1.概要通常称为电解质的材料中有无机的和有机的两种,为数很多。这些材料特别引人注意的物理性质有介电常数、介电损耗、频率变化引起介电常数的色散等。而一般高分子材料的相对介电常数为1～10,介电损耗为10量级。常用薄膜状材料作为电容器材料,这是众所周知的。然而,到本世纪四十年代中期,发现天然高分子材料具有压电性,其后,发现 1. General There are two types of inorganic and organic materials commonly referred to as electrolytes, a large number. The special physical properties of these materials are the dielectric constant, the dielectric loss, the dispersion of the dielectric constant caused by the frequency change, and the like. The relative dielectric constant of general polymer materials is 1 to 10, the dielectric loss of 10 orders of magnitude. It is well-known that film-like materials are commonly used as capacitor materials. However, by the mid-1940s, natural polymer materials were found to have piezoelectricity. Later, it was found
