Ii-surfactants ezisetyenziswa ngokuqhelekileyo ziikhompawundi ezinobunzima bemolekyuli obubunzima obungamakhulu aliqela. Ngezihloko ezininzi ezishushu ezifana nokuphucula ukubuyiswa kweoli Uphando olunzulu malunga nomphathi weziyobisi kunye nokukhululwa okulawulwayo, ukulinganisa kwezinto eziphilayo, ifilimu ye-polymer LB, izixhobo zonyango ze-polymer (i-anticoagulant), i-polymerization ye-lotion, njl. Iikhompawundi ze-polymer ze-surfactant ziye zaba yingqwalasela.
Izinto ezinobunzima bemolekyuli obungamawaka aliqela okanye ngaphezulu kunye nomsebenzi womphezulu zidla ngokubizwa ngokuba zii-high molecular weight surfactants. Ngokufana nee-surfactants eziqhelekileyo, akukho sistim yokuhlela esemgangathweni yee-polymer surfactants. Ngokohlelo lwee-surfactants ezinobunzima obuphantsi bemolekyuli esekwe kubume be-ionic emanzini, zinokuhlelwa zibe ziintlobo ze-anionic, cationic, zwitterionic, kunye ne-nonionic. Ngokumalunga nokuba i-micelles yenziwe kwisisombululo, inokwahlulwa ibe isepha kunye ne-soluble polymer surfactants.
I-Polyseap
Uninzi lweesepha zihlawuliswa, zifana neepolyelectrolytes. Ngapha koko, iisepha ezininzi ziyimveliso yokuguqulwa kwe-hydrophobic ye-polyelectrolytes kwaye ayinyibiliki ngokubanzi emanzini. Okwangoku kukho iindidi ezininzi zeesepha ezenziweyo (apho i-R imele ialkyl yomxokelelwano omde):
I-polymer surfactant enyibilikayo emanzini
Ii-polymer surfactants ezingenzi micelles kwisisombululo zidla ngokuba zii-polymer surfactants ezinyibilikayo emanzini. Ngokwemithombo yabo, zinokwahlulwa zibe ziindidi ezintathu: zendalo, ze-semisynthetic, kunye ne-synthetic polymer surfactants.
Iipolima zendalo ezifana neentsini zomthi eziqhelekileyo, isitatshi, iipolysaccharides ezivundisiweyo ezincinci, njl.
I-semi-synthetic polymers ziipolymers ezahlukeneyo ezifunyenwe ngokuguqulwa kweekhemikhali zesitatshi, i-cellulose, kunye neprotheni, njenge-cationic starch, i-methyl cellulose, njl.
Iipolymers zokwenziwa zifunyanwa nge-polymerizing monomers evela kwi-petrochemicals, njenge-polyacrylamide derivatives, i-polyacrylic acid, njl.
Ukuhlelwa kweePolymer Surfactants
Ngokwe-ionicity yabo emanzini, banokuhlelwa kwiintlobo ze-anionic, cationic, zwitterionic, kunye ne-non-ionic.
I-anionic polymer surfactant
(1) Iipolima zohlobo lwe-carboxylic acid oluqhelekileyo ziquka i-polyacrylic acid kunye ne-copolymers, i-butenoic acid kunye ne-copolymers zayo, i-acrylic acid maleic anhydride copolymers, kunye neemveliso zazo ezinesaponified.
(2) Iipolima eziqhelekileyo zodidi lwe-sulfate ester ziquka:
(3) Uhlobo lwe-Sulfonic acid
Enye i-sulfonated polystyrene, benzenesulfonate acid formaldehyde condensate, naphthalene sulfonic acid formaldehyde condensate, sulfonated polybutadiene, njalo njalo. Iimpawu eziqhelekileyo ze-sulfonic acid esekwe kwi-polymer surfactants ziquka:
I-Cationic polymer surfactant
Iityuwa ze-amine okanye ii-polyamines ezifana ne-polyethyleneimine, i-polyvinylpyrrolidone, i-polymaleimide, kunye ne-derivatives yazo. Iipolymers eziqhelekileyo ziquka:
(2) Ityuwa ye-quaternary ammonium
Ezifana ne-quaternized polyacrylamide, ityuwa ye-polyvinyl pyridine, i-polydimethylamine epichlorohydrin, njl. Iimveliso ezimele ziquka:

Iindidi eziphambili zibandakanya i-polyvinyl alcohol kunye neemveliso zayo ezine-esterified okanye i-acetalized, ezifana ne-polyacrylamide eguquliweyo, i-maleic anhydride copolymer, i-polyacrylate, i-polyether, i-polyethylene oxide propylene oxide, i-phenolic resin enyibilikayo emanzini, i-amino resin, njl.
Ubume kunye neePropati zePolymer Surfactants
Umsebenzi womphezulu we-polymer surfactants uxhomekeke kwi-morphology ye-macromolecules kwisisombululo, ehambelana ngokusondeleyo kwi-amphiphilic chemical structure, umlinganiselo wokwakheka, kunye nobunzima be-molecular ye-macromolecules.
Ibhloki yodidi lwe-surfactant
Amacandelo amaninzi e-hydrophobic block hydrophobic asasazwa kwikhonkco eliphambili le-macromolecules, kwaye ubude obufanelekileyo bolandelelwano lwe-hydrophobic hydrophilic buya kuthintela ngokufanelekileyo ukudityaniswa kwezahlulo ze-hydrophobic (ukwenza ii-micelles ze-molekyuli enye) okanye ukuhlanganiswa kwe-intermolecular (i-aggregation yeemolekyuli ezininzi)
Ikhama emile surfactant
I-comb shaped surfactants ineenzuzo zokulungisa lula kunye neentlobo ezahlukeneyo. I-surfactants inokufunyanwa nge-homopolymerization okanye i-copolymerization yesini kunye ne-amphiphilic monomers. Ngokuxhomekeke kwisikhundla samaqela e-hydrophobic kunye ne-hydrophilic, abonisa izakhiwo zeekhemikhali ezahlukeneyo ze-branched.
Ngenxa yobukho bamaqela e-hydrophilic kumatyathanga asecaleni, ukudibanisa kunye nokudibanisa kwamacandelo e-hydrophobic kuthintelwe. Kwanakwii-micelles esele zenziwe, xa kuthelekiswa ne-micelles egxininiswe ngokuqinileyo, ingaphakathi likhululekile kwaye liqulethe inani elikhulu leemolekyuli zamanzi, ngaloo ndlela ibonisa umsebenzi ophezulu ophezulu; Okwangoku, ngenxa yokucwangciswa, amasebe e-amphiphilic anokuthintela ukubophelela kwamaketane aphambili e-hydrophobic ahlanganiswe ngamaqela e-methylene kunye ne-methylene, evumela ukuba bathathe inxaxheba kwi-adsorption interfacial.
Uphando lubonise ukuba nayiphi na into eyandisa ukuqina kwamakhonkco eemolekyuli ngelixa ukugcinwa kwe-solubility kunenzuzo yokwelula i-macromolecules kwisisombululo kwaye inokunyusa umsebenzi ongaphezulu weepolymers.
Ukusetyenziswa kweePolymer Surfactants
Isicelo kushicilelo olulukiweyo kunye neshishini lokudaya
I-polyether based polymer surfactants idla ngokusetyenziswa njengezinto zokucoca ezinogwebu ezisezantsi, ii-emulsifiers, dispersants, defoamers, antistatic agents, wetting agents, printing and dyeing agents, njl. Utywala bePolyvinyl kunye nezinye iikhompawundi ze-macromolecular zisetyenziswa ngokubanzi njengama-thickeners kunye ne-colloids ekhuselayo ekulungiseleleni ukuprintwa kwe-lotion kunye nokudaya abancedisi; I-cellulose derivatives efana ne-carboxymethyl cellulose isetyenziswa kwi-detergents njenge-anti-fouling agents; I-Lignosulfonate kunye ne-phenolic condensate sulfonate zisetyenziswa njenge-dispersants kwiidayi ezinganyibilikiyo.
