中文摘要：

本文通过自制改性剂对聚氯代对二甲苯薄膜表面进行改性，两片改性膜采用单搭接方式用普通氟碳树脂粘接。通过剪切强度测试和水接触角测量研究了不同改性剂浓度的改性效果，用原子力显微镜（AFM）和扫描电子显微镜（TEM）研究了改性前后薄膜的表面形态，用衰减全反射傅立叶变换红外光谱（ATR-FTIR）分析了改性前后薄膜中各基团的变化、X射线衍射仪（XRD）研究了反应前后薄膜的物相变化并通过其物相分析功能确定反应的产物。结果表明：自制改性剂具有较高的反应活性，在室温条件下当聚氯代对二甲苯薄膜与改性剂接触时快速发生反应，反应的最终结果是改性剂中亲核试剂破坏苯环上的C-Cl键，聚氯代对二甲苯薄膜中苯环上的Cl原子与改性试剂中的钠离子形成的氯化钠附着在膜的表面；改性剂浓度为1．5mol／L时处理效果最好，聚氯代对二甲苯薄膜表面与去离子水的接触角从未改性时的96．49度降到67．5度，改性后的聚氯代对二甲苯薄膜表面能由14．335mJ／m2提高到34．798mJ／m2；剪切强度值由改性前的150．4KPa提高到212．8KPa。

英文摘要：

In the paper, the surface of the PC film is modified with the solution of sodium-naphthalence, and two pieces of the modified films are fastened together by the combination of the ordinary fluorocarbon resin and the N75 hardener. The mod- ification effects of the adherent films under different experimental conditions--modification solutions with different concentra- tions and different reaction times are tested by the shearing strength test and the droplet contact angle measurement. The chemical compositions and the topographys of the films before and after the modification are characterized with attenuated total reflectance infrared spectroscopy （ATR-FTIR）, X-ray fluorescence spectroscopy （XRF） and scanning electron microscopy （SEM）. Moveover, the surface topologys, the crystalline structures and the reaction productions of the films before and after the modification are tested by the atom force microscopy （AFM）, the scanning electron microscopy （SEM） and the x-ray dif- fraction （XRD）. The results showed that the components of the PC films was changed by the the solution of sodium-naphtha- lene with tetrahydrofuran （THF）, the chorine content was decreased, the surface color of the films was changed to yellow, and the surface roughness, reached a suitable degree, and the wettility of the PC films was improved. Besides, the best effect of the modification was achieved when the concentration of the modifier was 1.5mol/L and the reaction time was 10 minutes. Under that condition, the the droplet contact angle decreased from 96.49 degrees to 67. 5 degrees, the surface energy of the film was increased from 14. 335 mJ/m2 to 34. 798 mJ/m2, and the shearing tension of it was reached over 212. 8KPa.
