Abstract
A method of making a porous structure is described herein. The method includes combining a hard material comprising a carbonaceous material, an inorganic material, or a combination thereof, with a polymer blend to provide a mixture; and heating the mixture to a temperature effective to template the hard material, degrade the polymer blend and provide the porous structure comprising the hard material. Porous structures having a a solid continuous phase and a gaseous dispersed phase are also provided.
Claims19
A method of making a porous structure, the method comprising:
- combining a hard material comprising
- a carbonaceous material,
- an inorganic material, or
- a combination thereof,
- with a polymer blend to provide a mixture;
- and
- heating the mixture to a temperature effective to template the hard material, degrade the polymer blend and provide the porous structure comprising the hard material;
- wherein the method does not comprise a freeze-drying step.
A porous structure comprising
- a solid continuous phase, and
- a gaseous dispersed phase,
- wherein the solid continuous phase comprises a hard material comprising
- a carbonaceous material,
- an inorganic material, or
- a combination thereof;
- wherein the porous structure comprises mesopores having an average diameter of 2 to 50 nanometers and macropores having an average diameter of greater than 50 nanometers;
- wherein the porous structure has a macropore area of greater than 10%;
- and
- optionally, wherein the porous structure has one or both of:
- an average pore volume of 0.5 to 1.5 cm3/g, and
- a specific surface area of greater than 75 m2/g.
