聚合物作为一种重要的材料类别,由于这些通用材料在正常使用过程中的老化失效,其应用受到极大的抑制。因此,人们普遍认为,对于长期应用而言,对热氧化老化的稳定化对于延长聚合物的使用寿命是必不可少的。然而,现有的抗老化技术的毒性和污染问题一直是困扰聚合物工业的难题。在此,可持续的碳纳米点(CD),通过简单和具有成本效益的微波辅助热解合成,首次用作自由基清除剂,以抵抗弹性体的热氧化老化。我们已经证明,所得CD的掺入可以是朝向高度耐老化弹性体的绿色和通用自由基清除剂。此外,通过用各种钝化剂控制CD的光致发光量子产率,实现了可调的自由基清除活性。我们第一次确定了衰老的...
The application of polymers as an essential class of material was greatly inhibited due to the aging failure of these versatile materials during normal use. Hence, it is generally recognized that stabilization against thermo-oxidative aging is indispensable to extend the service life of polymers for long-term applications. However, toxicity and pollution of the state-of-the-art antiaging technologies have long been puzzles in the polymer industry. Herein, sustainable carbon nanodots (CDs), synthesized by facile and cost-effective microwave-assisted pyrolysis, are used for first time as radical scavengers to resist the thermo-oxidative aging of elastomers. We have demonstrated that incorporation of the resultant CDs could be green and generic radical scavengers toward highly aging-resistant elastomers. Furthermore, by controlling the photoluminescent quantum yield of the CDs with various passivated agents, tunable radical scavenging activity was achieved. We established for the first time that the aging re...
