Ba injeniyeri bakoze ubuhanga bukomeye bwo hanze PDRC (passiyo yumunsi wo gukonjesha imishwarara) polymer itwikiriye icyuho cyikirere kuva kuri nanometero kugeza kuri minisikeli zishobora gukoreshwa nkimashini ikonjesha ikirere hejuru yinzu, inyubako, ibigega byamazi, ibinyabiziga ndetse nicyogajuru - ikintu cyose gishobora gusiga irangi.Bakoresheje uburyo bushingiye kubisubizo byo guhinduranya icyiciro kugirango baha polymer imiterere isa nifuro ifuro.Iyo ihuye nikirere, igipande cya polymer PDRC cyerekana urumuri rw'izuba kandi gishyuha kugirango ubushyuhe bugere munsi y'ibikoresho bisanzwe byubaka cyangwa nibidukikije. umwuka.
Hamwe n'ubushyuhe bwiyongera hamwe nubushyuhe bukabije bihungabanya ubuzima kwisi yose, ibisubizo bikonje bigenda birushaho kuba ingenzi.Iki nikibazo cyingenzi, cyane cyane mubihugu bikiri mu nzira y'amajyambere, aho ubushyuhe bwimpeshyi bushobora kuba bukabije kandi biteganijwe ko bwiyongera.Ariko uburyo busanzwe bwo gukonjesha, nkumwuka gutondeka, bihenze, koresha ingufu nyinshi, bisaba kubona amashanyarazi yiteguye, kandi akenshi bisaba ozone-igabanya cyangwa ikonjesha parike.
Ubundi buryo bwo gukonjesha imbaraga cyane ni PDRC, ibintu bigaragara hejuru yubukonje ubwabyo mugaragaza urumuri rwizuba hamwe nubushyuhe bwikirere mukirere gikonje.Niba hejuru ifite izuba ryerekana (R) rishobora kugabanya kwiyongera kwubushyuhe bwizuba, kandi hamwe nigipimo kinini cyimirasire yumuriro (Ɛ) irashobora kwagura ikirere cyo gutakaza ubushyuhe bwumuriro, PDRC ikora neza.Niba R na Ɛ biri hejuru bihagije, kabone niyo gutakaza ubushyuhe bwa net bizabaho ku zuba.
Gutezimbere ibishushanyo mbonera bya PDRC biragoye: ibisubizo byinshi byubushakashatsi biherutse biragoye cyangwa bihenze, kandi ntibishobora gushyirwa mubikorwa cyangwa gushyirwa hejuru kurusenge ninyubako zifite imiterere nuburyo butandukanye. Kugeza ubu, bihendutse kandi byoroshye gukoresha irangi ryera byabaye igipimo cya PDRC. Nyamara, imyenda yera isanzwe ifite pigment ikurura urumuri ultraviolet kandi ntigaragaze uburebure burebure bwumucyo wizuba ryizuba, kubwibyo imikorere yabo iringaniye.
Abashakashatsi ba Columbia Engineering bavumbuye ibintu byinshi cyane byo hanze ya PDRC polymer bifatanye na nanometero-kugeza kuri micron-nini yo mu kirere ishobora gukoreshwa nka firime ikonjesha ikirere kandi ishobora gusiga irangi no gusiga irangi hejuru yinzu, inyubako, ibigega byamazi, ibinyabiziga, ndetse n’ibyogajuru. . gutatanya no kwerekana izuba
