Molecular composite is a kind of rigid/flexible polymeric composite where polymer components are dispersed at the molecular level. Molecular composite extends the concept of fiber-based macro-composite to the molecular level. It has the advantages of high strength and high modulus. As a category of high-performance composites

the research and development of molecular composites is of great significance to the development and innovation of high-performance composites. In this paper

the composition

preparation methods and the compatibility control of polymer pairs in molecular composite were introduced. Moreover

the details of the present research of molecular composite were well described. Finally

some problems deserving further research of molecular composites were presented and the development prospect of molecular composites was prospected.
