High-performance alginate supramolecular plastics enabled by pre-hydroplastic processing and post-noncovalent crosslinking.

ABSTRACT: Petroleum-based plastics have raised global concerns in recent years. Degradable bio-based supramolecular plastics (SPs), coupled with eco-friendly hydroplastic processing, become sustainable alternatives. However, the inherent contradiction between hydroplastic processability and water-resistance restricts their applications in humid environments. Here, we report a cascade strategy of pre-hydroplastic processing and post-noncovalent crosslinking to stepwise achieve hydroplastic processing and water-resistance of alginate SPs. Alginate-cetyltrimethylammonium (SA-CTAB) SPs are firstly processed into various two-dimensional/three-dimensional shapes due to the excellent hydroplasticity. Then, Ca²⁺ ions are introduced to improve the mechanical strength, water-resistance, and flame r
