根据小形变时的简单梁理论,给出了由碳纳米管悬空部分粘附时的几何形貌来计算平行碳纳米管之间粘附力的理论模型,推导了平行碳纳米管之间粘附力的计算公式以及碳纳米管粘附到沟槽基底时与沟槽基底的粘附力计算公式.由于碳纳米管本身的尺度小,实验上无法直接测量出平行碳纳米管之间的粘附力.本研究给出的计算公式可以由扫描电子显微镜(SEM)下观测到的碳纳米管悬空部分粘附时的几何形貌计算出平行碳纳米管之间的粘附力.根据文献中给出的平行碳纳米管之间粘附力的理论计算结果,估算了不同间距的平行碳纳米管能够粘附在一起所需要的槽口宽度,以及碳纳米管恰好粘附到沟槽基底时不同槽口宽度和深度之间的对应关系.这些结果对制备用于测量平行碳纳米管之间粘附力的悬空结构提供了重要的参考价值.
