The purpose of the present invention is to provide a polymer brush that is able to form a phase-separated structure even in a gaseous phase.
This polymer brush is characterized by a substrate, and by a polymer layer that has one end fixed to the substrate and in which the phase separation state between a polymer dense part and a polymer loose part changes reversibly.
|Scope of claims||
1. Kinds of high polymers brush, have: The parent metal, as well as fixes by the single margin in the above parent metal, but another end assumes the polymer level that the free electricity the plural number high polymer chain forms;
In above polymer level, between polymer close departments and polymer careless departments the discrete state is changes reversiblily.
2. According to claim 1, item of high polymer brushes, supposes when the above polymer level for the discrete state thickness has not been above 1nm and below 50nm;
The quantity mean molecular weight of above high polymer chain are over 2,000, and below 1 million.
3. According to claim 1, or 2 items of high polymers brush, above separates the structure uses the change of external environment but reversiblily control structure.
4. According to claim 3, item of high polymer brushes, the change of above external environment is, or the ion concentration change creates using the temperature and pressure.
5. 1 kinds separate the high polymer to brush, have: Parent metal;
As well as the polymer level, it is fixes by the single margin in the above parent metal, but another end assumes the free electricity the plural number high polymer chain to form;
Forms the polymer close department and polymer careless department in the above polymer level.
6. According to claim 5, item of high polymer brushes, the above close department of above polymer level is repeatedly appears in the plane direction previous periodicity with the careless department.
7. According to claim 5, or 6 items of high polymers brush, the above close department forms with the careless department institute separates the structure, is the island structure and column structure, altogether the continual structure or the laminated structure.
8. 1 surface condition control methods, because of causing the application patent scope the 1st to 7 items of any item of high polymers brush the contact resolver, causes the external environment change, but causes discrete state change that the high polymer brushes.
9. According to claim 8, surface condition control method, the change of above external environment is, or the ion concentration change creates using the resolver temperature and pressure.
10. 1 kinds separate the high polymer to brush the manufacture method, enables to have the parent metal, with Sigma (place /nm 2) to fix by the single margin according to the fixed end density in the above parent metal, but another end assumes the free electricity the plural number high polymer chain's high polymer to brush (A), as well as resolver (B), in causing the above high polymer chain cannot unify in the parent metal is under the free state, when with the above resolver mix phase diagram, by the following type (1) was decided that the polymer density the solution assumes temperature of the discrete state to have the contact, then, according to into this discrete state temperature range, and becomes the glass of shift temperature following temperature above polymer,The above resolver substitution is the gas phase;
Polymer density (volume %) =.sigma. (place /nm 2) * quantity of mean molecular weight high polymer chain (g/mol)x10 21/(in root-mean-square of terminals free high polymer chain distance (nm)x fainting constant Na (mol -1) * high polymer chain density (g/cm 3)) (1)
11. According to claim 10, item of high polymer brushes the manufacture method, the fixed end density of above high polymer chain Sigma is 0.001 (place /nm 2) above and 0.1 (place /nm 2) below.
12. According to claim 10, or the 11 items of high polymers brush the manufacture method, above resolver (B) is when with has not unified in the parent metal free state high polymer chain, according to the above type (1) decided when polymer density mix, the double node initial temperature is over 1.deg.C, and below 100.deg.C scope resolver.
13. According to claim 10, to 12 any one item separates the high polymer to brush the manufacture method, the combination of above polymer and resolver (B), is (1) polymer: The aromatic hydrocarbon is the polymer and resolver: The hydrocarbon is the resolver;
Or (2) polymer: (Methyl) acrylic acid series polymer and resolver: River system resolver.
14. 1 kinds separate the preparation of method structure, will apply for the patent scope the 1st to 7 items of any item of high polymers to brush, heats up to the glass shift temperature of polymer above.
15. 1 kinds of surfaces change the nature component, in the surface forms the application patent scope the 1st to 7 items of any item of high polymers to brush.
