Abstract:
1. An atmospheric-pressure double-plasma graft polymerization apparatus comprising, sequentially arranged: a workbench comprising an electrically insulating board provided thereon; an initial roller device of a roll-to-roll device comprising a roll of initial substrate, a base provided on the electrically insulating board of the workbench, and a reel provided on the base; an atmospheric-pressure plasma activation device connected to the initial roller of the roll-to-roll device and comprising the substrate, a plasma working gas, an electrode assembly, a first uniform gas entrance device and a first uniform gas exit device wherein flow rates of working gas are similar in different positions along the first uniform gas entrance device and the first uniform gas exit device; a peroxide formation device connected to the atmospheric-pressure plasma activation device and comprising plasma activated substrate, an entrance roller, an exit roller and an extended air-exposure time upper roller with adjustable height; a coating and grafting device connected to the peroxide formation device and comprising peroxide-formed substrate, a graft solution, a graft solution tank, an entrance roller, two lower rollers, a pair of thinning rollers, an upper roller and an exit roller; a drying device connected to the coating and grafting device and comprising initially grafted substrate with the graft solution coated on two sides of the peroxide-formed substrate, a heating chamber, an thermally insulating layer, two flexible heating plates and a temperature sensor attached to two parallel metal plates, an upper entrance roller, an extended heating-time entrance roller and an exit roller; an atmospheric-pressure graft polymerization and curing device connected to the drying device and comprising initially grafted substrate with the graft solution coated on the substrate and dried to 90 to 95% as graft polymerization and curing agent, a plasma working gas, an electrode assembly, a second uniform gas entrance device and a second uniform gas exit device wherein flow rates of working gas are similar in different positions along the second uniform gas entrance device and the second uniform gas exit device; a curing device connected to the graft polymerization and curing device and comprising graft polymerized and cured substrate, a heating chamber, a thermally insulating layer, two flexible heating plates and a temperature sensor attached to two parallel metal plates, an upper entrance roller, an extended heating-time entrance roller and an exit roller; and a final roller of a roll-to-roll device connected to the curing device and comprising a roll of cured substrate, a base provided on the workbench and a reel provided on the base.
