Abstract
Disclosed herein are methods for preparing sporopollenin exine capsules (SECs) and methods for preparing composite materials that comprise SECs that utilize ionic liquid compositions. The composite materials typically include structural polymers and the SECs, and the SECs optionally may encapsulate useful materials, such as flame retardant materials, phase change materials, and therapeutic materials, such as probiotics and prebiotics. The composite materials may be prepared from ionic liquid compositions comprising the structural polymers and the SECs which optionally may encapsulate the useful materials, where the ionic liquid is removed from the ionic liquid compositions to obtain the composite materials comprising the SECs.
