Simultaneous deposition of submicron aerosols onto both surfaces of a plate substrate by electrostatic forces

We demonstrate one-step deposition of submicrometer-sized particles suspended in the gas-phase onto a plate type substrate using an electrostatic-assisted spray system. The particles were deposited on plate-type metallic surfaces, on both front and rear sides of the substrate. This “both-side” deposition can be ascribed to deflection of charged particles in the front side, and then drifting of the particles around the rear side. 気相中に浮遊した帯電微粒子の板状基板上への堆積を実証した。微粒子は基板の表裏両面に堆積した。この 「両面」 の堆積は、表面での荷電粒子の偏向、およびその後の裏面の周りでの粒子のドリフトに帰する。
