中文摘要: |
利用扫描探针显微镜(SPM)的DFM模式观察苯乙烯-丁二烯-苯乙烯嵌段共聚物(SBS)和炭黑/SBS混合物的微观形貌。结果表明:不同浓度的SBS溶液的微观形貌差异较大;炭黑/SBS混合物的分离物成“手镯”环状结构,尺寸为100 nm左右,与炭黑相连物质的长度为200~300 nm,横向直径约为100 nm,与SBS单体的尺寸吻合,可初步判定该结构为炭黑/SBS结合橡胶。 |
英文摘要: |
The microstructures of SBS and carbon black/SBS mixture were studied by DFM pattern of scanning probe microscopy (SPM).The results showed that,the microstructures of SBS solution in different concentration were significantly different.The separated substances of carbon black/SBS mixture appeared “bracelets” ring structure,and the size was about 100 nm.The length of the substance connected with carbon black was 200~300 nm,and the transverse diameter was nearly 100 nm,which was initially determined as carbon black/SBS bound rubber. |
