Lawv tuaj yeem npaj tau los ntawm kev sib xyaw ob lub monomers, uas yog tom qab (thiab feem ntau ib txhij) polymerized thiab cross-linked (Fig. 1a), lossis los ntawm dissolving ib monomer hauv lub network polymer; tus qub ces reacted los ua tus thib ob interpenetrating network (Fig. 1b).
Dab tsi yog qhov sib cuam tshuam network hydrogel?
Ib qho kev sib txuas sib txuas (IPN) yog ib hom hydrogel uas suav nrog ob lossis ntau dua polymeric units hauv lub network uas cov polymers sib txuas nrog ib leeg [65, 66] ib. IPNs raug kho raws li "alloys" ntawm cross-linked polymers thiab cov tes hauj lwm no yog indivisible kom txog thaum cov tshuaj bonds puas lawm [67, 68].
Dab tsi yog ib qho kev sib cuam tshuam polymer network?
Semi-interpenetrating polymer network (SIPN): A polymer suav nrog ib lossis ntau lub network thiab ib lossis ntau dua linear lossis branched polymer (s) yam ntxwv los ntawm nkag mus rau ntawm qhov ntsuas molecular ntawm yam tsawg kawg ib qho ntawm cov tes hauj lwm los ntawm yam tsawg kawg qee qhov ntawm cov kab lossis cegmacromolecules.
Dab tsi yog networked polymers?
Network polymers yog cov khoom sib txuas siab heev uas qee qhovntawm atom valencies txaus siab los ntawm cov ntawv cog lus uas ua rau peb-seem (3D) qauv.
IPN resin yog dab tsi?
Ib interpenetrating polymer network (IPN) yog cov khoom uas muaj ob lub polymers, txhua yam hauv daim ntawv network. … IPN cov qauv muab cov khoom tshwj xeeb thiab xav tau rau cov txheej txheem resin ua ntej thiab tom qab polymerization.

Cuam tshuam lossis cuam tshuam li cas cuam tshuam kev sib txuas lus?
Txhua zaus peb tham lossis mloog, muaj tej yam uas nkag mus rau hauv txoj kev sib txuas lus meej-yam uas cuam tshuam rau tus neeg txais tau cov lus los ntawm tus xa. Qhov kev cuam tshuam no yog hu ua " noise," thiab muaj ntau hom suab nrov uas tuaj yeem ua rau cov lus raug txhais tsis raug .
Lub polymer twg muaj kev sib txuas ntawm kev sib txuas?
Ntawm no, los ntawm cov kev xaiv muab Nylon-6, 6 yog cov polymer uas muaj kev sib txuas ntawm amide. Yog li, nylons tseem hu ua polyamides vim lawv cov yam ntxwv amide pawg hauv cov pob txha caj qaum. Amide pawg nyob rau hauv nylon molecules yog heev polar, thiab tsim hydrogen bonding ib leeg .
Puas yog cov tog cuam tshuam lossis cov tog neeg cuam tshuam?
" Affected" txhais tau tias " cuam tshuam, tsim kev cuam tshuam rau, hloov pauv hauv ib txoj kev." "Effected" txhais tau tias "tua, coj los, tsim ib yam dab tsi." Koj puas tau cuam tshuam lossis cuam tshuam los ntawm qee yam?
Vim li cas kev sib txuas lus yog kev sib cuam tshuam?
Txhua tus neeg pom lwm tus tus cwj pwm thiab muab lub ntsiab lus rau qee qhov ntawm nws. Cov kev coj cwj pwm uas lub ntsiab lus raug muab los ua cov lus. … Hauv kev sib cuam tshuam, txhua yam koj ua lossis tsis ua yog sib txuas lus ib co lus .
Nyob rau hauv ib qho kev tsis sib haum xeeb pn kev sib tshuam cov kev sib tshuam tam sim no ntawm qhov sib npaug yog?
Nyob rau hauv qhov tsis ncaj ncees PN-kho qhov kev sib tshuam tam sim no ntawm qhov sib npaug yog zero, vim tias sib npaug tab sis cov neeg nqa khoom hla hla kev sib tshuam . Thaum pn kev sib tshuam tsis ncaj ncees qhov kev sib tshuam tam sim no ntawm qhov sib npaug yog?
