実験手順

A solution of polyamic acid was prepared at room temperature by combining 1.215 grams of 6FDA, 2.395 grams of BPDA, 3.476 grams of TFMB and 28.7 grams of NMP with good mixing. The amic acid solution was diluted to 10% solids, then cast on a silicon wafer by spin coating, and imidized by a heat treatment up to a maximum temperature of 300° C. to produce a coating having a thickness of 1.9 microns. The refractive index was determined in the same manner as in Example 1 and is reported in Table I.
