With the development of economy and technology, the demand of safer and more stable packaging materials for electronic devices has increased. Traditional polyimide (PI) base materials are extensively used due to their excellent mechanical and heat-resistant properties. In this study, a novel fluorinated polyimide (FPI) porous composite film was developed by introducing fluorine groups and a porous structure into polyimide, along with adding the flame retardant 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO). Experimental results demonstrate that under 80%RH of ambient humidity and 5% of DOPO mass fraction, the new FPI porous composite film exhibits uniform and regularly distributed pore size, excellent mechanical properties, and lower water absorption. The incorporation of flame retardant DOPO forms a protective phosphorus-containing layer on the film surface, which significantly improves the flame retardancy and hydrophobic properties of film. This research provides a new material with enhanced safety for the packaging of electronic devices, which is expected to play a crucial role in improving the stability and safety of electronic equipment.
