Abstract
Forming multifunctional materials and composites thereof includes contacting a first material having a plurality of oxygen-containing functional groups with a chalcogenide compound, and initiating a chemical reaction between the first material and the chalcogenide compound, thereby replacing oxygen in some of the oxygen-containing functional groups with chalcogen from the chalcogen-containing compound to yield a second material having chalcogen-containing functional groups and oxygen-containing functional groups. The first material is a carbonaceous material or a macromolecular material. A product including the second material is collected and may be processed further to yield a modified product or a composite.
Claims31
A method comprising:
- contacting a first material having a molar mass of at least 500 g/mol and comprising oxygen-containing functional groups with a chalcogenide compound comprising at least one chalcogen;
- and
- initiating a chemical reaction between the first material and the chalcogenide compound, thereby replacing oxygen in some of the oxygen-containing functional groups with chalcogen from the chalcogenide compound to yield a second material comprising chalcogen-containing functional groups and oxygen-containing functional groups,
- wherein the chalcogenide compound is a solid or a liquid with a boiling point greater than 50° C. at 100 kPa comprising:
- at least one chalcogen selected from the group consisting of sulfur, selenium, and tellurium, and
- at least one element selected from Groups 1, 2, and 13-16 in the periodic table;
- and
- wherein at least one chalcogen in the chalcogenide compound is not bonded to oxygen or hydrogen.
A product formed by a process comprising:
- contacting a first material comprising oxygen-containing functional groups with a chalcogenide compound comprising at least one chalcogen;
- and
- initiating a chemical reaction between the first material and the chalcogenide compound, thereby replacing oxygen in some of the oxygen-containing functional groups with chalcogen from the chalcogenide compound to yield the product comprising chalcogen-containing functional groups and oxygen-containing functional groups,
- wherein the material comprises:
- a carbonaceous nanomaterial having a molar mass of at least 500 g/mol and a carbon:hydrogen ratio of at least 0.5;
- or
- an organic macromolecular material, a biological macromolecular material, or a modified biological macromolecular material having a molar mass of at least 500 g/mol and comprising a repeat unit having a molar mass of 200 g/mol or less,
- wherein the chalcogenide compound is a solid or a liquid with a boiling point greater than 50° C. at 100 kPa comprising:
- at least one chalcogen selected from the group consisting of sulfur, selenium, and tellurium, and
- at least one element selected from Groups 1, 2, and 13-16 in the periodic table;
- and
- wherein at least one chalcogen in the chalcogenide compound is not bonded to oxygen or hydrogen, and
- wherein the product comprises the second material.
