Surface modified nozzle plate |
摘要 |
The invention relates to an ink jet printer nozzle plate containing nozzle holes and having a durable non-wettable layer on at least one surface thereof. The nozzle plate includes a polyimide material and the non-wettable layer contains a derivative of an amine-terminated silane compound, the amine-terminated silane compound derivative being covalently bound to the polyimide material of the nozzle plate. The layer also contains a derivative of a polydialkylsiloxane compound having a number average molecular weight ranging from about 400 to about 150,000 and an end group reactive with the amine-terminated silane compound derivative. The polydialkylsiloxane compound derivative is bound to the amine-terminated silane compound derivative by a condensation reaction to provide the durable non-wettable layer on the surface of the nozzle plate. Because of covalently bonding the silane and polydialkylsiloxane materials to the polyimide, the non-wettable layer remains substantially durable throughout the life of a printhead containing the nozzle plate.
