On the highway, accidents caused by tire blowers are not uncommon. How to reduce the number of tire blows to avoid major accidents has always been a concern. It was learned from Sichuan University that Wu Jinrong, a visiting professor at the school, and Cai Liheng, a postdoctoral researcher at Harvard University, have developed a new self-healing self-healing rubber that is comparable to natural rubber, or is Ekikkirizibwa okukozesebwa mu mipiira gy’emmotoka mu biseera eby’omu maaso. Nga tulina omupiira guno, omupiira guyinza okweddaabiriza ng’omupiira guli mu kutambula era nga gwa maanyi nga omupiira ogw’obutonde, okulongoosa ennyo obukuumi bw’emmotoka okutwalira awamu n’okuyamba okukendeeza ku bubenje bw’ebidduka. kigambibwa nti {7} ofiisi ya Harvard Technology Development ewaddeyo enkola ya patent okugikozesa era nga ya kunoonya mu ngeri ey’amaanyi okunoonya emikisa gy’okusuubula emikisa gy’okugifuga{{7}.
Okusinziira ku Wu Jinrong, abanoonyereza mu Harvard University’s John Paulson School of Engineering and Applied Sciences (mu kiseera kino ayitibwa SEAs) bakoze ekyuma ekiyitibwa hydrogel ekyewonya ekitumbula okuwona kwa bond ezikyukakyuka nga bassaamu amazzi.
The self-healing properties of dry materials such as rubber are difficult to achieve because they are made of polymers that are permanently covalently bonded. Although the covalent bonds are very powerful, once they are broken, they will never reconnect. To this end, Wu Jinrong and two colleagues, together with Harvard University postdoctoral researcher Cai Liheng, decided to develop a hybrid rubber with covalent bonds and reversible bonds. Because the two bonds are as miscible as oil and water, the researchers developed a molecular rope to bind them together, allowing them to mix evenly on the molecular scale, creating a transparent, tough, self-sufficient The more the rubber. "We used cross-linked, cross-linked, branched polymers to successfully bind hydrogen bonds and covalent bonds at the molecular scale. This technology has broad application potential, for Eky'okulabirako, mu kukola emipiira egy'okwewonya. tekyetaagisa kugikyusa amangu ddala ng'okwonoonebwa, ekiyamba okukendeeza ku bulabe bw'obubenje.".
It is understood that when the new "self-healing" rubber is subjected to tension, a mesh pattern appears, which is crack-like but does not completely crack, maintaining some fibrous joints. The mesh pattern disperses the tension and prevents the material from being severely broken that cannot be repaired. After the pulling force disappears, the rubber will return to its original shape and retain a tensile strength of approximately 30%.
