Lilemong tsa morao tjena, ho bile le tlhokahalo e ntseng e eketseha eatenyetsehang pepenenenglifilimi tse ka kobehang kapa tsa bōptjoa ka libopeho tse fapaneng ho khotsofatsa litlhoko tse fapaneng tsa indasteri le tsa theknoloji. Lifilimi tsena li fumane lits'ebetso liindastering tse kang lisebelisoa tsa elektroniki, lipontšo, lisele tsa letsatsi, le liphutheloana tse bohlale, har'a tse ling. Bokhoni ba lifilimi tsena ba ho inama ntle le ho lahleheloa ke ponaletso ea bona bo bohlokoa bakeng sa katleho ea bona lits'ebetsong tsena. Empa hantle-ntle lifilimi tsee li finyella ho tenyetseha hakaale joang?
Ho araba potso ena, re hloka ho hlahlobisisa mokhoa oa ho qaptjoa le ho etsoa ha lifilimi tsena. Lifilimi tse ngata tse pepeneneng tse feto-fetohang li entsoe ka li-polymers, e leng liketane tse telele tsa likarolo tse pheta-phetoang tsa limolek'hule. Khetho ea thepa ea polymer e phetha karolo ea bohlokoa ho khethollang ho tenyetseha le ho pepeseha ha filimi. Lisebelisoa tse ling tse tloaelehileng tsa polymer tse sebelisetsoang lifilimi tse pepeneneng tse pepenene li kenyelletsa polyethylene terephthalate (PET), polyethylene naphthalate (PEN), le polyimide (PI).
Lisebelisoa tsena tsa polymer li fana ka lisebelisoa tse ntle haholo tsa mochini, joalo ka matla a phahameng a tsitsipano le botsitso bo botle ba sebopeho, ha li ntse li boloka pepeneneng. Liketane tsa limolek'hule tsa polymer li tletse ka thata 'me li fana ka sebopeho se matla le se ts'oanang ho filimi. Botšepehi bona ba sebopeho bo lumella filimi ho mamella ho kobeha le ho bōptjoa ntle le ho senya kapa ho lahleheloa ke ponahalo.
Ntle le khetho ea thepa ea polymer, mokhoa oa ho etsa lihlahisoa o boetse o tlatsetsa ho feto-fetoha ha filimi. Hangata lifilimi li hlahisoa ka ho kopanya mekhoa ea extrusion le ho otlolla. Nakong ea ts'ebetso ea extrusion, thepa ea polymer e qhibiliha ebe e qobelloa ka lesoba le lenyenyane le bitsoang die, le le bōpang hore e be letlapa le lesesaane. Joale letlapa lena lea pholile ebe le tiisoa ho etsa filimi.
Ka mor'a ts'ebetso ea extrusion, filimi e ka 'na ea nka mohato o otlolohileng ho ntlafatsa ho fetoha ha eona. Ho otlolla ho kenyelletsa ho hula filimi ka litsela tse peli tsa perpendicular ka nako e le 'ngoe, e leng ho lelefatsa liketane tsa polymer le ho li hokahanya ka tsela e itseng. Mokhoa ona oa ho otlolla o hlahisa khatello ea maikutlo filiming, ho etsa hore ho be bonolo ho khumama le ho bōptjoa ntle le ho lahleheloa ke ponahalo ea eona. Tekanyo ea ho otlolla le tataiso ea ho otlolla e ka fetoloa ho finyella phetoho e lakatsehang filiming.
Ntho e 'ngoe e amang bokhoni ba ho koba ealifilimi tse pepeneneng tse tenyetsehangke botenya ba tsona. Lifilimi tse tšesaane li atisa ho fetoha habonolo ho feta tse teteaneng ka lebaka la ho fokotseha ha tsona ho hanyetsa ho kobeha. Leha ho le joalo, ho na le khoebo pakeng tsa botenya le matla a mochine. Lifilimi tse tšesaane li ka 'na tsa atisa ho taboha kapa ho phunya, haholo-holo haeba li tlas'a maemo a thata. Ka hona, bahlahisi ba hloka ho ntlafatsa botenya ba filimi ho latela litlhoko tse khethehileng tsa kopo.
Ntle le thepa ea mechine le ts'ebetso ea tlhahiso, ho pepeseha ha filimi ho boetse ho itšetlehile ka litšobotsi tsa eona tsa holim'a metsi. Ha leseli le kopana le bokaholimo ba filimi, le ka bonahatsoa, la fetisoa kapa la monngoa. E le ho finyella pepeneneng, lifilimi li atisa ho koaheloa ka likarolo tse tšesaane tsa lisebelisoa tse bonaletsang, tse kang indium tin oxide (ITO) kapa li-nanoparticles tsa silevera, tse thusang ho fokotsa ho bonahatsa le ho ntlafatsa phetiso ea leseli. Liaparo tsena li tiisa hore filimi e lula e le pepeneneng le ha e kobehile kapa e bōptjoa.
Ntle le ho tenyetseha le ho pepeseha ha tsona, lifilimi tse pepeneneng tse tenyetsehang le tsona li fana ka melemo e meng e mengata ho feta lisebelisoa tse thata tsa setso. Boima ba bona bo bobebe bo ba etsa hore ba tšoanelehe bakeng sa lits'ebetso moo ho fokotsa boima ba 'mele ho leng bohlokoa, joalo ka lisebelisoa tsa elektroniki tse nkehang habonolo. Ho feta moo, bokhoni ba bona ba ho ikamahanya le libaka tse kobehileng bo etsa hore ho be le moralo oa lisebelisoa tse ncha le tse bolokang sebaka. Mohlala,lifilimi tse pepeneneng tse tenyetsehangli sebelisoa libonong tse kobehileng, tse fanang ka boiphihlelo bo tebileng ba ho boha.
Keketseho e ntseng e eketseha ealifilimi tse pepeneneng tse tenyetsehange khothalelitse lipatlisiso le nts'etsopele lefapheng lena, ka bo-ramahlale le baenjiniere ba lekang ho ntlafatsa thepa ea bona le ho atolosa lits'ebetso tsa bona. Ba ntse ba sebeletsa ho nts'etsapele lisebelisoa tse ncha tsa polymer tse nang le maemo a bonolo le pepeneneng, hammoho le ho hlahloba mekhoa e mecha ea tlhahiso ho fihlela tlhahiso e theko e tlase. Ka lebaka la boiteko bona, bokamoso bo bonahala bo tšepisalifilimi tse pepeneneng tse tenyetsehang, 'me re ka lebella ho bona lits'ebetso tse ncha liindastering tse fapaneng.
Qetellong, ho tenyetseha ha lifilimi tse pepeneneng ho finyelloa ka ho kopanya lintlha, ho kenyelletsa khetho ea thepa ea polymer, ts'ebetso ea tlhahiso, botenya ba filimi, le litšobotsi tsa eona tsa bokaholimo. Lisebelisoa tsa polymer tse nang le thepa e ntle ea mochini li lumella filimi hore e mamelle ho khumama ntle le ho lahleheloa ke pepenene. Ts'ebetso ea tlhahiso e kenyelletsa extrusion le ho otlolla ho ntlafatsa ho feto-fetoha ha maemo. Liaparo le likarolo tse tšesaane li sebelisoa ho fokotsa ho bonahatsa le ho ntlafatsa phetiso ea leseli. Ka lipatlisiso le nts'etsopele e tsoelang pele, bokamoso balifilimi tse pepeneneng tse tenyetsehange shebahala e khanyang, 'me e ikemiselitse ho fetola indasteri le theknoloji ka litsela tse ngata.
