چکیده
In this study, lightweight open-cell micro- and nano-cellular poly(lactic acid) (PLA) foams with adensity of ۰.۳ g/cm۳ and cell density of ۱۰۷ cells/cm۳ were fabricated by using a NaCl filler throughthe twin-screw extrusion process. These foams were obtained through the filler leaching method andjust water and table salt were applied to prepare the foams. Highly-filled PLA/NaCl composites witha weight fraction of ۲۰:۸۰ were extruded. Then, the composites were immersed in water and after ۲۴hr, an open-cell cellular structure with a void content of ۷۲% was achieved. These foams were appliedto absorb pollutants like gasoline, diesel fuel, formaldehyde and ammonia. The objective of thisresearch has been the low-cost production of open-cell biodegradable foams for cleaning up marinepollution.کلیدواژه ها

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.
