0.3%GO涂层,通过扫描电子显微镜来表征复合涂层的断截面形貌。样品制备步骤:将制备的涂料涂覆在PET基底膜上,待固化后将涂层剥离下来,然后通过液氮将其脆断,并将样品表面喷金。
0.3%GO coating, characterized by scanning electron microscopy to characterize the cross-sectional topography of composite coatings.Sample preparation step: the prepared paint is coated on a PET substrate film, the coating is peeled off after curing, and then embrittled by liquid nitrogen, and the sample surface is sprayed with gold.
