Abstract

Measurements are reported of the contact angles of benzene-derived carbon fibers with de-ionized water, aminopropyltriethoxy silane and du Pont 5878 polyimide solutions. Both pristine fibers and fibers implanted with 5 multiplied by 10**1**2 cm** minus **2 and 1 multiplied by 10**1**5 cm** minus **2 fluences of **3**1P ions were investigated. Such implantation was observed to decrease the contact angle in all three solutions. The ion implantation had no significant effect on tensile strength, but did result in increased structural disorder (as reflected in the width of the main wide angle X-ray diffraction peak) and increased surface roughness. The increased disorder and roughness are believed to be principally responsible for the observed change in wetting angle. This study is relevant to graphite-fiber-reinforced materials for microelectronics.
