Polymer Classification: Crystallinity

Polymer Classification: Crystallinity

Unlike ionic or small covalent molecules, polymers do not form crystalline solids due to the diffusion limitations of their long-chain structures. However, polymers contain microscopic crystalline domains separated by amorphous domains.
Crystalline domains are the regions where polymer chains are aligned in an orderly manner and held together in proximity by intermolecular forces. For example, chains in the crystalline domains of polyethylene and nylon are bound together by van der Waals...

Background:

Inorganic-organic mesophase materials offer tunable properties based on their nanoscale structures.
Achieving macroscopic orientational order and anisotropic properties in these materials is challenging due to complex synthesis processes.

Purpose of the Study:

To establish general criteria for preparing mesostructured materials with controlled orientational order.
To enable the synthesis of diverse mesostructured materials with aligned channels and controllable directionalities.

Main Methods:

Utilized a micropatterned semipermeable poly(dimethylsiloxane) stamp to manage nucleation and growth of self-assembling phases.
Controlled rates, directions, and surfaces of self-assembly processes.

Main Results:

Successfully prepared mesostructured silica, titania composites, and mesoporous carbons with high hexagonal order.
Achieved controllable orthogonal macroscopic orientational order in the synthesized materials.
Demonstrated novel anisotropic properties, including direction-dependent photocurrent generation.

Conclusions:

The developed method provides a pathway to engineer mesostructured materials with tailored anisotropic properties.
These materials show promise for enhancing functionality in separations, catalysis, and energy conversion applications.
