This paper reviewed the types, preparation methods and research status of single polymer composites （SPCs）, highlighting the merits and demerits of related processes. Besides, the further developments of SPCs were prospected. It pointed out that the poly-sulfonamide （PSA） based single polymer composite had excellent performance in thermal stability and flame resistance since the glass transition temperature was over 300 ℃ and the decomposition temperature was higher than 420 ℃. Therefore, the PSA based SPCs were expected to become a new generation of aerospace materials. The mechanical performance of SPCs were improved when the materials had been nano or micro-sized under the help of electrostatic spinning. SPCs＇ application in aerospace, automotive and other fields would be the key point of following research, and it also has a significant application prospect in biomaterials.
