应用ＬＢ成膜技术，将聚酰胺酸和十六胺在溶剂中混合制成单分子膜，并沉积到新解理的高取向热解石黑衬底上，然后用原子力显微镜（ＡＦＭ）现测其微结构．现察到聚酰亚胺聚合链分子在空间排列的各种构象，经定标测定：实验结构参数与用分子动力学在理论上的估算值相吻合，证明了所观测到的ＡＦＭ图象的真实性。 Using LB film forming technology, the polyamic acid and hexadecylamine are mixed in a solvent to form a monomolecular film and deposited onto the newly cleaved highly oriented pyrolytic stone black substrate, and then measured by atomic force microscopy (AFM) Its microstructure. It is observed that the polyimide polymer chain molecules arranged in various spatial conformations, determined by calibration: the experimental structure parameters and molecular dynamics in the theoretical estimates coincide, to prove the observed AFM image Authenticity.
