| 摘 要： | 以偶联剂γ-(2,3-环氧丙氧)丙基三甲氧基硅烷(KH-560)处理后的超细滑石粉为增强相,聚乳酸(PLA)为基体,制备了超细滑石粉/PLA复合材料。通过傅里叶变换红外光谱(FT-IR)、电子扫描显微镜(SEM)、X射线衍射(XRD)、光学解偏振法、温度-形变曲线及热失重(TG)对复合材料进行了表征。结果表明,KH-560成功地包覆在滑石粉表面,滑石粉表面与PLA基体发生了化学键合,处理后的滑石粉粒子与PLA基体之间形成了良好的界面。适量的滑石粉能够提高PLA基体的结晶速率和结晶度,当滑石粉添加量增大到一定程度,PLA基体的晶格参数和晶体结构会发生变化。当滑石粉分散良好时,复合材料的玻璃化转变温度(Tg)和热稳定性显著提高。

| Abstract: | The super fine talc powder/polylactide(PLA)composites were prepared.The super fine talc powder which modified by coupling agent KH-560 was employed as reinforcement;moreover,the PLA resin was employed as matrix.Fourier transform infrared(FT-IR),scanning electron microscope(SEM),X-ray diffraction(XRD),optical depolarization,temperature-deformation curve,and thermal gravimetric analysis(TG)were employed to characterize the obtained composites.The results showed that,the KH-560 which coated on the surface of t... |
