Two-dimensional (2D) polymers and methods for their formation are described herein. To create oriented 2D polymer films, monomers are combined with processing additives within a solvent, creating a solution that can be cast and dried to remove the solvent and form a solid film. The methods can enable transformation of the monomers into oriented films. Film quality can be controlled via multiple processing parameters, including monomer and additive concentrations, shear and elongational flow rates during casting, evaporation rates, and post-process rinsing, buffering, stretching, and thermal treatments. By combining stiff carbon-containing cyclic polymer nodal units with more compliant linear polymer bridge units in an ordered, 2D repeating molecular structure it is possible to tailor the mechanical properties of 2D polymers and their assemblies to provide high stiffness, strength, and toughness. The 2D polymer can also be combined with other 2D materials, linear polymers, or reinforcing materials to create 2D polymer composites.

Described herein are methods of preparing cutin-derived monomers, oligomers, or combinations thereof from cutin-containing plant matter. The methods can include heating the cutin-derived plant matter in a solvent at elevated temperature and pressure. In some preferred embodiments, the methods can be carried out without the use of additional acidic or basic species.

The present invention relates to processes for making compatibilized high aspect ratio barrier additives and polymer compositions that comprise compatibilized high aspect ratio barrier additives. The invention also relates to compositions produced by these processes, and articles formed from polymer compositions of this invention. The barrier additives provide passive barriers to gas molecules such as oxygen and carbon dioxide minimizing transit of such molecules through sidewalls of polymer articles containing the barrier additives.
