Abstract
A microwave-assisted surface grafting of polyacrylamide (PAAm) enabling durable flame resistance on nylon-6,6 fabric is presented. The PAAm grafted nylon-6,6 (PAAm-g-nylon-6,6) fabric is characterized by FTIR and H NMR. Self-extinguishing nylon-6,6 fabric with a char length of 7.7 cm and after-flame of 2 s in the ASTM D6413 vertical flame test is achieved with 7–8% PAAm grafting. The melt/flame dripping behavior of neat nylon-6,6 is also significantly suppressed by PAAm through enhanced char formation and a gas dilution mechanism, as observed in thermogravimetric analysis. The laundry test followed by the vertical flame test and heat release characterization of PAAm-g-nylon-6,6 suggests that the robust grafting of PAAm provided durable flame resistance to nylon-6,6 fabric. The PAAm-g-nylon-6,6 exhibits a char length of 6.1 cm and an afterflame of 0 s after 20 standard laundry cycles.
期刊介绍：
ACS Applied Polymer Materials is an interdisciplinary journal publishing original research covering all aspects of engineering, chemistry, physics, and biology relevant to applications of polymers.
The journal is devoted to reports of new and original experimental and theoretical research of an applied nature that integrates fundamental knowledge in the areas of materials, engineering, physics, bioscience, polymer science and chemistry into important polymer applications. The journal is specifically interested in work that addresses relationships among structure, processing, morphology, chemistry, properties, and function as well as work that provide insights into mechanisms critical to the performance of the polymer for applications.
