| フッ化ビニリデン樹脂の応用展開：リチウムイオン二次電池用バインダー PVdF Binder of Lithium Ion Battery |
佐久間 充康 Mitsuyasu SAKUMA |
| ＜要旨＞ PVdF
(polyvinylidenefluoride) is a worldwide used polymer as a binder material
for lithium ion secondary battery electrodes. Characteristic features
of PVdF material satisfy the various functions required in the electrode
manufacturing process and battery performance. As an example of binder
function, the adhesive mechanism with the types of PVdF and their molecular
weight is shown in this paper. Keywords: PVdF / Binder / Lithium Ion / Battery / Electrochemical / Crystalline / Molecular Weight |
| パーフルオロポリエーテル化合物の合成と応用 Synthesis and Application of Perfluoropolyethers |
白川 大祐 Daisuke SHIRAKAWA |
| ＜要旨＞ Perfluoropolyethers
(PFPE) have an excellent fluidity and low surface friction. These fluorinated
oils are employed as grease, lubricant and modification in various fields.
As applications
require higher performance and reliability, the technology of the PFPE
is facing more challenging tasks regarding its tribological performance. Keywords: Perfluoropolyether / Fluorination / Lubricant / Hard Disk Drive |
| フルオロアクリレートホモポリマーの動的撥液性 Dynamic Liquid Repellency of Fluoroacrylate Homopolymers |
森田 正道・山本 育男 Masamichi MORITA and Ikuo YAMAMOTO |
| ＜要旨＞ The
effect of the α position structure of fluoroacrylate homopolymers with
short fluoroalkyl (Rf) chains on dynamic liquid repellency was characterized
by sliding angle and sliding velocity
values. We developed a Rf(Cn)α-Cl acrylate homopolymer, which shows a
very high dynamic liquid repellency compared with Rf(Cn) acrylate and
Rf(Cn) methacrylate. This result is suggesting that the surface molecular
mobility of Rf chains is restricted by α-Cl groups and the surface rearrangement
is hard to achieve. Keywords: Dynamic Liquid Repellency / Sliding Angle / Sliding Velocity / Contact Angle / Fluoroacrylate |

| 電荷輸送に最適な高分子骨格の探求 Investigation of Optimized Conjugated Polymer Backbone Structures for Charge Carrier Transport |
関 修平 Shu SEKI |
| ＜要旨＞ Recent
successful reports on the variety of organic and/or organic-inorganic
compounds with conjugated electronic systems based on covalent/non-covalent
chemical bondings have extended rapidly the feasibility of the compounds
as practical electronic devices. One of the most important properties
of the materials is the mobility of charge carriers because the value
is determining and dominating all the device performance including switching
rate, energy efficiency, reliability, etc. In the present paper, electrode-less
microwave conductivity measurement techniques have been applied to determine
the value of mobility in the conjugated macromolecular/supramolecular
systems, and we discuss comprehensively the mechanisms of charge carrier
transports in the materials in view of what are the formative processes
of the charge carrier transport in the respective three measurement systems.
This leads to the optimization of the mobility value in a variety of
the organic materials, making these materials a good choice to challenge the conventional inorganic semiconductor materials used by industries
and substitute them in part by the organic materials. Keywords: Conjugated Polymers / Mobility / Microwave / Time-of-Flight / Field-Effect-Transistor / Semiconductor/ Molecular Wires / Non-Contact / Ultra-High Pressure |
