Notes:
The total end-point dose (i.e., the electron irradiation dose necessary for complete destruction of the crystal lattice) was measured at 120 kV and room temperature for poly(ethylene oxide), polyethylene, isotactic polystyrene (i-PS), poly(p-xylylene), ramie and bacterial cellulose, and lobster chitin. On the basis of the results obtained, the possibility of lattice imaging of polymer crystals is discussed. As reported in an earlier preliminary paper, 1.1- and 0.55-nm lattice fringes were resolved in i-PS single crystals by using a conventional transmission electron microscope equipped with a device for low-dose imaging. In this paper, the detailed procedure for lattice imaging of i-PS crystals is described and various features of the lattice images are discussed.
