Fabrication of cross-linked polymer shells for inertial confinement fusion experiments

Abstract

For inertial confinement fusion experiments, a copolymer of acrylonitrile and styrene (AS) shell overcoated with a cross-linked polyvinyl alcohol (PVA) has been fabricated in order to obtain good gas-barrier properties and resistance to beta decay of tritium. The fabrication method is based on the emulsion method using the interfacial poly-condensation reaction between water and oil phases. Cross-linked PVA with a thickness of 5 μm has been successfully overcoated on an AS shell. The surface roughness has been estimated using an atomic force microscope to be 0.5 nm (root mean square).

“…And it can similarly characterize the sample in depth. (iv) Other techniques, such as mass spectroscopy, thermogravimetric analysis, atomic absorption, and atomic force microscope are discussed in Brundle et al (1992), Schultz et al (1999), and Kubo et al (1997), as well as in numerous other publications.…”
