概要（目的・用途・実施内容）/ Abstract (Aim, Use Applications and Contents)
In this research project, we aimed to control the nanostructure and create new functions using the self-organization of block copolymers. We mainly investigated the morphology and size of these nanoaggregates formed in water using scanning and transmission electron microscopy.
実験 / Experimental
Transmission electron microscopy (TEM) observations were conducted to examine the morphology and size of the aggregates in water. Each polymer dispersion was stained with phosphotungstic acid solution and dropped onto a carbon-supported copper grid that had been hydrophilized using a JEOL HDT-400. Observations were performed using a JEOL JEM-1400 at an acceleration voltage of 120 kV.
結果と考察 / Results and Discussion
By introducing intermolecular interactions other than hydrophobic interactions into diblock amphiphilic block copolymers and by varying the molecular weight of block copolymers, it was suggested that the morphology, size, and size distribution of self-organized nanostructures on the sub-micron to sub-nano scale could be controlled.
