用氨(NH3)等离子体对无定形碳片(AC)表面进行改性，以在AC表面形成伯氨基。经NH3等离子体改性后，AC片材表面同时形成含氮和含氧基团，水与改性AC表面的接触角由76°降至°-56°。在低射频功率(5-10W)下工作的NH3等离子体比在高功率工作的NH3等离子体更有利于伯氨基的形成。NH_3等离子体的射频功率大小对伯氨基浓度有很大影响。在10W下工作的NH3等离子体有利于在AC片表面形成伯氨基，其浓度为1.3-1.4N(氨基)原子/100C原子。
Amorphous carbon (AC) sheet surfaces were modified with ammonia (NH3) plasma in order to form primary amino groups on AC surfaces. The NH3plasma modification formed both nitrogen- and oxygen-containing groups on the AC sheet surfaces, and the contact angle of water against the modified AC surfaces decreased from 76° to 64°–56°. The formation of primary amino groups preferred NH3plasma operated at a low rf power (5–10W) to that at a high power. The concentration of primary amino groups was strongly influenced by how much rf power the NH3plasma was operated. The NH3plasma operated at 10W was a preferable condition for the formation of primary amino groups on the AC sheet surfaces, and their concentration was 1.3–1.4 N(amino)-atoms/100 C-atoms.
