چکیده

The highly lightweight and thermal insulator polyvinyl alcohol (PVA) doped fiber-embedded silica aerogel blankets was prepared with different types of fibers. The performances of PVA-doped silica aerogel blankets were compared. The silica aerogel blankets were prepared by integrating different fibers with encapsulated the PVA during the aging process. The synergic effect of PVA doping-derived silica aerogel blankets on the thermal conductivity, surface physical characteristics and young modulus were investigated. Consequences revealed that PVA-encapsulated blankets could diminish the thermal conductivity, porosity, and density of the aerogel blanket. The prepared blankets have shown further properties intensely without significant reduction. Experimental outcomes exhibited the properties of improvement in thermal conductivity (in the range of ۰.۰۲۳-۰.۰۳۵ W/m.K), density (in the range of ۰.۰۵۱ - ۰.۱۱۸ g/cm۳), and Young Modulus regarding the pure silica aerogel. The prepared PVA-based aerogel blanket has prospective in various sectors such as the production of spacecraft apparel, military jackets, clothes for fire-fighting and hilly areas people from low-temperature protection.

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.
