摘要
以磷钨酸（ＰＴＡ）作电子染料，对聚苯乙烯／聚丙烯酸丁酯（ＰＳ／ＰＢＡ）乳液、乙烯醋酸乙烯（ＥＶＡ）共聚乳液、自交联型丙烯酸酯共聚乳液（ＰＢＡ／ＰＭＭＡ）进行染色，并对染色的条件及方式进行了系统的考查。结果表明，ＰＴＡ能有效地增加这３类乳液核壳结构的质厚差别，使电镜图像清晰、分明。并对染色机理进行了初步探讨。
The core/shell structure of PS/PBA, EVA, PBA/PMMA emulsion was characterized by using phosphotungstic acid(PTA) as electron stain with the help of transmission electron microscope(TEM). The stain condition and method were systematically examined. The results show that the PTA increases effectively difference in mass and thick of the three core/shell emulsion, make TEM image clean and contrast intensifecation. The stain mechanism were crudely discussed.
