Description
本実施例では、ポリマーセラミック前駆体としてポリシラザン(PSZ)を使用し、ブロック共重合体としてポリブタジエン−ブロック−ポリエチレンオキシド(PB−b−PEO)を使用してC/SiCN(−O)の規則性セラミック複合材を製造した。
本実施例では、ポリカルボシランをポリブタジエンと非相溶性のものからポリブタジエンと相溶性のものへと変えるため、ポリカルボシランの極性を変化させた。
本実施例では、ポリマーセラミック前駆体としてポリシラザン(PSZ)及び実施例2で製造した改質ポリカルボシラン(m−PCS)を使用し、ブロック共重合体としてポリブタジエン−ブロック−ポリエチレンオキシド(PB−b−PEO)を使用して、2種類のセラミック組成物を含む規則複合材を製造した。
本実施例では、ポリマーセラミック前駆体としてポリシラザン(PSZ)及びポリ(ジペンチルアミノボラジレン)(DPBZ)を使用し、ブロック共重合体としてポリブタジエン−ブロック−ポリエチレンオキシド(PB−b−PEO)を使用して、2種類のセラミック組成物を含む複合形態の規則複合材を製造した。複合構造体は、マクロ相分離領域に2つの長さスケールが異なる規則構造を含んでいた。
本実施例では、ポリマーセラミック前駆体としてポリシラザン(PSZ)及びポリ(ジペンチルアミノボラジレン)(DPBZ)を使用し、ブロック共重合体としてポリブタジエン−ブロック−ポリエチレンオキシド(PB−b−PEO)を使用して、2種類のセラミック組成物を含む規則複合材を製造した。本実施例では、PSZとDPBZとの反応を軽減することため、トリエチルアミン(TEA)を添加してDPBZを錯化して一様なドメインサイズを有する規則構造を得た。
本実施例では、ポリマーセラミック前駆体としてポリシラザン(PSZ)及びアルキルアミノボラジン(AABZ)を使用し、ブロック共重合体としてポリブタジエン−ブロック−ポリエチレンオキシド(PB−b−PEO)を使用して、2種類のセラミック組成物を含む規則複合材を製造した。この実施例で使用したポリマーAABZは、分子前駆体を不活性雰囲気下で130℃で24時間加熱した後180℃で36時間加熱することによって得た。
