摘要
用ＨＣｌ、ＮａＯＨ处理阴离子型聚氨酯乳液，使之处于酸碱条件下，并用磷钨酸（ＰＴＡ）作电子染色，用透射电镜（ＴＥＭ）观察染色后的乳胶粒，获得了聚氨酯乳胶粒在酸碱条件下不同的形态结构信息，并与未作处理的进行比较，分析探讨了酸碱条件对乳胶粒形态结构造成影响的原因，并对ＰＴＡ的染色效果进行了分析和评价。
Afetr treated with HCl or NaOH,the anionic PU emulsion could be dyed with PTA on different pH conditions.The morphology structure information of dyed latex particles on corresponding pH conditions was obtained by using TEM and compared with that of nontreated latex particle.It was analyzed how pH condition influenced the morphology and structure of the latex particles.Dyeing effect of the PTA was also discussed and evaluated.
