EXCITING ARTIFICIAL FILM FOR BIO-ELEMENT

摘要

PURPOSE:To realize the title artificial film capable of self-exciting oscillation for a short time period meeting the requirements for reduced or cancelled external pressure by a method wherein the said film is composed of a porous film on which mixed lipid comprising dioleilphosphate and specific amount of cholesterol is adsorbed. CONSTITUTION:The title artificial film is composed of dioleilphosphate represented by the structural formula I and cholesterol represented by the structural formula II as well as a porous film on which mixed lipid in additive content exceeding 1wt.% and not exceeding 40w.t% is adsorbed. That is, the said film is composed of the porous film on which the mixed lipid comprising dioleilphosphate and cholesterol is adsorbed. Through these procedures, the title exciting artificial film for bio-element capable of notably decreasing the external pressure required for self-exciting oscillation for a short time period compared with that of any conventional films can be formed.
