Njengezinto ezibalulekile, izinto ze-polymer zidlale indima enkulu emikhakheni eyahlukene yezimboni ngemuva kweminyaka ecishe ibe ngamashumi amahlanu yentuthuko.
Imboni yezinto ze-polymer ayigcini nje ngokuhlinzeka ngemikhiqizo emisha eminingi kanye nezinto zokukhiqiza izimboni nezolimo kanye nezingubo zabantu, ukudla, izindlu kanye nezokuthutha, kodwa futhi nokuhlinzeka ngezinto zokwakha nezisebenzayo ezisebenza kahle kakhulu zokuthuthukisa ubuchwepheshe obuphezulu.
Izinto ze-polymer ezisebenzayo ziyisifundo esiphumayo esihlanganisa izinhlobo ezahlukene zezifundo, okuhlanganisa i-organic chemistry, i-inorganic chemistry, i-optics, ugesi, i-structural chemistry, i-biochemistry, i-electronics, imithi kanye nezinye izifundo eziningi, futhi kuyinsimu yocwaningo esebenza kahle kakhulu ekhaya nakwamanye amazwe. Isizathu esiyinhloko sokuthi izinto ze-polymer ezisebenzayo zibe yindawo ebalulekile yocwaningo ezifundweni zezinto ekhaya nakwamanye amazwe ukuthi zine "imisebenzi" eyingqayizivele engasetshenziswa ukufaka ezinye izinto ezisebenzayo esikhundleni sazo futhi zithuthukise noma zithuthukise ukusebenza kwazo, zenze izinto ezisebenzayo zibe nezakhiwo ezintsha ngokuphelele.
Enye ingeyezitho zokwenziwa, njengezivalo zenhliziyo, izinso zokwenziwa, isikhumba sokwenziwa, ama-hernia patches, njll. Eyesibili ingeyezinto zokwelapha, njenge-sutures catheters zokuhlinzwa, izinto zokuhlola, izinto zokufakelwa, njll. Okwesithathu, isetshenziselwa izithasiselo zemithi Njengesithwali sokukhulula izidakamizwa, izinto zokuqondisa, njll.
Njengezinto zokuqala, ezisetshenziswa kakhulu futhi ezinkulu kakhulu ezintweni zokwelapha, ama-biopolymer ayinsimu ethuthuka ngokushesha, futhi abe yingxenye enkulu yezinto zokwelapha zesimanje, ngenxa yobubanzi bawo bezinto zokusetshenziswa, ikhono lokushintsha isakhiwo sawo ngokuklama kwama-molecule, ukusebenza okuphezulu kwezinto eziphilayo kanye nezakhiwo zezinto ezihlukahlukene. Zisetshenziswa kakhulu kulezi zindawo ezilandelayo:
Ukusetshenziswa kwezinto ze-polymer ekwelapheni amanzi
Izinto zokwakheka kwe-polymer ukusiza ubuchwepheshe bokwelapha amanzi Izinto zokwakheka kwe-polymer emkhakheni wemithombo yamanzi Ukusetshenziswa okubalulekile emkhakheni wemithombo yamanzi ubuchwepheshe bokwelapha amanzi e-membrane. Ukwelashwa kwamanzi e-membrane Ubuchwepheshe bokulungisa amanzi e-membrane buyindlela ephumelelayo yokuhlanza indle nokuvuselela imithombo yamanzi, ngokusebenza kahle kakhulu kokuhlukaniswa, ukusetshenziswa kwamandla aphansi, indawo encane, inqubo elula, ukusebenza okulula futhi kungabikho ukungcola. Ibonakala ngokusebenza kahle kokuhlukaniswa okuphezulu, ukusetshenziswa kwamandla aphansi, indawo encane, inqubo elula, ukusebenza okulula kanye nokungabikho kokungcola.
Izinto zokuqhuba ze-polymer embonini yezintambo nezintambo
Isetshenziswa njengesivikelo esihambisa amanzi kancane sezintambo zikagesi ukuthuthukisa ukusatshalaliswa kwamasimu kagesi; izintambo zikagesi kanye nekhebula likagesi elisebenzisa umhlabathi kanye nangaphandle komgoqo womhlaba; ikhebula lokushisa elizilawulayo elisebenzisa umoya kancane. Ingqikithi yezintambo zokufudumeza ezizilawulayo, njll. Ezinye izihlangu ezihambisa amanzi kancane zivame ukusetshenziselwa amalunga ekhebula kanye nokuqedwa. Itheyiphu yokuzinamathisela kagesi, ungqimba olungangeni manzi oluhlanganisiwe lwekhebula olunetheyiphu yamanzi yokumelana ne-semi-conducting, njll. nazo zingahlukaniswa njengezinto zokuhambisa amanzi ze-polymeric.
