Porous Carbon (CNovel™)

CNovel™has a special, high-mesoporous structure which is unlike that of typical carbon materials like activated carbon. It is a new carbon material which has been considered difficult to obtain as an industrial material. One particular property is the structure called "inter-connected pores", which are mesopores connected to each other.

Features of CNovel™

Typical porous materials

Porous materials having a lot of pores. It is applied to filters and analytical instruments with its ability to adsorption/desorption. In recent years, there are finding spread application as energy storage devices.

Porous materials and their pores

Porous materials are classified into the following groups: microporous material, mesoporous materials and macroporous materials according to pore sizes. It is necessary to select suitable porous material depending on the target substance. CNovel™ is a mesoporous carbon material that has never been found in conventional carbon materials.

Controlled by proprietary technology "inter-connected pores"

CNovel™ having three-dimensional network structure are formed by controlled mesopores. One particular property is the structure called "inter-connected pores", which are mesopores connected to each other. This structure contributes to functional expression and functional improvement not seen in existing materials.

Control of chemical functions with surface structures

There are chemical species called functional groups on the surface of the carbon material, and the chemical properties of the surface change greatly depending on the presence or absence of the functional group. CNovel™ can control chemical functions without changing physical properties. Therefore, by controlling the surface condition, it is possible to control chemical functions such as wettability to water.

Function

Attractive and original functions

CNovel™ has functions that conventional activated carbon does not have.

High dispersibility

CNovel™ is a highly dispersible material due to its unique pore structure. It can be seen that CNovel™ is easily dispersed compared to other materials. High dispersion can also be expected for organic solvents and resins.

Selectable pore size

Controllable both pore distribution and particle size as narrow range. Material design is possible according to customer's request. )

High blackness

CNovel™ has a very high degree of blackness (* L is low) compared to conventional black pigments and achieves deep, pure black. Development is expected for various applications where jet black is required. Furthermore, it is a pigment that can be easily prepared ink because of its high dispersibility compared to carbon black.

Position of CNovel™ in color space You can see that CNovel™ is blacker than titanium black, iron oxide and carbon black.

Application example

Electrochemical applications for EDLC

In electrical double layer capacitors (EDLC), CNovel™ enables the design of electrodes with excellent characteristics both rate and low temperature due to its "interconnected structures".

Adsorption/desorption application： Flow filtration, Selective adsorption

CNovel™ has quick adsorption performance compared to general activated carbon. Quick adsorption/concentration leads to shortening of process time and downsizing of processing equipment. Enable large molecules(e.g. protein, enzyme) separation and adsorption on designed mesopore size.
