This is possible by adding solvent (water), dispersant, binder and plasticizer to ceramic powder. Water-based acrylic binders and plasticizers give ceramic films with suitable final properties like elasticity, strain, adhesion, homogeneity. Acrylic binders and plasticizers have been synthesized by emulsion polymerization with different ratios of ester monomers (MMA, EA) and different portion of acrylic acid (AA). The final properties of copolymers were varied by ratio of monomeric units. In the presence of water, the surface of zinc oxide is covered with amphoteric hydroxyl groups which react with the carboxylic groups of AA, that can be explained by multiplet-cluster model. Between charged monomers and metal ions are formed ionic pair or higher multiplets caused by electrostatic forces. Multiplets can further aggregate to form clusters. Binding between ceramic powder, i.e. metal ions and carboxylic groups was observed by FTIR and NMR spectroscopy"},{"@xml:lang":"sl","#text":"Pri izdelavi keramičnih polprevodniških elementov oblikujemo keramični prah (glavna komponenta je ZnO) v tanke plassti. Za ta namen pripravimo stabilne suspenzije keramičnega prahu z dodatkom topila (voda), dispergenta, veziva in mehčala. Akrilatna veziva in mehčala na vodni osnovi dajejo primerne keramične plasti z gladkimi površinami, ki so elastične, imajo primerno natezno trdnost in adhezijo ter so homogene. Akrilatna veziva ali mehčala smo sintetizirali z emulzijsko polimerizacijo z različnim razmerjem esterskih monomerov metilmetakrilata (MMA) in etilakrilata (EA), spreminjali pa smo delež akrilne kisline (AK). S spreminjanjem razmerja in količine monomernih enot smo vplivali na končne lastnosti kopolimerov. Karboksilne skupine AK reagirajo v vodnem mediju z ZnO oz. amfoternimi hidroksilnimi OH-skupinami, ki nastanejo na površini kovinskega oksida. Vezavo kovinskih ionov (?$Zn^{2+}$?) na karboksilne skupine (-COOH) v polimerni verigi lahko razložimo z modelom multiplet-klaster. Zaradi elektrostatskega privlačevanja med funkcionalnimi skupinami kopolimera in kovinskimi ioni najverjetneje nastanejo ionski pari, kvadropleti, seksapleti, večji multipleti in klastri, ki so agregati različnih ionskih multipletov. Vezavo keramičnega prahu oz. kovinskih ?$Zn^{2+}$? ionov na karboksilne skupine kopolimera smo opazovali z infrardečo (FTIR) in jedrsko magnetno-resonančno (NMR) spektroskopijo"},{"@xml:lang":"sl","#text":"Nadaljuje se kot: Materiali in tehnologije"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:doc-YTJ8JP63","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:doc-YTJ8JP63"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:doc-YTJ8JP63/b23f85a0-c18a-4900-a37c-431f54f1a27a/PDF"},"edm:rights":{"@rdf:resource":"http://rightsstatements.org/vocab/InC/1.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Inštitut za kovinske materiale in tehnologije"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:doc-YTJ8JP63/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:doc-YTJ8JP63"}}}}
