Description
Technical field
The utility model belongs to technical field of plasma, and in particular to a kind of plasma-initiated polymerization device.
Background technology
Plasma polymerization is using discharging that organic gaseous monomer is plasmarized, it is produced all kinds of spikes,
The method for forming polymer by carrying out addition reaction between these spikes or between spike and monomer.Plasma polymerization can
Being divided into plasma state polymerization and two kinds of forms of plasma-initiated polymerization, their difference is：Plasma state polymerization is whole
Monomer is completely exposed to plasma environment in course of reaction, and gas only passes through in a short time in plasma-initiated polymerization
The plasma that glow discharge is formed, make monomer vapours that gas phase reaction generation activated centre occur, trigger monomer vapours when long
Between carry out polymerisation in the subsequent process without plasma.Complicated, reaction weight with plasma state polymerizate be present
The problem of existing property is poor, and treatment effect is decayed with the time is compared, and plasma-initiated polymerization mode can be with the knot of less destruction monomer
Structure, retain monomer premium properties, make polymerizate structure more single, be easily formed linear macromolecule product；On the other hand, lead to
Cross and graft reaction occurs with material surface, the adhesive force on surface can be strengthened, coating result is not decayed with the time.
It can be seen that the necessary condition for realizing plasma-initiated polymerization, which is plasma, periodically fires sterilized journey.It is existing
Plasma-initiated polymerization technology is realized by impulse modulation high frequency glow discharge, such as document《Face coat》(CN
A kind of hydrophobic and/or oleophobic base material 1190545C) is disclosed, polymerization is prepared including using impulse modulation high frequency glow discharge
The method of thing coating；Document《Apply the method for conformal nano coating by low pressure plasma process》
(CN201180015332.1) method for being directed to prepare polymer coating using impulse modulation high frequency glow discharge.These are existing
Technology uses impulse modulation high frequency glow discharge, is because can be avoided using high-frequency discharge because electrode is exhausted by polymerizate
Discharge off caused by edge, high-frequency discharge can also maintain in the case of being insulated even if electrode by polymerizate, and use arteries and veins
Modulated make high-frequency discharge periodically on/off be in order to meet required for plasma-initiated polymerization short time electric discharge and
Long-time discharge off polymerize.However, the method for impulse modulation high frequency glow discharge is needed to use and had used by prior art
The high frequency electric source of impulse modulation function, its shortcoming are：Impulse modulation high frequency electric source is complicated, price is high, is not easy to debug；Pulse
It is poor to modulate plasma stability caused by high-frequency discharge；It is high to discharge electrode structure and process and assemble required precision, technique
Repeatability is poor.

Fixed metal straight rod and rotation metal straight rod quantity can as, can also be different, due to two groups of metallic rods all
It is equidistant, if quantity is the same, discharging can occur to extinguish simultaneously simultaneously between a pair of metallic rods, if quantity is different, two
Group metallic rod some the extinguishing left, is discharged with asymmetry spatially close to there is remote, close electric discharge, but with
Time integral effect is also space uniform, and plated film result is not influenceed.
The fixed electrode is formed with rotating electrode turns electrode group surely.
Any cross section of chamber body inwall of the vacuum chamber sidepiece for same diameter circle or the identical length of side regular polygon,
The regular polygon is when number is at least 6；The top cover and bottom of the vacuum chamber are transversal with the sidepiece chamber body inwall of vacuum chamber
The flat board or domes of face matching.
The blast pipe is vertically arranged on the central shaft in vacuum chamber, blast pipe one end stretch out vacuum chamber after with vavuum pump
Connect, perforate on the tube wall of the blast pipe.
The exhaust bore is 25-100mm, and uniform pore openings on its tube wall, aperture 2-30mm, hole is at intervals of 2-
100mm。
The fixed electrode connects high frequency electric source output end, the rotating electrode ground connection；The frequency model of the high frequency electric source

Two groups of metallic rods can be close minimum range, distance 1-5cm is putting under usual plasma coating air pressure 0.1-100Pa
Electrical distance, guarantee reliably to discharge, can not all discharge apart near or remote or excite electric arc.
The fixed metal straight rod and the diameter range for rotating metal straight rod are 1-20mm, and material is copper, aluminium or iron.It is fixed
Metal straight rod and rotate metal straight rod diameter it is smaller, its can caused by electric field it is stronger, be more prone to discharge, discharge space office
Domain property is also better, but its rigidity is weaker, and the diameter range is to consider discharge space locality and rigidly obtain optimal
Value range.
The adjacent two fixed metal straight rods or adjacent two spacing rotated between metal straight rod are more than 15cm.It is above-mentioned
Spacing more than 15cm is the distance that usual plasma coating air pressure 0.1-100Pa decentralization electric energy enough extinguishes, less than this away from
From electric discharge will be likely to extinguish.
What the rotating speed of rotating electrode changed is the frequency of electric discharge and extinguishing, and influence of the rotating speed to coating effects is actually
The influence of discharge cycle, according to being particularly applicable on the plated film of different materials, the rotating speed of Different Optimization can be used.
It is of the present utility model with turn surely electrode group plasma-initiated polymerization device work when, by pending base material
It is placed in the space that rotating electrode surrounds, vector gas and monomer vapours is passed through vacuum chamber by the road, opening high frequency electric source makes
Continuous output high frequency power, and rotate rotating electrode.Rotating electrode rotate make its rotate metal straight rod periodically it is close and
Fixation metal straight rod away from fixed electrode, electric discharge generation plasma, plasma extinguishment when remote, so as to produce when close
The plasma to go out is periodically fired, makes monomer vapours that initiated polymerization occur and is deposited on substrate surface formation polymer painting
Layer.
The beneficial effects of the utility model are：
(1) the utility model is simple in construction, price is low, debugging is easy, wherein the high frequency electric source used does not need pulse to adjust
System, the high frequency electric source of impulse modulation function, its shortcoming are：Impulse modulation high frequency electric source is complicated, price is high, is not easy to debug；
Plasma stability caused by impulse modulation high-frequency discharge is poor；It is high to discharge electrode structure and process and assemble required precision,

Principle and structure are all fairly simple.
(2) plasma caused by the utility model device has good plasma stability, discharge electrode structure and added
Frock matches somebody with somebody the advantages that relatively low required precision, good process repeatability.
Current impulse modulation high-frequency discharge needs accurate matching synchronous, discharge electrode structure between same batch facility,
The time delay of process and assemble and synchronous transmission of signal line is slightly different, will produce the difference of high frequency matching, cause electric discharge
The larger difference of effect, coating effects under same technological parameter is produced larger difference so that process repeatability compared with
Difference.The plasma polymerization of the utility model patent realizes interrupted plasma by the way of mechanical rotation movement
Produce, high frequency electric source continuously exports, it is not necessary to accurate matching is synchronous, discharge electrode structure and process and assemble required precision compared with
Low therefore even if in the presence of certain machining tolerance, the electric discharge of its plasma is influenceed nor very significantly, so plasma is steady
Qualitative good, good process repeatability.
