Abstract
The present invention relates to a method for preparing polymer film, comprising the following steps: i) forming at least one polymer as a first membrane by electrospinning; ii) forming a first mixture by dispersing at least one mid-infrared radiation reflective material into a first liquid; iii) filtering said first mixture, wherein said first membrane is used as a filter membrane, thereby depositing said at least one mid-infrared radiation reflective material on said first membrane to form a second membrane, and iv) drying said second membrane to form a third membrane; characterized in that, said at least one polymer is selected from polyvinylidene fluoride and/or polyurethane.
