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 ofly can be applied to the generate electricity preparation method of fiber and yarn of miniature, high-performance electronic apparatus and the bacteria cellulose base of the self-powered of sensor.
Background technology
Along with the development of economic society, electricity has been a part indispensable in society.The present power status of China is city short of electricity, remote without 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 make the cost of electric power go up not down.The data demonstration that China Electricity Council issues, within 2011, China's power consumption reaches 4.69 trillion kilowatt hours, increases by 11.7% on a year-on-year basis.Within 2010, the maximum breach of power supply and demand is 3,000 ten thousand kilowatts; Meeting maximum breach during the kurtosis summer is 2,500 ten thousand kilowatts.At present, generated energy far can not meet the demand of economic growth.
But capacity of installed generator also reducing year by year, within 2011, the newly-increased capacity of installed generator in the whole nation has exceeded 9,000 ten thousand kilowatts, but the scale in fact effectively increasing reduces.Thermoelectricity is China generating main force, but thermoelectricity loses year after year and make electricity enterprise lose investment drive and ability, and thermoelectricity investment declines continuously and healthily, is reduced to fast 1,054 hundred million yuan in 2011 by 2,271 hundred million yuan in 2005.The variation of weather causes occurring that extremely cold, 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 expand certainly, estimate will reach for 2012 5000 ten thousand kilowatts.Electric power supply is not enough causes " hard short of electricity " phenomenon unavoidable.Moreover from far-off regions due to landform and fund, a lot of local power supplies are restricted does not even also switch on.Military combat, interchange, traffic etc. when pleasure trip on foot are because entrained electric weight is limited and can not remain permanent, for meagrely-populated region, the supply of power equipment is also a problem, current all more complicated and big energy-consumings of large-scale TRT, the manufacture of small-sized electric generating apparatus, reclaim and improperly all can cause very large harm to environment.Therefore, the Technology Need that we are present, the self power generation of generating electricity, to improve electricity usage efficiency, reduces electric power conveying process, reduces costs, and from life, immediately obtains our needed electric energy.
The development of microelectronics and micro-fabrication technology makes the micro-system 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, more and more lower to the requirement of power consumption, the research that volume and size have been entered to nanoscale.
Nanometer technology, as the important emerge science technical field of 21 century, is just experiencing high speed development in theory and practice.A large amount of novel nano device and materials are constantly developed, for people's life brings more facility.Meanwhile, be also that we have brought the clean technologies that solve energy crisis from microelectric technique research aspect.
But Nano-technology Development is to today, large quantity research is all to concentrate on to develop high sensitivity, high performance nano-device, almost without any the research of the power-supply system about 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 is all directly or indirectly to derive from battery.Sensor can provide power supply to oneself from own in object, thereby the miniaturization that simultaneously realizes device and power supply is the target of researcher's Recent study.
Since Curie brother finds that in quartz crystal piezo-electric effect starts, people are just devoted to mechanical energy to be converted into the research of electric energy always.Conventional piezoelectric, because of its electric property, although can form potential change, can not form the Schottky barrier with unilateral conduction as metal, thereby can not reach this process of release that gathers of energy.Thereby piezoelectric circuit generally needs a complicated external circuits to complete the output of electric energy now.And conventional piezoelectric causes piezoelectric structure can not accomplish miniaturization because crystal structure is too complicated, say nothing of the high-quality piezoelectric structure of nanoscale.But when the metal oxide such as zinc oxide and silica enters after the research category of piezoelectric fabric, 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. in 2011 and Chinese scientist's joint study have gone out taking zinc oxide nanowire as basic a kind of piezoelectric nano generator, realized on nanoscale mechanical energy is converted into electric energy.But present material, because of the sharply reduction mediocre and efficiency under wet environment of its overall work efficiency, can not come into operation well.
