| 摘 要： | 采用反相气相色谱技术测定了聚丁二烯橡胶的表面性质。以正己烷、正庚烷、正辛烷、正壬烷作为非极性探针测定其表面色散自由能,以二氯甲烷、三氯甲烷、丙酮、乙酸乙酯、乙醚和四氢呋喃作为极性探针测定其路易斯酸碱常数。经计算得出聚丁二烯橡胶在303、313、323、333和343 K的表面色散自由能分别为47.07、46.46、45.85、45.60和45.09 mJ/m2。结果表明,聚丁二烯橡胶表面色散自由能随着温度的升高呈线性降低,路易斯酸常数Ka为0.34,碱常数Kb为1.77,总酸碱作用能力2.11,该聚合物为弱碱性Lewis两性聚合物材料。此外还计算出聚丁二烯橡胶的酸碱作用吸附自由能（~ΔGsa）和吸附焓（~ΔHsa）。

| Abstract: | Inverse gas chromatography was applied to the characterization of the surface properties of polybutadiene rubber(PBR).Four n-alkanes(C6,C7,C8 and C9-alkanes) were chosen as the apolar probes to characterize the dispersive component of surface free energy.Dichloromethane,trichloromethane,acetone,ethyl acetate,diethylether and tetrahydrofuran were chosen as the polar probes to detect the Lewis acid-base parameters.It was found that the dispersive components of surface free energy were 47.07,46.46,45.85,45.60 ... |
