چکیده

In order to provide coated textiles with a hydrophobic surface attempts were made to create structures similar to lotus leaves by generating the structures that using two phase separation of cellulose and alkyl silane blend solutions. Morphology of the so formed structures depends on the coagulation conditions. Resulting dimensions of these structures are influenced by the cellulose derivative substituent, the reaction time ratio and the coagulation by acid and temperature. In general, blends with cellulose acetate form the polymer blend solutions qualify for coating woven fabrics. A well-formed surface structure was obtained from WG/TEOS blends. The hydrophobicity was enhanced by either adding an alkyl silane to the coating compound. In order to prepare the hydrophobic coating, by a precursor sol comprising of Water Glass, and metal alkoxide such as tetraethyl orthosilicate (TEOS), a solvent, a basic catalyst and water, depositing the precursor sol as a film onto a fabric surface, such as a substrate. A hydrophobic silane compound to form a hydrophobic coating with a contact angle greater than approximately 90.0 degree. The morphology of surface was characterized by SEM image

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.
