Inkqubela phambili yoPhando kunye namaThandela eSelulosi eSebenzayo

Uphando malunga ne-cellulose esebenzayo yenze inkqubela phambili ebonakalayo kwiminyaka yakutshanje, eqhutywa yimfuno ekhulayo yezinto ezizinzileyo nezinokuhlaziywa kumashishini ahlukeneyo. I-cellulose esebenzayo ibhekiselele kwi-cellulose ephuma kwi-cellulose okanye i-cellulose eguquliweyo eneempawu ezilungiselelwe kunye nokusebenza ngaphaya kohlobo lwazo lwendalo. Nazi ezinye zenkqubela phambili yophando oluphambili kunye nethemba leselulosi esebenzayo:

1. Izicelo ze-Biomedical: I-cellulose derivatives esebenzayo, njenge-carboxymethyl cellulose (CMC), i-hydroxypropyl cellulose (HPC), kunye ne-cellulose nanocrystals (CNCs), iphononongwa kwizicelo ezahlukeneyo ze-biomedical. Ezi ziquka iinkqubo zokuhanjiswa kweziyobisi, ukunxitywa kwamanxeba, izikafula zobunjineli bezicubu, kunye ne-biosensors. I-biocompatibility, biodegradability, kunye neepropathi zeselulosi ezinokutya ziyenza ibe ngumgqatswa onomtsalane kwezo zicelo.
2. I-Nanocellulose-based Materials: I-Nanocellulose, kuquka i-cellulose nanocrystals (CNCs) kunye ne-cellulose nanofibrils (CNFs), ifumene umdla obalulekileyo ngenxa yeempawu zayo ezikhethekileyo zomatshini, umlinganiselo ophezulu, kunye nommandla omkhulu. Uphando lugxile ekusebenziseni i-nanocellulose njengokuqiniswa kwezinto ezidibeneyo, iifilimu, iimbumba, kunye ne-aerogels kwizicelo zokupakisha, ukuhluza, i-electronics, kunye nezixhobo zokwakha.
3. Izixhobo ezihlakaniphile neziphendulayo: Ukusebenza kwe-cellulose kunye neepolymers eziphendulayo okanye iimolekyuli zenza ukuba kuphuhliswe izinto ezihlakaniphile ezisabela kwi-stimuli yangaphandle njenge-pH, ubushushu, ukufuma, okanye ukukhanya. Ezi zixhobo zifumana izicelo ekuhanjisweni kweziyobisi, ukuva, ukusebenza, kunye neenkqubo zokukhululwa ezilawulwayo.
4. Ukuguqulwa koMphezulu: Iindlela zokuguqula umphezulu ziyaphononongwa ukuze zilungelelanise iipropati zomphezulu weselulosi kwizicelo ezithile. Ukuxhunyelelwa komphezulu, ukuguqulwa kweekhemikhali, kunye nokugquma ngeemolekyuli ezisebenzayo kuvumela ukuqaliswa kwemisebenzi efunwayo efana ne-hydrophobicity, iipropathi ze-antimicrobial, okanye ukunamathela.
5. Izongezo eziluhlaza kunye neeFillers: I-cellulose derivatives isetyenziswa ngakumbi njengezongezo eziluhlaza kunye nezihlunu kumashishini ahlukeneyo ukuze kuthathelwe indawo izinto zokwenziwa kunye nezingahlaziyekiyo. Kwii-polymer composites, iifayili ezisekelwe kwi-cellulose ziphucula iimpawu zemishini, ukunciphisa ubunzima, kunye nokuphucula ukuzinza. Zikwasetyenziswa njenge-rheology modifiers, thickeners, kunye nezinzisi kwiipeyinti, iingubo, izinto zokuncamathelisa, kunye neemveliso zokhathalelo lomntu.
6. Ukulungiswa kokusiNgqongileyo: Izixhobo ezisebenzayo zeselulosi ziphandwa ukuze kulungiswe usetyenziso lwendalo esingqongileyo, njengokucocwa kwamanzi, ukungcoliswa kongcoliseko, kunye nokucoca ukuchitheka kweoyile. Ii-adsorbents ezisekelwe kwi-cellulose kunye ne-membrane zibonisa isithembiso sokususa isinyithi esinzima, idayi, kunye nongcoliseko lwendalo kwimithombo yamanzi engcolileyo.
7. Ukugcinwa kwamandla kunye nokuguqulwa: Izinto ezithathwe kwi-cellulose zihlolwe ukugcina amandla kunye nezicelo zokuguqulwa, kubandakanywa i-supercapacitors, iibhetri, kunye neeseli zepetroli. I-electrode esekwe kwi-nanocellulose, i-separators, kunye ne-electrolytes zibonelela ngezibonelelo ezinje ngommandla ophakamileyo, i-porosity etyekayo, kunye nokuzinza kwendalo.
8. I-Digital kunye ne-Aditive Manufacturing: Izinto ezisebenzayo zeselulosi zisetyenziswa kwidijithali kunye neendlela zokuvelisa ezongezelelweyo, ezifana noshicilelo lwe-3D kunye noshicilelo lwe-inkjet. I-bioinks esekelwe kwi-cellulose kunye nezinto eziprintwayo zenza ukuba kwenziwe izakhiwo ezinzima kunye nezixhobo ezisebenzayo kunye ne-biomedical, i-electronic, kunye ne-mechanical applications.

Uphando nge-cellulose esebenzayo luyaqhubeka luqhubela phambili, luqhutywa kukufuna okuzinzileyo, okuhambelana nebhayoloji, kunye nezinto ezisebenza ngezinto ezininzi kwiinkalo ezahlukeneyo. Intsebenziswano eqhubekayo phakathi kwezemfundo, ishishini, kunye nee-arhente zikarhulumente kulindeleke ukuba zikhawulezise uphuhliso kunye nokuthengiswa kweemveliso ezisekelwe kwi-cellulose kunye nobuchwepheshe kwiminyaka ezayo.
