摘　　要：将葡萄籽提取物原花青素(proanthocyanidin,PA)分别用乙醇、丙酮、蒸馏水配制成不同浓度的预处理剂,利用傅里叶红外光谱测试PA预处理对Single Bond 2和Prime&Bond NT两种全酸蚀粘接系统双键转化率的影响。结果发现不同溶剂、浓度的PA预处理剂组2种全酸蚀粘接剂的双键转化率与阴性对照组均无统计学差异(P>0.05)。提示原花青素预处理对全酸蚀粘接系统固化性能无显著影响。Proanthocyanidin（PA） was used to prepare preconditioners in alcohol, acetone and distilled water respectively. The effect of PA pretreatment on the degree of conversion of single Bond 2 and Prime ＆ Bond NT was tested by Fourier transform infrared spectroscopy. No statistical difference was found in the degree of conversion among groups with different pretreatments （ P 〉 0.05 ）. PA pretreatment has no adverse effects on the curing behaviors of the tested adhesive systems.
