چکیده

پوشش‌های سطح مهندسی‌شده برای حفاظت پنبه در برابر آتش، به دلیل سهولت استفاده و اثربخشی آنها در جلوگیری از انتشار شعله و بهبود مقاومت در برابر قرار گرفتن در معرض شار حرارتی تابشی در حال افزایش است. در این زمینه، دو رویکرد اصلی در مهندسی سطح به‌طور گسترده مورد بررسی قرار گرفته‌اند، یعنی پوشش‌های مشتق شده از سل- ژل و ساختارهای لایه به لایه. از دیگر سو، این روش‌ها هر دو قادر به ارائه پارچه‌های اصلاح‌شده با ویژگی‌های برجسته مقاوم در برابر شعله هستند. باوجوداین، با توجه به ترکیب دستورالعمل‌های سل-ژل و نوع لایه‌های رسوب داده‌شده در ساختارهای لایه به لایه، می‌توان روش‌های اصلاح چندمنظوره (به‌عنوان‌مثال آب‌گریز، روغن‌گریز، خو‌د‌تمیز شونده، ضد‌باکتری، هدایت الکتریکی و غیره) را طراحی کرد. از این رو، این مقاله با هدف بحث در مورد پیشرفت‌های اخیر در رابطه با هر دو استراتژی سل-ژل و ساختارهای لایه به لایه، برجسته‌سازی محدودیت‌های فعلی، چالش‌ها و پیشرفت‌های احتمالی نگاشته شده‌است. به‌علاوه، تلاش شده‌است به مرور اجمالی از کارهای انجا‌‌م شده در این زمینه پرداخته شود.

چکیده [English]

Surface-engineered coatings for the fire protection of cotton are being increasingly used thanks to the ease of application of the coatings and their effectiveness in preventing flame propagation and improving resistance to irradiative heat flux exposure. Two main approaches have been extensively investigated in this context, namely sol-gel derived coatings and layer-by-layer assemblies. On the other hand, these approaches can provide treated fabrics with outstanding flame-retardant features. Notwithstanding, according to the composition of the sol-gel recipes and the type of deposited layers in layer-by-layer assemblies, it is possible to design multifunctional (for example, hydrophobic, oil repellent, self-clean, anti-bacterial, electrically conductive, etc.) treatments. Therefore, this review discusses recent advances concerning both sol-gel and layer-by-layer strategies, highlighting current limitations, open challenges, and possible advances. In addition, an attempt has been made to give a brief overview of the works done in this field.
