摘要
通过采用气溶胶辅助化学气相沉积、激光切割、微笔直写等技术,制备了一种类石墨碳膜换能元。以正己烷为碳源,在Al2O3基底上沉积了一层厚度约2μm的碳薄膜,利用激光切割对碳膜形状进行控制以及微笔直写形成银电极,构成双V型碳膜桥换能元。利用扫描电子显微镜(SEM)、原子力显微镜(AFM)以及拉曼光谱(Raman)对碳膜的形貌及结构进行了表征,并对碳膜桥换能元的发火性能进行了研究。结果表明:碳膜桥的成型工艺简单有效,其发火区间窄,抗静电能力强,作用时间长,安全性可靠性高,能够实现对钝感药剂的点火。
By use of aerosol-assisted chemical vapor deposition,laser cutting and micro writing methods,a type of graphitic carbon film used as energy conversion component was prepared.Through adopting n-hexane as the carbon source,a carbon film with thickness about 2μm was deposited on the Al2O3 substrate.The shape of the carbon film was controlled by laser cutting and the silver electrode was formed by micro-direct writing,then double V-shaped carbon film bridge energy conversion component was formed.The morphology and structure of the carbon film were characterized by scanning electron microscopy(SEM),atomic force microscopy(AFM)and Raman spectroscopy(Raman),and the ignition performance of the carbon film bridge energy conversion component was studied.The results show that the forming process of the carbon film bridge is simple and effective,the carbon film bridge has a narrow firing range,strong antistatic ability and long ignition time,which show it has high safety and high reliability,meanwhile,it can realize the ignition of insensitive agents.
