Feem ntau siv surfactants yog cov khoom hnyav molecular uas muaj qhov hnyav ntawm ntau pua. Nrog rau ntau lub ntsiab lus kub xws li kev txhim kho cov roj rov qab Cov kev tshawb fawb tob txog cov neeg nqa tshuaj thiab tswj kev tso tawm, lom simulation, polymer LB zaj duab xis, cov ntaub ntawv kho mob polymer (anticoagulant), pleev xim polymerization, thiab lwm yam, tau nce ntau yam thiab kev ua haujlwm siab rau surfactants. Surfactant polymer tebchaw tau dhau los ua kom pom tseeb.
Cov khoom uas muaj qhov hnyav molecular ntawm ntau txhiab lossis ntau dua thiab cov dej num saum npoo feem ntau hu ua siab molecular hnyav surfactants. Zoo ib yam li cov surfactants zoo tib yam, tsis muaj cov txheej txheem kev faib tawm rau polymer surfactants. Raws li kev faib tawm ntawm qhov hnyav molecular hnyav surfactants raws li lawv cov ionicity hauv dej, lawv tuaj yeem muab faib ua anionic, cationic, zwitterionic, thiab nonionic hom. Raws li seb micelles tau tsim hauv cov tshuaj, nws tuaj yeem muab faib ua xab npum thiab dej-soluble polymer surfactants.
Polysoap
Feem ntau ntawm cov xab npum yog them, zoo ib yam li polyelectrolytes. Qhov tseeb, feem ntau cov xab npum yog cov khoom ntawm kev hloov kho hydrophobic ntawm polyelectrolytes thiab feem ntau insoluble hauv dej. Tam sim no muaj ntau hom tshuaj ntxuav tes (qhov twg R sawv cev rau cov saw ntev alkyl):
Dej soluble polymer surfactant
Polymer surfactants uas tsis tsim micelles hauv kev daws yog feem ntau dej-soluble polymer surfactants. Raws li lawv cov peev txheej, lawv tuaj yeem muab faib ua peb pawg: ntuj, semi hluavtaws, thiab hluavtaws polymer surfactants.
Ntuj polymers xws li ntau hom ntoo pos hniav, starches, microbial fermented polysaccharides, thiab lwm yam;
Semi hluavtaws polymers yog ntau yam polymers tau los ntawm kev hloov kho cov hmoov txhuv nplej siab, cellulose, thiab protein, xws li cationic starch, methyl cellulose, thiab lwm yam;
Synthetic polymers yog tau los ntawm polymerizing monomers muab los ntawm petrochemicals, xws li polyacrylamide derivatives, polyacrylic acid, thiab lwm yam.
Classification ntawm Polymer Surfactants
Raws li lawv cov ionicity hauv dej, lawv tuaj yeem muab faib ua anionic, cationic, zwitterionic, thiab non-ionic hom.
Anionic polymer surfactant
(1) Hom carboxylic acid hom polymers suav nrog polyacrylic acid thiab nws cov copolymer, butenoic acid thiab nws cov copolymer, acrylic acid maleic anhydride copolymer, thiab lawv cov khoom saponified ib nrab.
(2) Hom polymers ntawm sulfate ester hom muaj xws li:
(3) Sulfonic acid hom
Qee cov sulfonated polystyrene, benzenesulfonic acid formaldehyde condensate, naphthalene sulfonic acid formaldehyde condensate, sulfonated polybutadiene, thiab lwm yam. Lignosulfonate kuj yog sulfonic acid hom polymer surfactant. Hom sulfonic acid raws li polymer surfactants muaj xws li:
Cationic polymer surfactant
Amine ntsev los yog polyamines xws li polyethyleneimine, polyvinylpyrrolidone, polymaleimide, thiab lawv cov derivatives. Cov txheej txheem polymers muaj xws li:
(2) Quaternary ammonium ntsev
Xws li quaternized polyacrylamide, polyvinyl pyridine ntsev, polydimethylamine epichlorohydrin, thiab lwm yam. Quaternary ammonium polymer surfactants muaj cationic zog nyob rau hauv acidic, nruab nrab, thiab alkaline aqueous xov xwm. Cov khoom sawv cev muaj xws li:
Amphoteric polymer surfactant
Cov ntau yam muaj xws li acrylic vinyl pyridine copolymer, acrylic acid, cationic acrylic ester copolymer, amphoteric polyacrylamide, thiab lwm yam, xws li:
Tsis yog ionic polymer surfactants
Cov khoom tseem ceeb muaj xws li polyvinyl cawv thiab nws cov khoom esterified lossis acetalized, xws li hloov pauv polyacrylamide, maleic anhydride copolymer, polyacrylate, polyether, polyethylene oxide propylene oxide, dej-soluble phenolic resin, amino resin, thiab lwm yam.
Cov qauv thiab cov khoom ntawm Polymer Surfactants
Cov dej num ntawm cov khoom siv polymer surfactants nyob ntawm qhov morphology ntawm macromolecules hauv kev daws teeb meem, uas yog ze rau cov qauv tshuaj amphiphilic, muaj pes tsawg leeg, thiab qhov hnyav molecular ntawm macromolecules.
Thaiv hom surfactant
Ntau qhov thaiv hydrophobic ntu tau muab faib rau ntawm cov saw tseem ceeb ntawm macromolecules, thiab qhov ntev ntawm qhov tsim nyog ntawm hydrophobic hydrophilic sequence yuav tiv thaiv tus kheej ntawm hydrophobic segments (ua ib leeg-molecule micelles) los yog intermolecular aggregation (multi molecule aggregation)
Comb zoo li tus surfactant
Comb zoo li surfactants muaj qhov zoo ntawm kev npaj tau yooj yim thiab muaj ntau yam sib txawv. Surfactants tuaj yeem tau los ntawm homopolymerization lossis copolymerization ntawm ob leeg poj niam thiab amphiphilic monomers. Nyob ntawm txoj haujlwm ntawm hydrophobic thiab hydrophilic pawg, lawv nthuav tawm cov qauv tshuaj sib txawv.
Vim muaj cov pab pawg hydrophilic nyob rau sab chains, kev sib sau thiab kev koom ua ke ntawm hydrophobic ntu raug cuam tshuam. Txawm tias nyob rau hauv cov micelles twb tsim lawm, piv rau nruj packed core micelles, sab hauv kuj yog xoob thiab tseem muaj ib tug loj tus naj npawb ntawm dej molecules, yog li nthuav tawm cov dej num siab; Lub caij no, vim yog kev teeb tsa, amphiphilic ceg tuaj yeem cuam tshuam kev khi ntawm hydrophobic lub ntsiab chains tsim los ntawm methylene thiab methylene pawg, tso cai rau lawv los koom rau hauv interfacial adsorption.
Kev tshawb fawb tau pom tias txhua yam uas ua rau kom cov rigidity ntawm cov saw hlau molecular thaum tswj kev solubility yog qhov zoo rau kev ncab ntawm macromolecules hauv cov tshuaj thiab tuaj yeem txhim kho cov haujlwm saum npoo ntawm cov polymers.
Kev siv ntawm Polymer Surfactants
Daim ntawv thov hauv textile printing thiab dyeing kev lag luam
Polyether raws li polymer surfactants feem ntau yog siv los ua cov tshuaj detergents tsawg, emulsifiers, dispersants, defoamers, antistatic agents, wetting agents, printing thiab dyeing agents, thiab lwm yam; Polyvinyl cawv thiab lwm yam macromolecular compounds yog dav siv los ua thickeners thiab tiv thaiv colloids nyob rau hauv kev npaj cov tshuaj pleev ib ce thiab dyeing auxiliaries; Cellulose derivatives xws li carboxymethyl cellulose yog siv nyob rau hauv detergents li anti fouling agents; Lignosulfonate thiab phenolic condensate sulfonate yog siv los ua dispersants rau insoluble dyes.
