| 中文摘要 | 本研究係採用二種聚氨基甲酸酯(PU)彈性體與各種不同比率的聚(4,4'--二苯磺 醯基對苯醯胺)(PSA),藉物理摻合法備製8種PU/PSA聚參合體,觀察聚摻合體表面形態, 並作機械性質探討(包括應力--應變測試和應力鬆弛測試)。楊氏係數E, Mooney-Rivlin關 係式中之彈性參數C1和C2及鬆弛模E(10秒)和E(100秒)等數據,由實驗求得,以探討聚 摻合體內含有半剛直性PSA分子對摻合體機械行為之影響。結果發現PU/PSA聚摻合體仍具有 良好的彈性性質,縱使PU/PSA聚摻合體呈現一分散相構造,在低PSA含量(100wt%以下), PU/PSA聚摻合體改善了傳統PU的應力緩和性質。 |
| 英文摘要 | Two polyurethane(PU) elastomers were blended physically with various ratios of ploy (4,4'-diphenylsulfone terephthalamide)(PSA) to form eight PU/PSA polyblends in order to modifty their mechanical properties. Stress-stain and stress-relaxation behavior of PU/PSA polyblends were studied. The measured values of Young's modulus E, Mooney-Rivlin elastic parameters C1 and C2, relaxation moduli E (10 sec) and E (100 sec), as well as relaxation speed (Vr) were used to estimate the effect of semi-rigid PSA molecules on the mechanical behavior of polyblends. It was found that PU/PSA polyblends were shown a dispersed phase structure. Using lower amount of PSA molecules (below 10 wt% PSA), PU/PSA polyblends improved their stress-relaxation properties. |
