Asayansi apanga polima kuti akhoza kanthawi kochepa makwinya

Akatswiri pa MIT apanga chimene chili khungu chachiwiri. Ndi zofewa, kusintha ndipo pafupifupi wosaoneka. Panopa, gulu la asayansi kuphunzira ntchito angathe kuchita zinthu zodzikongoletsera, kumene angakathandizidwe kuchotsa makwinya, matumba pansi maso kuchitira zinthu ndiponso rejuvenating pa maonekedwe wonse wa munthu. Zinthu zimenezi ndi sitepe yotsatira zochizira matenda khungu, kugwiritsira ntchito mankhwala osokoneza bongo, kapena kungoti chinyezi, - choncho anati phunziro Co-wolemba Daniel Anderson, Gwirizanani Professor wa Dipatimenti ya Chemical Engineering, mu mawu. anapezazo ndi m'magazini yotchedwa "Nature Zida".

ndi "khungu chachiwiri" n'chiyani?

Analenga asayansi zakuthupi ndi silikoni polima amene otsanzira khungu wathanzi. Iwo ali onse katundu makina ndi elasticity wa khungu achinyamata, komanso kukhala breathable ndi madzi. Imperceptible ❖ kuyanika kumatha makwinya ndi kupereka maonekedwe a unyamata maonekedwe - zonse popanda opaleshoni olanda ndi zipangizo kuti akhoza basi peel pa mapeto a tsiku ntchito.

Izi wosanjikiza wosaoneka amapereka chotchinga zipangitsa patsogolo zodzikongoletsera. Mwakulankhula kwina, ndi amapulumutsa mankhwala kwanuko m'madera amene amafunika chithandizo. Izi zimapangitsa abwino ntchito anthu.

Kodi ntchito?

mankhwala ntchito kaŵiri. Choyamba, munthu amagwiritsa ntchito kirimu colorless, imene ili polima anachokera ku siloxane a. Iwo aumbike mwa unyolo alternating pakachitsulo ndi mpweya mamolekyulu. Seŵenzetsani wachiwiri kirimu woyera mtundu, amene ndi pulatinamu chothandizira. Iwo imayendetsa ndi utomoni kupanga crosslinks akhala wowonda, zotanuka ndi amwazamwaza kuwala imene imapereka maonekedwe zambiri achinyamata. Zotsatira za ntchito limodzi la creams onse m'mawa ayenera lolimba tsiku lonse, ngakhale atadziŵa cheza ultraviolet ndi mvula.

mavuto kafukufuku

Msinkhu, khungu wotaya kulimba kwake ndi elasticity, ndipo ichi ndi chimodzi mwa zifukwa zimene iye kuyambira kuyang'ana achikulire. Kukula latsopano umalimbana kubwezeretsedwa kwa katundu izi. Pangani zinthu zimene amachita chimodzimodzi monga khungu, n'zovuta mokwanira, - anati phunziro Co-wolemba. Ambiri anayesera kuti achite izi, koma zipangizo analandira pa linanena bungwe, sanali wololera ndiponso yosavuta kugwiritsa ntchito, ndipo khungu sakumvetsa. Izi deta experimental akhoza sizikugwirizana ndi kayendedwe ka khungu ndipo sanathe kubwerera ku mtundu wapachiyambi.

yojambula A amene anapanga ofufuza akadali okha popanga zodzoladzola yekha. The polima watsopano wakhala bwinobwino anawayesa odzipereka anthu. Komabe, asayansi kufunafuna angamupeze angapo ofunsira Mwachitsanzo, mankhwala a chikanga, timadontho-timadontho kuchotsa, komanso makonzedwe m'dera la mankhwala ndi mankhwala.
