本論文主要在研究以耐隆納米複合材料摻合不同種類的ABS(丙烯睛-丁二烯-苯乙烯共聚物),討論其剪切粘度與動態模數的變化;並以動態機械熱性質分析(DMTA)測試,觀察添加填充材後材料Tg點的變化及聚摻合系統的tanδ值變化情形。
由於耐隆納米複材與ABS兩者相容性的差異,因此容易在相形態上以SEM圖觀察到主相(matrix)與分散相(dispersion)界面間的交互作用力的不同,對聚摻合物整體的粘度及彈性造成的影響。在粘性方面,我們以在不同剪切速率下的粘度圖,配合加成定律來討論粘度的變化情形;在彈性的變化方面,以流變儀做頻率掃描的實驗得到儲存模數G’對角頻率ω之關係圖,判斷其彈性變化的趨勢。此外,以動態機械熱性質分析(DMTA)的實驗觀察聚摻合物固態的粘彈行為,亦可由圖觀察到摻合系統與純料之間相容性的差異及玻璃轉移溫度(Tg)的變化情形。
實驗結果顯示,耐隆納米複材中的填充材對聚摻合系統的影響隨著分散相ABS濃度的增加而降低,由於ABS本身的的粘度大於耐隆納米複材,又因為相容性上的差異,造成分子間的界面粘著力不良,因此在低組成的摻合系統中所顯現的粘度及彈性較差。另一方面,由動態機械熱性質的分析,可以發現不同比例聚摻合系統的tand幾乎介於兩個純料之間,而添加填充材亦造成PA-6 的 Tg有些微的上昇。

The purpose of the research presented in this paper is to discuss the rheology of Nylon nanocomposite blended with several grades of ABS.
Nylon nanocomposite and ABS are very uncompatible, it is easy to see the micro-phase separation in a matrix using SEM (Scanning Electron Microscopy). To observe the variation of viscosity, the diagrams of viscosity vs. shear rate were used provided with viscosity-additive rule. As for the elasticity, storage modulus G’ vs. angular frequency ω diagrams were obtained from the frequency sweep tests with the rheometer. The results show that the effect of the filler in Nylon nanocomposite on the rheology of the blends goes down as the ABS concentration increases.
In addition, DMTA experiments were performed to investigate the viscoelastic behavior of the polymer blends in the solid state. It is found that the tand of polymetric blending systems is mostly in between that of the two pure materials. The adding filler resulted in the slight increase on PA-6’s Tg.
