Uphuhliso lweteknoloji yeplastiki iyatshintsha ngosuku ngalunye oludlulayo.Ukuphuhliswa kwezixhobo ezitsha zezicelo ezitsha, ukuphuculwa kokusebenza kwemarike yezinto ezikhoyo, kunye nokuphuculwa kokusebenza kwezicelo ezizodwa kunokuchazwa njengemiyalelo emininzi ebalulekileyo yokuphuhliswa kwezinto ezintsha kunye nokutsha kwesicelo.Ukongeza, ukukhuselwa kwendalo kunye nokonakala kuye kwaba yinto ebalaseleyo kwiiplastiki ezintsha.
Ziziphi izinto ezintsha?
I-Bioplastics: I-Nippon Electric isanda kuphuhliswa i-bioplastics esekelwe kwizityalo, ezisebenza ngayo i-thermal conductivity ifaniswa nentsimbi engenasici.Inkampani ixube i-carbon fibers kunye nobude beemilimitha ezininzi kunye nobubanzi be-0.01 millimeters kunye ne-adhesive ekhethekileyo kwi-polylactic acid resin eyenziwe ngombona ukuvelisa uhlobo olutsha lwe-bioplastic ene-conductivity ephezulu ye-thermal.Ukuba i-10% ye-carbon fiber ixutywe kuyo, i-thermal conductivity ye-bioplastic ifaniswa naleyo yensimbi engenasici;xa i-30% ye-carbon fiber yongezwa, i-thermal conductivity ye-bioplastic iphindwe kabini yensimbi engenasici, kwaye ubuninzi buyi-1/5 kuphela yensimbi engenasici.
Nangona kunjalo, uphando kunye nophuhliso lwe-bioplastics lunqunyelwe kumacandelo e-bio-based ekrwada okanye i-bio-monomers okanye iipolymers eziveliswe yi-microbial fermentation.Ngokwandiswa kweemarike ze-bio-ethanol kunye ne-bio-diesel kwiminyaka yamuva nje, i-bio-ethanol kunye ne-glycerol zisetyenziswa njengezinto ezibonakalayo zokuvelisa.Itekhnoloji ye-bioplastics ifumene ingqwalasela eninzi kwaye iye yathengiswa.
Ifilimu yeplastiki entsha yokutshintsha umbala: IYunivesithi yaseSouthampton eUnited Kingdom kunye neDarmstadt Institute for Plastics eJamani baye baqulunqa ifilimu yeplastiki etshintsha umbala ngokudibeneyo.Ukudibanisa imiphumo yendalo kunye neyokwenziwa kwe-optical, ifilimu eneneni yindlela entsha yokwenza izinto zitshintshe umbala ngokuchanekileyo.Lo mboniso bhanyabhanya weplastiki oguqula umbala yifilimu yeplastiki ye-opal, eyenziwe ngamacandelo eplastiki abekwe kwindawo emacala-ntathu, kwaye iqulethe i-carbon nanoparticles encinci embindini we-plastiki spheres, ukuze ukukhanya kungabi kuphela phakathi kwe-plastiki spheres izinto ezingqongileyo.ukubonakaliswa okuvela kwimimandla esemaphethelweni phakathi kwezi ngqukuva zeplastiki, kodwa kwakhona ukusuka kumphezulu wekhabhoni nanoparticles ezizalisa phakathi kwezi ngqukuva zeplastiki.Oku kunzulu kakhulu umbala wefilimu.Ngokulawula umthamo weengqungquthela zeplastiki, kunokwenzeka ukuvelisa izinto ezikhanyayo ezisasaza kuphela i-spectral frequencies.
Igazi leplastiki elitsha leplastiki: Abaphandi kwiYunivesithi yaseSheffield eUnited Kingdom baye bavelisa "igazi leplastiki" elenziwayo elibonakala ngathi yintlama engqindilili.Ngethuba nje inyibilika emanzini, inokutofelwa kwizigulana, ezinokusetyenziswa njengegazi kwiinkqubo zongxamiseko.ezinye iindlela.Olu didi lutsha lwegazi lokwenziwa lwenziwe ngeemolekyuli zeplastiki.Kukho izigidi zeemolekyuli zeplastiki kwiqhekeza legazi lokwenziwa.Ezi molekyuli ziyafana ngobungakanani nangokumila kweemolekyuli zehemoglobin.Basenokuthwala iiathom zeiron, ezihambisa ioksijini kuwo wonke umzimba njengehemoglobin.Ekubeni impahla ekrwada iyiplastiki, igazi elenziweyo lilula kwaye kulula ukuliphatha, alifuni kufakwa efrijini, linexesha elide elisemthethweni, linomsebenzi oncomekayo ngakumbi kunegazi lokwenyani lokwenziwa, kwaye akubizi mali ininzi ukulenza.
Ngophuhliso olukhawulezayo lwesayensi kunye nobuchwepheshe, iiplastiki ezintsha ziyaqhubeka ukubonakala.Iimpawu zokugquma, ukumelana nobushushu kunye nokumelana nomlilo kwezinye iiplastiki zobunjineli eziphezulu kunye neekhompawundi zibaluleke kakhulu.Ukongeza, ukukhuselwa kwendalo kunye nokonakala kuye kwaba yinto ebalaseleyo kwiiplastiki ezintsha.
