Title:
【発明の名称】エレクトレットを均一に分布させた極微孔性材料
Document Type and Number:
Japanese Patent JP3361810
Kind Code:
B2
Abstract:
A poromeric material for maintaining an electrostatic charge is provided, the material including a matrix of fibers, a polymeric binder for binding the matrix, and electrets present substantially uniformly throughout the poromeric material. Also provided are methods for making the poromeric material. In one embodiment, a polymeric binder mixture having electrets substantially uniformly contained therein is formed. The matrix of fibers is impregnated with the mixture and cured, whereby the electrets are substantially uniformly distributed throughout the matrix to produce the electrostatic poromeric material. In an alternative embodiment, the electrets are contained in the fibers of the matrix. The poromeric material may be used to encase a core to form a roller, for example, a hickey-removing roller.
