R. Schwodiauer et al., CHARGE STABILITY OF PULSED-LASER DEPOSITED POLYTETRAFLUOROETHYLENE FILM ELECTRETS, Applied physics letters, 73(20), 1998, pp. 2941-2943
Pulsed-laser deposited (PLD) polytetrafluoroethylene (Teflon-PTFE) fil
ms from press-sintered targets are found to be highly crystalline, wit
h spherulite sizes adjustable over more than one order of magnitude by
suitable thermal annealing. Films with large spherulites show an exce
llent charge stability, comparable and even superior to commercially a
vailable Teflon-PTFE foils. PLD-PTFE enlarges the family of Teflon mat
erials and may thus become interesting for potential miniaturized elec
tret devices. (C) 1998 American Institute of Physics. [S0003-6951(98)0
