使用原子力显微镜（AFM）纳米压痕，我们已经测量了各种聚合物的力学性能：低密度聚乙烯，聚乙烯醇，高密度聚乙烯，高分子量聚乙烯，聚氯乙烯，聚碳酸酯，尼龙6，聚（甲基丙烯酸甲酯），聚苯乙烯和聚丙烯酸。通过AFM的力-压痕曲线和面积-深度曲线，获得了聚合物的硬度和杨氏模量。对比分析表明，两种方法得到的结果几乎一致，且具有自洽性。(C)2009爱思唯尔有限公司保留所有权利。
Using atomic force microscopy (AFM) nanoindentation, we have measured the mechanical properties of various polymers: low density polyethylene, polyvinyl alcohol, high density polyethylene, ultrahigh molecular weight polyethylene, polyvinyl chloride, polycarbonate, Nylon 6, poly(methyl methacrylate), polystyrene and polyacrylic acid. The hardness and Young's modulus of the polymers were obtained by AFM through both the force-indentation and area-depth curves. Our comparative analysis shows that the two methods give almost identical results with self-consistency. (C) 2009 Elsevier Ltd. All rights reserved.
