Microporosity in bis-glycidyl methacrylate films. 1980

B Williams, and J A von Fraunhofer

The existence of hitherto unsuspected micropores in fissure sealant films (bis-glycidyl methacrylate resin films) has been demonstrated by means of scanning electron microscopy. Immersion of specimens in various ionic solutions showed that the defects in the surface of the resin film tended to become filled with the passage of time.

UI	MeSH Term	Description	Entries
D008689	Methacrylates	Acrylic acids or acrylates which are substituted in the C-2 position with a methyl group.	Methacrylate
D008855	Microscopy, Electron, Scanning	Microscopy in which the object is examined directly by an electron beam scanning the specimen point-by-point. The image is constructed by detecting the products of specimen interactions that are projected above the plane of the sample, such as backscattered electrons. Although SCANNING TRANSMISSION ELECTRON MICROSCOPY also scans the specimen point by point with the electron beam, the image is constructed by detecting the electrons, or their interaction products that are transmitted through the sample plane, so that is a form of TRANSMISSION ELECTRON MICROSCOPY.
