Abstract

Many commonly used polymers are inherently flammable. Manufacturers have been able to make polymers more flame-resistant by incorporating additives in polymer matrices. Current testing methods of these materials are destructive. As a result, there is a lack of data that can characterize the long-term effects of thermal exposure on these materials. This study presents single-sided NMR as an alternative technique to characterize the physical properties of these materials before and after thermal exposure. From single-sided NMR, this study finds that it is possible to characterize the molecular behavior of flame-resistant polymers and that additives cause no significant physical change to the polymer matrix. This study also finds that single-sided NMR data can detect changes in the molecular behavior of these materials. This research emphasizes the use of single-sided NMR to study flame-resistant polymers and may prompt further study in fields such as firefighter health and safety.
