The effect of a high-power ion beam of nanosecond duration on layers of chlorinated polyvinyl chloride with a catalytic additive (ferrocene), which preliminarily underwent treatment in air or an inert medium in the temperature range 100–400°C, is studied. Heat treatment at 150°C for 1 h is shown to reduce the length of the formed carbon nanofibers by ~20 times. Disk-shaped depressions are observed on the surface of the polymer irradiated after treatment at 200°C due to the removal of a part of the surface layer. These depressions are likely associated with polymer embrittlement during heat treatment. A net-like structure is observed between these depressions. An increase in the treatment temperature to 400°C (in an inert medium) results in the formation of nanofibers with a length not exceeding 0.5 μm. The effect of preliminary heat treatment on the growth of carbon nanofibers and possible mechanisms of their growth under the influence of a high-power ion beam on a chloropolymer containing a catalytic additive is discussed.

大功率离子束辐照对氯化聚氯乙烯的初步热处理对其表面碳纳米纤维形成的影响

研究了纳秒级大功率离子束对含催化添加剂（二茂铁）的氯化聚氯乙烯层的影响，该催化剂已在空气或惰性介质中进行了初步处理，温度范围为100-400°C。已显示在150°C下热处理1小时可将形成的碳纳米纤维的长度减少约20倍。由于除去了部分表面层，在200℃下处理后的聚合物表面上观察到圆盘状的凹陷。这些凹陷可能与热处理过程中的聚合物脆化有关。在这些凹陷之间观察到网状结构。将处理温度升高至400℃（在惰性介质中）会导致形成长度不超过0.5μm的纳米纤维。
