Feature of Research
Hybridization of inorganic compounds involving radionuclides with organic compounds is a useful method for their separation and effective utilization. Since the functionalities often appear at the interfaces between organic and inorganic components, surface modification technique, which is effective functionalization only by a small amount of organic components, is important for realization of a low-carbon society. Taking advantages of the organically surface modification of inorganic nanomaterials, we are challenging to create functional nanomaterials that lead to realizing a carbon neutral society.
Outline of Research
- Nanoparticle materials that functions can be controlled in response with external stimuli
Stimuli-responsive polymers are well-known to exhibit reversibly change of their properties in response to external stimuli such as temperature and pH. We are developing separation nanomaterials modified with the polymers that can control the adsorption/desorption of solutes and the dispersion/precipitation of matrices by applying external stimuli. We also examine to create functional nanofillers that allow self-repairing properties and toughness to commercial-available polymer materials by surface modification with molecules having reversible chemical bonds in response to environmental changes.
- Nanosheet materials with two-dimensional nanospaces
By selective organically modification onto the interlayer surfaces of inorganic layered compounds, we can create a double-layered nanosheet through their controlled exfoliation. Since the interlayer of the double-layered nanosheets has a two-dimensional nanospace with an extremely high aspect ratio, we are promoting its application to drug-encapsulated nanocarriers and battery nanomaterials with conduction paths for electrolyte ions by designing the interlayer surface modification.
