* 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

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.

* 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.
