A system of silicon nanosheets and a diaryliodonium salt was found to initiate cationic and radical polymerizations. The polymerization relies on a syngergistic interaction between the silicon nanomaterial and the diaryliodonium salt, whereby the silicon nanomaterial acts as a co-initiator, inducing the decomposition of the diaryliodonium salt. The decomposition products, in turn, are able to initiate both cationic and radical polymerizations thereby enabling a mild and straightforward reaction procedure to obtain a variety of polymer/nanomaterial composites with cationically and radically polymerizable monomers. Most importantly, this work highlights the potential of using silicon nanomaterials' unique properties not just for physical applications, but also in chemical applications.
一个硅纳米片和二芳基碘鎓盐的体系被发现可以引发阳离子聚合和自由基聚合。聚合依赖于硅纳米材料和二芳基碘鎓盐之间的协同相互作用，其中硅纳米材料作为共引发剂，诱导二芳基碘鎓盐的分解。分解产物反过来又能够引发阳离子聚合和自由基聚合，从而使温和且直接的反应过程能够获得具有阳离子和自由基可聚合单体的各种聚合物/纳米材料复合材料。最重要的是，这项工作强调了利用硅纳米材料独特性质的潜力，不仅在物理应用中，而且在化学应用中也是如此。
