Publication number: 20130078701Abstract: The present disclosure relates to a device comprising a conductive substrate surface (19), at least one layer of a conductive polymer (14) deposited on the surface (19), a first electrolyte (13) arranged in contact with the conductive polymer layer, and a counter electrode (11), arranged in contact with the first electrolyte (13), such that a potential difference can be applied between the conductive substrate (15) and the counter electrode (11). The conductive polymer (14), in a first state, before applying the potential difference, exhibits a first adhesive capacity, wherein the conductive polymer layer (14) is substantially attached to the conductive substrate surface (19). In a second state, subsequent to application of the potential difference, the conductive polymer (14), exhibits a second adhesive capacity, such that at least a portion of the conductive polymer layer (14) is substantially released from the conductive substrate surface (19).Type: ApplicationFiled: April 6, 2010Publication date: March 28, 2013Applicant: OBOE IPR ABInventors: Kristin Persson, Roger Karlsson, Magnus Berggren, Peter Konradsson, Edwin Jager, Agneta Richter-Dahlfors, Karl Svennersten

Patent number: 8400750Abstract: A particle charger with sheath air flow for enhancing charging efficiency includes a housing and a discharge wire. The housing has a charging chamber for accommodating the discharge wire, a particle inlet, a sheath air inlet, an outlet and an accelerating channel. A clean sheath air is guided through the sheath air inlet into the charging chamber to surround charged particles, reducing deposition of charged particles on the inside wall of the housing. A relatively small annular gap of accelerating channel accelerates the charged particles to exit the particle charger, and therefore minimized the particle electrostatic loss due to depositing on the inner surface of the housing. Additionally, uncharged particles approach the discharge wire axially, and charged particles move away radially. It is helpful for the charged particles to diffuse rapidly and uniformly, thereby enhancing the charging efficiency.Type: GrantFiled: December 29, 2009Date of Patent: March 19, 2013Assignee: National Chiao Tung UniversityInventors: Chuen-Jinn Tsai, Lin Guan-Yu, Chen Hui-Lin
