Qhov sib txawv tseem ceeb ntawm homochain thiab heterochain polymer yog tias homochain polymer muaj nws cov saw tseem ceeb ua los ntawm cov atoms ntawm tib cov tshuaj lom neeg thaum heterochain polymer muaj nws cov saw tseem ceeb ua los ntawm atoms ntawm cov tshuaj sib txawv.
A polymer yog ib qho macromolecular compound uas tsim los ntawm ntau qhov rov ua haujlwm txuas mus rau ib leeg los ntawm covalent tshuaj bonds. Cov no yog cov khoom hnyav nrog cov tshuaj lom neeg tshwj xeeb thiab lub cev. Muaj ntau txoj hauv kev los faib cov ntaub ntawv polymer. Categorizing cov polymers raws li qhov xwm ntawm lub caj qaum muab peb ob pawg li homochain thiab heterochain polymers.
Homochain Polymer yog dab tsi?
Homochain polymer yog ib hom khoom siv polymer uas lub nraub qaum ntawm cov polymer yog ua los ntawm cov atoms ntawm tib cov tshuaj lom neeg. Thiab, lo lus no feem ntau siv rau inorganic polymers.
Daim duab 01: Homochain Polymer ua los ntawm Sulfur Atoms nyob rau hauv cov pob txha
Tsis tas li ntawd, inorganic polymers yog macromolecules ua los ntawm ntau qhov rov ua dua, thiab lawv tsis suav nrog cov pa roj carbon atoms hauv lawv cov caj qaum (cov saw tseem ceeb). Piv txwv li, polymeric sulfur muaj tsuas yog sulfur atoms nyob rau hauv lub caj qaum. E.g. polysilane.
Heterochain Polymer yog dab tsi?
Heterochain polymer yog ib hom khoom siv polymer uas lub caj qaum ntawm cov polymer yog ua los ntawm cov tshuaj atoms sib txawv. Feem ntau, muaj ob hom atoms teem nyob rau hauv ib tug alternating qauv.
Heterochain polymers tuaj yeem pom nyob rau hauv ntau hom raws li hauv qab no:
- Si-raws li heterochain polymers: Polysiloxane polymers nrog Si thiab oxygen atoms nyob rau hauv ib tug alternating qauv yog categorized rau hauv pawg no. Ntawm no, txhua lub hauv paus Silicon (Si-base) muaj ob qhov hloov pauv: methyl thiab phenyl pawg.
- P-raws li: Polyphosphazenes tau categorized rau hauv pawg no. Cov ntaub ntawv polymer no muaj phosphorous thiab nitrogen atoms ua cov pob txha ntawm cov khoom siv polymer. Ntawm no, P thiab N atoms nyob rau hauv ib qho kev sib hloov.
Daim duab 02: Heterochain Polymer nrog cov qauv hloov pauv ntawm Phosphorous thiab Nitrogen Atoms hauv pob txha. Qhov no yog P-based Heterchain Polymer.
- B-raws li: Polymers uas muaj cov pob txha nraub qaum nrog cov qauv hloov pauv ntawm boron thiab nitrogen yog cais raws li B-raws li heterochain polymers.
- S-raws li: Polythiazyls muaj lub nraub qaum ntawm leej faj thiab nitrogen atoms nyob rau hauv ib qho kev hloov pauv. Tsis zoo li lwm hom, cov polymers no tsis muaj lwm cov khoom siv uas txuas nrog rau cov pob txha.
Qhov txawv ntawm Homochain thiab Heterochain Polymer yog dab tsi?
Muaj ntau txoj hauv kev los faib cov ntaub ntawv polymer. Categorizing cov polymers raws li qhov xwm ntawm lub caj qaum muab peb ob pawg li homochain thiab heterochain polymers. Qhov sib txawv tseem ceeb ntawm homochain thiab heterochain polymer yog tias homochain polymer muaj nws cov saw tseem ceeb ua los ntawm cov atoms ntawm tib cov tshuaj, hos heterochain polymer muaj nws cov saw tseem ceeb ua los ntawm atoms ntawm cov tshuaj sib txawv. Cov piv txwv feem ntau ntawm homochain polymers yog polysilanes, thaum cov khoom siv heterochain polymer muaj xws li polysiloxanes, polyphosphazene, polythiazyls, thiab lwm yam.
Cov infographic hauv qab no qhia txog qhov sib txawv ntawm homochain thiab heterochain polymer.
Summary – Homochain vs Heterochain Polymer
Kev faib cov polymers raws li qhov xwm txheej ntawm cov pob txha caj qaum muab peb ob pawg xws li homochain thiab heterochain polymers. Qhov sib txawv tseem ceeb ntawm homochain thiab heterochain polymer yog tias homochain polymer muaj nws cov saw tseem ceeb ua los ntawm cov atoms ntawm tib cov tshuaj, hos heterochain polymer muaj nws cov saw tseem ceeb ua los ntawm atoms ntawm cov tshuaj sib txawv.
