چکیده
Cellulose is an important part of natural macromolecules, which is the most abundant organic compound on the earth. cellulose is a linear biopolymer, it tends to act as a thermosetdue to its frequent and strong interchain hydrogen bonds in the crystalline regions. The crystalline melting point of thecellulose is higher than its decomposition temperature. However, if the interchain H-bonds are disrupted by the introduction of nonpolar side chains, lignocelluloses can betransformed into processable materials. but it is possible by chemical modification, for example, reacting with analkylating or acylating agent, convert these substances into processable thermoplastic materials. also, many of these polymers has poorer thermal and mechanical propertiescompared to conventional thermoplastic.There are sure attempts to improve properties of thermoplast drive fromcellulose by compounding with nanoclayکلیدواژه 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.
