Description
Technical field
The invention belongs to high efficiency filter technology, it is particularly a kind of with the electric nano generator that rubs be the high efficient protected of filter layer
Mouth mask.
Background technology
The technology of preparing of friction nanometer power generator has reached its maturity, and its open-circuit voltage and short circuit current are from initial several volts
Special (V) and a few nas (nA), be developed to it is present reached open-circuit voltage V up to ten thousand, several mA of short circuit current, or even to the level of A.
Its application field, also from acoustic energy, the low-frequency vibration in initial driving portable electric appts, sensor, collection switching environment
Mechanical energy, tide energy, wind energy etc. are extended to the research of bio-compatible friction nanometer power generator and possible biomedical applications, and
Show wide application prospect.
Used as developing power, fossil energy (such as coal, oil, natural gas) efficiency of combustion is low, is always city for China
What city developed is denounced, and with the enhancing of China's national power, living standards of the people are increasingly improved, and versatility automobile has come into thousand
Ten thousand families, but influence of the thing followed haze to people's life and quality of life is increasing.From some big or middle urban environments
The time ratio that Monitoring Data can be seen that serious haze weather has reached 66.6%.Such weather seriously threatens people
It is healthy, especially in air particle diameter less than 0.3 μm of particle, once more likely penetrate blood oxygen barrier in suction lung,
Produce lesion.Equally, it is even more the puzzlement for enduring " silicosis " to the fullest extent for the workman for being worked in dust atmosphere throughout the year.Therefore, based on body
The consideration of body health, increasing people have selected and wear masks.Conventionally produced mouth mask, its dust-proof approach is relied primarily on
The mechanism such as Direct Acquisition, inertial deposition, gravity sedimentation and diffusional deposition, can the larger dust granules of filter sizes, and for
Particle diameter is in the particle of 0.3-1.0 μ m in size, and its filter efficiency is not ideal enough.So, the mankind are a kind of new in the urgent need to seeking
Strobe utility, and the excellent protective mask of strainability is prepared, meet special industrial and civilian demand.
At present, it is only confined in overcoat for the research of Electrostatic Absorption filter face mask and adds single layer of electret material,
However, decay because electret Electrostatic Absorption ability in itself can be raised with temperature, and due to the electricity distribution on electret
Limited, when the charged particle of absorption reaches certain electricity, the adsorption effect of electret is just greatly reduced, so that mouth mask is removed
Dirt effect is not ideal enough.Therefore, with reference to the development opportunity of current friction electric generator, stomodaeum cover filtering material-non-woven fabrics is entered
Row nano surface is modified, and adds the modified copper mesh of another nano aluminum as frictional layer pole plate, and design and exploitation one kind are with the electricity that rubs
Nano generator is the high efficiency dustproof filtering mouth mask of filter layer, and improves its tolerance.The mentality of designing of this gauze mask and
Preparation method has no relevant report both at home and abroad at present.
