Oxidative Dissolution of Resoles: A Versatile Approach to Intricate Nanostructures

Chao Liu, Yang Liu, Hao Song, Min Zhang, Chengzhong Yu, Yannan Yang, Xiaodan Huang
Resoles are base-catalyzed phenol-formaldehyde resins with a 3-dimensional cross-linked framework. The chemistry of resoles is generally considered as highly chemical resistant, thus calcination is always used in the treatment of resole-type resin, which significantly limit the diversity of nanostructured materials derived from resole-type resins. Here we report that selected metal nitrate solutions can be applied to dissolve various types of nanostructured resoles through an oxidative dissolution mechanism. This strategy not only allows for controlled dissolution of resoles, but more importantly provides a new approach to selectively etch resole based nanocomposites, giving rise to a variety of nanostructured materials with unprecedented architectures and great potential in bio-applications.
