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.
