMT in promoting the rate of photo-oxidation degradation of LDPE films upon exposure to sunlight has been investigated in comparison with that of a conventional photoactive additive: benzophenone (BP). It was the purpose of this study to find out if OMMT is as much as effective that can be used as a photosensitizer additive for combating pollution caused by LDPE film as packaging disposals.کلیدواژه 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.
