Polar ultrathin film
专利汇可以提供Polar ultrathin film专利检索，专利查询，专利分析的服务。并且PURPOSE: To obtain the subject stable ultrathin film, molecularly polarized therein and excellent in piezoelectric, pyroelectric effects, etc., by forming monomolecular films using a compound in which a specific functional part is introduced into at least either of hydrophobic groups in two kinds of specified compounds having the hydrophobic groups and alternately cumulating the formed monomolecular films.
CONSTITUTION: The objective ultrathin film obtained by introducing a functional part having dipole moment into at least either of hydrophobic groups in (A) a compound [e.g. expressed by the formula R
1 COOH (R
1 is long-chain aliphatic, alicyclic or aromatic hydrophobic group)] having acidic group and the hydrophobic group and (B) a compound [e.g. expressed by the formula R
2 NH
2 (R
2 is same as R
1 )] having basic group and the hydrophobic group, using the resultant compound expressed by the formula, etc., forming monomolecular films according to the Langmuir-Blodgett(LB) method utilizing acid-base bonds and alternately cumulating the formed monomolecular films.
