本研究采用傅里叶变换红外/衰减全反射（FTIR/ATR）分析法，评价了五种溶剂挥发方法对九种单瓶粘合剂体系转化度（DC）的影响。测试了九种粘合剂：Adper Single Bond 2（SB）、Adper Easy One（EO）、One Up Bond F Plus（OUP）、One Coat Bond SL（OC）、XP Bond（RP）、安巴尔（AM）、Natural Bond（NB）、GO和Stae。将粘合剂体系施加到硒化锌丸粒上，并且1）在没有溶剂挥发的情况下固化，2）在固化之前静置10秒，3）在固化之前静置60秒，4）在固化之前用空气流风干10秒，以及5）在固化之前用空气流风干60秒。获得FTIR/ATR光谱，并通过比较光活化10秒之前和之后的脂族键/参比峰来计算DC（FlashLite 1401）。每种材料的DC均值采用单因素方差分析和事后Tukey检验进行分析（p
This study evaluated the effect of five methods of solvent volatilization on the degree of conversion (DC) of nine one-bottle adhesive systems using Fourier transform infrared/attenuated total reflectance (FTIR/ATR) analysis. Nine adhesives were tested: Adper Single Bond 2 (SB), Adper Easy One (EO), One Up Bond F Plus (OUP), One Coat Bond SL (OC), XP Bond (RP), Ambar (AM), Natural Bond (NB), GO, and Stae. The adhesive systems were applied to a zinc-selenide pellet and 1) cured without solvent volatilization, 2) left undisturbed for 10 seconds before curing, 3) left undisturbed for 60 seconds before curing, 4) air-dried with an air stream for 10 seconds before curing, and 5) air-dried with an air stream for 60 seconds before curing. FTIR/ATR spectra were obtained, and the DC was calculated by comparing the aliphatic bonds/reference peaks before and after light activation for 10 seconds (FlashLite 1401). The DC means of each material were analyzed by one-way analysis of variance and post hoc Tukey test (p
