采用丝网印刷法在氧化铝基底上制备了La0.6Sr0.4FeO3薄膜.利用扫描电镜、流变仪、X射线衍射仪、红外光谱仪、四探针和划痕仪研究了有机载体配比对薄膜成膜效果、浆料粘度、电阻均匀性和与基底结合强度等的影响.结果表明,松油醇和乙基纤维素(EC)的配比对浆料成膜效果影响显著,加入60%松油醇时,薄膜较为平整,但裂纹较多.当加入乙基纤维素(EC)2%~3%时,浆料粘度提高为0.23 Pa.s和0.55 Pa.s,最有利于薄膜印刷,且膜裂纹少,膜层均匀连续;烧结后的薄膜为单一的钙钛矿相,且Fe-O键比粉体的结合强;并且薄膜方阻均匀,与基底的结合力强.因此松油醇含量60%、EC加入量2% ~3%的铁酸锶镧浆料最适于丝网印刷成膜.
