Properties of foam coated surface of polyimide/PTFE composite filtering material
Source abstract
Abstract
The surface foam coating of polyimide(P84)fiber/polytetrafluoroethylene(PTFE) fiber composite filtering material was conducted with PTFE emulsion,and the effect of coating on the structure and properties of composite filtering material was studied.X-ray diffraction and scanning electron microscopy analysis showed that a lay of compact and porous coating of PTFE formed on the surface of the material after coating treatment.The results of differential scanning calorimetry and thermogravimetry indicated that P84/PTFE filtering material after coating still kept its good thermal stability.The research of thermal shrinkage and chemical resistance properties of the coated P84/PTFE composite filtering material proved that its dimensional stability under high temperature and resistance to acid and alkali were improved.
