Near-infrared band wide-absorption inorganic-organic hybrid near-infrared absorbent and preparation method thereof

The invention discloses a near-infrared band wide-absorption inorganic-organic hybrid near-infrared absorbent and a preparation method thereof. The near-infrared absorbent is prepared from nano metal and an aza-pyrrole compound. The near-infrared absorbent has the beneficial effects that the near-infrared absorbent has excellent performance of broadband strong absorption, not only has the characteristics of stable structure and good high temperature resistance of an inorganic near-infrared absorbent, but also has the advantage of adjustable waveband of an organic near-infrared absorbent, and can be realized by adjusting functional groups of organic components, so that the application scene of the near-infrared absorbent is greatly expanded. 本发明公开近红外波段宽吸收无机有机杂化近红外吸收剂及制备方法。所述近红外吸收剂包括：纳米金属、氮杂吡咯化合物。本发明的有益效果在于：具备宽波段强吸收的优良性能，既有无机近红外吸收剂结构稳定，耐高温性良好的特点，又有有机近红外吸收剂波段可调的优点，通过调整有机组分官能团即可实现，从而大大扩展近红外吸收剂的应用场景。
