产品介绍

产品介绍：

PAN分子具有强极性的腈基团。它在自然情况上是相对不溶的。与其他聚合物前体相比，基于PAN的碳纤维具有非常高的强度。当进行热处理时，它可产生高的碳产率而形成热稳定性、高度定向性以及类似石墨的分子结构。从PAN基纤维生成碳纤维是三个过程的组合 - 即稳定化、碳化和石墨化。

产品用途：

聚丙烯腈（PAN）可被用作聚合物碳前体用于形成碳纤维，具有中孔宏观孔的电纺活性碳材料，碳黑添加剂。这些都是持续用于氢储备，EMI屏蔽，电化学，分离过程。它还可能在基于PAN的单壁碳纳米管复合材料中找到应用。

Product Introduction

PAN molecule has strong polar nitrile groups.It is relatively insoluble in nature. PAN based carbon fibers possess very high strength compared to other polymeric precursors. When subjected to heat treatment, it can produce high carbon yield giving rise to thermally stable, highly oriented, graphite like molecular structure. Generating carbon-fiber from PAN based fiber is a combination of three processes-- namely stabilization, carbonization and graphitization.

Product Usage
Polyacrylonitrile (PAN) is used as polymeric carbon precursor to form carbon fibers,?electrospun activated carbon materials having meso-macro pores,carbon black additives.These are consecutively used in hydrogen storage，EMI shielding,electrochemistry, separation processes.It may find applications in PAN based single walled carbon nanotube composites.
