可溶性酚醛树脂是通过碱催化的苯酚-甲醛缩合与三维交联框架获得的树脂。它们被认为是高度耐化学性的，因此煅烧通常用于甲阶酚醛树脂型树脂的处理，这显著限制了可以从甲阶酚醛树脂型树脂衍生的纳米结构材料的多样性。在此，我们报告，所选的金属硝酸盐溶液可用于通过氧化溶解过程溶解各种类型的纳米结构的甲阶酚醛树脂。这种策略不仅可以控制甲阶酚醛树脂的溶解，更重要的是提供了一种新的方法来选择性地蚀刻甲阶酚醛树脂基纳米复合材料，以产生各种具有前所未有的结构和巨大的生物应用潜力的纳米结构材料。
Resoles are resins obtained by base-catalyzed phenol-formaldehyde condensation with a three-dimensional cross-linked framework. They are considered as highly chemical-resistant, and calcination is thus generally used in the treatment of resole-type resins, which significantly limits the diversity of nanostructured materials that can be derived from resole-type resins. Herein, we report that selected metal nitrate solutions can be used to dissolve various types of nanostructured resoles through an oxidative dissolution process. This strategy not only enables the controlled dissolution of resoles, but more importantly provides a new approach to selectively etch resole-based nanocomposites to give rise to a variety of nanostructured materials with unprecedented architectures and great potential in bioapplications.
