Polyimide (PI) matrix nano composite films have been studied extensively and been taken as field-grading materials in aircraft, flexible circuit boards, new energy batteries and so on. In present paper, the composite films doped with different weight content of fumed Al2O3 were prepared by in-situ polymerization (the contents of Al2O3 in the composite films are 5%, 10%, 15%, 20%). TEM and SAXS were...
This paper employs the SAXS technique to study the microstructure evolution of nano Al2O3/low-density polyethylene (LDPE) composite film during temperature increase and decrease (including interfacial layer thickness, mass fractal and surface fractal), and discusses the deformation memory effect (DME) mechanism. Compared with the case of pure LDPE, there are some new phenomena observed in the Al2O...
