我们对聚合物(聚苯乙烯(PS)、聚甲基丙烯酸甲酯(PMMA))渗透到三维定向碳纳米管阵列的自由空隙中的行为进行了实验和理论研究。采用模板辅助非催化CVD法制备了三维定向的碳纳米管结构。利用红外光谱、拉曼光谱等显微技术对浸渍碳纳米管/聚合物复合材料进行了表征。用小角X射线散射(SAXS)研究了聚合物渗透到定向排列的碳纳米管阵列后的结构演化和聚合物约束。利用自洽场理论(SCFT)和基于键涨落模型的蒙特卡罗模拟，建立了一个理论模型来理解和预测这些聚合物在定向碳纳米管阵列中可能的限制效应。
We present experimental and theoretical studies on the infiltration of polymers (polystyrene (PS), polymethylmethacrylate (PMMA)) into the free interstices of 3D aligned carbon nanotube arrays. The 3D aligned CNT structures were prepared by a template assisted non catalytic CVD approach. The infiltrated CNT/polymer composites were characterized by microscopic techniques such as infra-red and Raman spectroscopy. Small angle X-ray scattering (SAXS) has been employed to study the structural evolution and polymer confinement after the polymers are infiltrated in the aligned arrays of CNTs. A theoretical model has been used to understand and predict possible confinement effects of these polymers within the aligned CNT arrays, using self-consistent field theory (SCFT) and Monte-Carlo simulations based on the bond-fluctuation model.
