PAPER: Fine particles on bio-composite surface. ココナツ殻由来素材の表面に微粒子を集積

Other “intro” of papers from our lab >> /tag/paper/

 


Open article in PDF

HIGHLIGHTS:
* Physical treatment on the biocomposite increases the surface roughness.
* Single bond COOH network on the treated biocomposite promotes the particle deposition.
* The network reduces the particles repulsion during the deposition process.

# Bio-composite(バイオコンポジット)is a composite material formed by a matrix (resin) and a reinforcement of natural fibers.生物由来素材を組み合わせて作った素材

A nanostructure derived from TiO2 particle deposition onto a biocomposite surface derived from coir dust (ココナッツ廃棄物) was developed to control degradation. The coir dust was obtained from coconut kernel waste (ココナツ殻の廃棄物) and underwent drying treatment before it was mixed with polypropylene (PP) as the substrate. The TiO2 suspension was spray dried onto a hot-pressed substrate (biocomposite) with a surface roughness between 0.23 and 1.57 μm.

PAPER: Between Charged Aerosol Particles & Substrate’s Hydrophilicity.(発見)正帯電した気中浮遊粒子が親水性が高い表面に付きやすい現象

pdf
Area-selective deposition of charged particles derived from colloidal aerosol droplets on a surface with different hydrophilic levels...J. Aerosol Science. (a work by Kusdianto (Doctoral student, now with ITS, Indonesia), Gen (Doctoral student, joined Tohoku Univ. then City Univ. Hong Kong), and Lenggoro.

Highlights
* Charged aerosol particles were derived from spraying colloidal droplets.
* Substrate with different ‘levels’ of hydrophilicity was used.
* Positively charged aerosol particles tended to approach the ‘more hydrophilic’ area.

異なる親水性度をもつ基板(表面)に対して、気相中に浮遊させた帯電微粒子の挙動を調べました。
【新規性】正に帯電された浮遊微粒子がより親水性度が高い表面に沈着(付着)する傾向にあることがわかりました。
【応用展開1】材料のパターン化技術のヒント
【応用展開2】植物表面における大気中浮遊粒子の沈着の研究のヒント

graphical-kusdianto2-revisedImmobilization of colloidal particles into sub-100 nm porous structures by electrophoretic methods in aqueous media

Kusdianto, Sasaki, Naim, Lenggoro, Colloids Surfaces A: 10.1016/j.colsurfa.2014.06.042

【新規性】新開発の「パルス型電気泳動法(Pulse-type Electrophoretic Deposition/EPD)」および従来EPD法を用いて、水中に浮遊する粒子を100nm以下の穴(ポーラス構造)に挿入・固定。世界初です。
【耐久性】ポーラス構造内に固体化された粒子に対して、超音波エネルギーをかけて、粒子の脱離を試みましたが、穴に粒子がちゃんと残こります。
【展開】酵素や触媒材料の固定化技術への応用
