Description
Technical field
The present invention relates to the preparation method of a kind of bacteria cellulose base generating fiber and yarn, particularly a kind of bacteria cellulose base that can be applied to miniature, high-performance electronic apparatus and the self-powered of sensor preparation method of fiber and yarn that generates electricity.
Background technology
Along with the development of economic society, electricity has been a part indispensable in the society.The present power status of China is the city short of electricity, remote without the electricity, spring and autumn paddy, summer in winter peak.Although the engineering of transferring electricity from the west to the east has been opened by country, the power loss of long distance powedr transmission and high track laying expense then make the cost of electric power go up not down.The data demonstration of China Electricity Council's issue, China's power consumption reached 4.69 trillion kilowatt hours in 2011, increased by 11.7% on a year-on-year basis.The maximum breach of power supply and demand was 3,000 ten thousand kilowatts in 2010; Meet that maximum breach is 2,500 ten thousand kilowatts during the kurtosis summer.At present, generated energy far can not satisfy the demand of economic growth.
Yet capacity of installed generator is also reducing year by year, and the newly-increased capacity of installed generator in the whole nation had surpassed 9,000 ten thousand kilowatts in 2011, but the scale that in fact effectively increases reduces.Thermoelectricity is China generating main force, yet thermoelectricity loses electric look forward to losing investment drive and the ability of making year after year, and continuously and healthily decline of thermoelectricity investment was by 2,271 hundred million yuan of 1,054 hundred million yuan of reducing to fast 2011 in 2005.The variation of weather causes occurring extremely trembling with fear, very hot weather and electric coal price lattice continue the anxiety that run at high level has also aggravated electricity consumption.Therefore, a few years from now on electric power breach will continue to enlarge certainly, estimate will reach 5,000 ten thousand kilowatts in 2012.Electric power supply is not enough to cause " hard short of electricity " phenomenon unavoidable.Moreover from far-off regions owing to landform and fund, a lot of places power restricted even also do not have and switch on.Military combat, interchange, traffic etc. during pleasure trip on foot because entrained electric weight limited and can not keep permanent, for meagrely-populated zone, the supply of power equipment also is a problem, present large-scale TRT is more complicated and big energy-consuming all, the manufacturing of small-sized electric generating apparatus, reclaims and improperly all can cause very large harm to environment.Therefore, the Technology Need that we are present, the self power generation of namely generating electricity to improve electricity usage efficient, reduces the electric power conveying process, reduces cost, instant our the needed electric energy that obtains from life.
The development of microelectronics and micro-fabrication technology makes the micro-systems such as wireless sense network and microactrator be widely used in environmental monitoring, body and is implanted into biochip, automobile, building, the key areas such as military.Along with going deep into of research, the pursuit to function of MEMS is more and more stronger, and is more and more lower to the requirement of power consumption, the research that volume and size have then been entered nanoscale.
Nanometer technology is just experiencing high speed development as the important emerge science technical field of 21 century in theory and practice.A large amount of novel nano device and materials constantly are developed, for people's life brings more facility.Simultaneously, also the clean technologies that solve energy crisis have been brought for us from microelectric technique research aspect.
Yet Nano-technology Development is to today, and large quantity research all is to concentrate on to develop high sensitivity, high performance nano-device, almost without any the research about the power-supply system of nanoscale.But the nano-sensor that is applied to the aspects such as biological national defence is urgent all the more because of the lifting of technology to the demand of this power supply.In general the power supply of these devices all is directly or indirectly to derive from battery.Sensor can ownly in the object provide power supply to oneself, thereby the miniaturization that realizes simultaneously device and power supply is the target of researcher's Recent study.
Since Curie brother finds that in quartz crystal piezo-electric effect begins, people just are devoted to mechanical energy is converted into the research of electric energy always.Conventional piezoelectric although can form potential change, can not form the Schottky barrier with unilateral conduction because of its electric property as metal, thereby can not reach this process of release that gathers of energy.Thereby piezoelectric circuit generally needs the external circuits of a complexity to finish the output of electric energy now.And conventional piezoelectric causes piezoelectric structure can not accomplish miniaturization because crystal structure is too complicated, says nothing of the high-quality piezoelectric structure of nanoscale.But enter the research category of piezoelectric fabric when metal oxides such as zinc oxide and silica after, its simple chemical composition and crystal structure bring up the easy control of its purity, size, pattern.It becomes rapidly the important materials of current piezoelectric research as the electric conductivity of metal oxide with as the power generation performance of piezoelectric excellence.
The scientist Wang Zhonglin leader's of Chinese origin of the georgia ,u.s.a Institute of Technology in 2006 scientific research group develops a kind of novel plated zinc oxide nanofiber that can produce electric energy, and at motor driving because piezo-electric effect produces electric energy; The U.S. had gone out take a kind of piezoelectric nano generator of zinc oxide nanowire as the basis with Chinese scientist's joint study in 2011, had realized on nanoscale mechanical energy being converted into electric energy.But present material can not come into operation well because of the rapid reduction mediocre and efficient under wet environment of its overall work efficient.
