Abstract

Suspension made of Fe(SO), polyvinyl alcohol and carbon nanotubes is placed in electric field to separate charges. Charges remain separated as suspension solidifies, forming composite films with cations and anions enriched at opposite sides. Polarized films behave as junction diodes with forward current and threshold voltage found to be 10-10 A and 2.4-2.6 V at ± 5 V. Rectification is preserved in strained composite films.

摘要

由硫酸铁、聚乙烯醇和碳纳米管制成的悬浮液置于电场中以分离电荷。当悬浮液凝固时，电荷保持分离状态，形成复合膜，阳离子和阴离子在相对的两侧富集。极化膜表现为结型二极管，在±5V时，正向电流和阈值电压分别为10⁻¹⁰A和2.4 - 2.6V。在应变复合膜中整流作用得以保留。
