대표청구항▼
1. A method of bonding two surfaces, the method comprising: contacting a surface of a plastic material with a polysiloxane material;removing the polysiloxane material from the surface of the plastic material;providing nitrogen or ammonia plasma to the surface of the plastic material that was contact
1. A method of bonding two surfaces, the method comprising: contacting a surface of a plastic material with a polysiloxane material;removing the polysiloxane material from the surface of the plastic material;providing nitrogen or ammonia plasma to the surface of the plastic material that was contacted with the polysiloxane material;providing oxygen plasma to a surface of a polysiloxane material; andcontacting the surface of the plastic material provided with nitrogen or ammonia plasma with the surface of the polysiloxane material provided with oxygen plasma to bond the surfaces together and provide a bonded product, wherein the bonded product is a microfluidic device. 2. The method of claim 1, wherein contacting the surface of the plastic material with the polysiloxane material before providing nitrogen or ammonia plasma to the surface of the plastic material comprises applying pressure between the surface of the plastic material and the polysiloxane material of at least 1 Pa. 3. The method of claim 1, wherein the polysiloxane material contacted with the surface of the plastic material before providing nitrogen or ammonia plasma to the surface of the plastic material is in a solid state. 4. The method of claim 1, wherein the polysiloxane material contacted with the surface of the plastic material before providing nitrogen or ammonia plasma to the surface of the plastic material is a polysiloxane film. 5. The method of claim 1, wherein providing nitrogen or ammonia plasma to the surface of the plastic material comprises exposing the surface of the plastic material to nitrogen or ammonia plasma at a plasma power of about 30 W to about 50 W and a gas flow rate of about 1 sccm to about 5 sccm for about 20 seconds to about 60 seconds. 6. The method of claim 1, wherein providing oxygen plasma to the surface of the polysiloxane material comprises exposing the second surface to oxygen plasma at a plasma power of about 70 W to about 100 W and a gas flow rate of about 30 sccm to about 50 sccm for about 60 seconds to about 180 seconds. 7. The method of claim 1, wherein contacting the surface of the plastic material provided with nitrogen or ammonia plasma with the surface of the polysiloxane material provided with oxygen plasma comprises applying pressure between the surfaces of at least 1 Pa. 8. The method of claim 1, wherein the plastic material is a carbon-based polymer. 9. The method of claim 1, wherein the plastic material is polyolefin, polystyrene, polycarbonate (PC), polymethacrylate (PMA), poly(methyl methacrylate) (PMMA), polytetrafluoroethylene (PTFE), polyvinylidene chloride (PVC), polyethylene terephthalate (PET), or a combination thereof. 10. The method of claim 1, wherein the polysiloxane material contacted with the surface of the plastic material before providing nitrogen or ammonia plasma to the surface of the plastic material, and the polysiloxane material provided with oxygen plasma, which may be the same or different, are each independently a material comprising a polysiloxane of Formula 1, wherein, R1, R2, and R3 are each independently hydrogen, an alkyl group, an aryl group, a cycloalkyl group, an alkoxy group, a hydroxyalkyl, an alkoxyalkyl group, and a hydroxyalkoxyalkyl group, each optionally substituted with a halo group,R4 is hydrogen, an alkyl group or an aryl group, each optionally substituted with a halo group,and n is an integer. 11. The method of claim 1, wherein the polysiloxane material contacted with the surface of the plastic material before providing nitrogen or ammonia plasma to the surface of the plastic material and the polysiloxane material provided with oxygen plasma, which may be the same or different, are each independently polydimethylsiloxane (PDMS) or polyphenylsiloxane. 12. The method of claim 1, further comprising performing an annealing process after bonding the surfaces. 13. The method of claim 1, wherein the plastic material comprises a microstructure. 14. The method of claim 1, further comprising providing oxygen plasma to a surface of the polysiloxane material opposite the surface contacted with the plastic material; andcontacting a surface of a second polysiloxane with the surface of the polysiloxane material opposite the surface contacted with the plastic material, to bond the surface of the second polysiloxane to the surface of the polysiloxane material opposite the surface contacted with the plastic material. 15. The method of claim 1, further comprising providing oxygen plasma to a surface of a second polysiloxane material, and contacting the surface of the second polysiloxane material with a surface of the polysiloxane material opposite the surface contacted with the plastic material, to bond the surface of the second polysiloxane to the surface of the polysiloxane material opposite the surface contacted with the plastic material. 16. The method of claim 1, further comprising providing oxygen plasma to a surface of the polysiloxane material opposite the surface contacted with the plastic material and a surface of a second polysiloxane; andcontacting the surface of the second polysiloxane with the surface of the polysiloxane material opposite the surface contacted with the plastic material, to bond the surface of the second polysiloxane to the surface of the polysiloxane material opposite the surface contacted with the plastic material. 17. The method of claim 16, wherein the second polysiloxane comprises a microstructure.
