Abstract
A composite adsorbent material includes a component that creates a localized electric field and a porous material where adsorption occurs, wherein the localized electric field extends into the porous material. The localized electric field created by the component controls adsorption properties of the porous material. The porous material may be microporous. The component may include ferroelectric material including a β-phase of polyvinylidene fluoride (PVDF), and wherein the porous material may include any of zeolites, silicas, activated carbons, covalent organic frameworks (COFs), polymers of intrinsic microporosity (PIMs), and metal-organic frameworks (MOFs). The MOFs may include any of HKUST-1, UiO-66, and UiO-66-NH. The β-phase of PVDF and the HKUST-1 may be electrospun together. The β-phase of PVDF includes aligned polymer chains that create the localized electric field extending within the porous material. The localized electric field enhances adsorption of an adsorbate, particularly a non-polar adsorbate such as oxygen or carbon dioxide, to the porous material.
