Abstract: A screening panel 10 comprises a peripheral frame 12 consisting of a pair of mutually laterally spaced side members 14, 16, which are integral with a pair of mutually axially spaced end members 18, 20. The side members 14, 16 and end members 18, 20 define corners of the panel 22.1, 22.2, 22.3 and 22.4 and the peripheral frame 12 where they meet. A plurality of mutually spaced ribs 15 extend across the periphery of the panel 10 to define a screening surface. The side members and end members are rectangular in cross-section, thereby defining substantially flat upper peripheral surfaces 12.1, outer peripheral surface 12.2 and lower peripheral surface 12.3 of the peripheral frame 12 and thus also the panel 10. The panel 10 includes locating recesses 24 provided at or near to the corners 22.1, 22.2, 22.3 and 22.4 of the panel 10. The panel 10 also has separate securing recesses in the form of semi-circular grooves 30 formed in the lower surface 12.

Abstract: A method for modifying an ePTFE surface by plasma immersion ion implantation includes the steps of providing an ePTFE material in a chamber suitable for plasma treatment; providing a continuous low energy plasma discharge onto the sample; and applying negative high voltage pulses of short duration to form a high energy ion flux from the plasma discharge to generate ions which form free radials on the surface of the ePTFE material without changing the molecular and/or physical structure below the surface to define a modified ePTFE surface. The step of applying the high voltage pulses modifies the surface of the ePTFE without destroying the node and fibril structure of the ePTFE, even when the step of applying the high voltage pulses etches and/or carburizes the surface of the ePTFE. The modified surface may have a depth of about 30 nm to about 500 nm. The ions are dosed onto the ePTFE sample at concentrations or doses from about 1013 ions/cm2 to about 1016 ions/cm2.
