Covalent Organic Framework With Exceptional Water Sorption Properties

Patent Status

Additional Patents Pending

Brief Description

A new covalent organic framework (COF) with defective square lattice topology and exceptional water sorption properties stemming fro its unique framework structure. The COF exhibits a working capacity of 0.23 g(H2O)/g(COF) between 20 and 40% relative humidity without displaying hysteretic behavior. Furthermore, it maintains these promising water sorption properties after several uptake and release cycles. This material could be used as a sorbent for water harvesting or other water sorption related applications.

Suggested uses

This covalent organic framework can be used for a variety of water sorption applications, such as in:

• water harvesting devices to deliver water which can be used for human consumption or irrigation of crops
• heat pumps
• dehumidifiers
• adsorption refrigerators
• solar cooling systems

Advantages

higher water sorption (working) capacities and lower energy consumption in comparison to other sorbent materials
