概要（目的・用途・実施内容）/ Abstract (Aim, Use Applications and Contents)
The aims of the experiment: (1) to measure the particle size distribution, and (2) to determine the surface and pore porosity.
実験 / Experimental
(1) A dynamic light scattering (DLS) particle size analyzer (ELSZ-2000, Otsuka Electronics, Japan) was used to measure the particle size distribution in the ketjen black ink.
(2) The surface area and porosity were determined through N2 adsorption desorption experiment by automatic volumetric adsorption equipment (BELSORP-mini II, Japan) and calculated with the Brunauer-Emmett-Teller (BET) analysis.
結果と考察 / Results and Discussion
(1) The volume distribution value of particle size (D90) of 0.0010% (w/v) ketjen black ink in the initial state was 160.5 nm and was thus much smaller than the required 540 nm. No aggregate particles larger than 400 nm were present. Compared with the ketjen black ink after 120 days, the D90 value showed a minor change to 179.6 nm, which indicates the long-term stability of the formulated ketjen black ink.
(2) The N2 adsorption and desorption isotherms were obtained, and the surface area and porosity of the non-imprinted sol-gel (NISG) and molecular imprinted sol-gel (MISG) materials were measured by BET analysis. The adsorption−desorption curves can be identified as type IV hysteresis loop according to the IUPAC classification, indicating that both NISG and MISG are mesoporous materials (pore diameter in 2−50 nm). The pore size of the NISG material and MISG material was 3.23 and 4.46 nm, respectively, which indicates the template material results in the formation of larger cavities. In addition, the surface area of the MISG material was 3.76 times higher than that of the NISG material, which suggests that the former is more suitable for the binding of more target molecules.
