Ngwakọta ndị na-ejikọta Silane bụ ụdị ogige silicon organic nwere ihe abụọ dị iche iche nke kemịkalụ dị na molekul, nke a na-eji emeziwanye ike njikọ dị n'etiti polymers na ihe inorganic. Nke a nwere ike na-ezo aka na mmụba nke ezi nrapanye, yana mmụba nke wettability, Njirimara rheological, na ihe ndị ọzọ na-arụ ọrụ. Ngwakọta njikọ nwekwara ike inwe mmetụta na-agbanwe agbanwe na mpaghara interface iji kwalite oke oke n'etiti usoro organic na inorganic.
Ya mere,silane njikọ njikọA na-eji ya eme ihe na ụlọ ọrụ dịka nrapado, mkpuchi na inks, rọba, nkedo, fiberglass, cables, textiles, plastics, fillers, na ọgwụgwọ elu.

onye nnọchi anya njikọ silane..
Ngwaahịa ya kpochapụwo nwere ike ịnọchite anya usoro izugbe XSiR3, ebe X bụ otu ndị na-abụghị hydrolytic, gụnyere ndị otu alkenyl (karịsịa Vi) na otu hydrocarbon nwere otu ọrụ dị ka CI na NH2 na njedebe, ya bụ otu carbon arụ ọrụ; R bụ otu hydrolyzable, gụnyere OMe, OEt, wdg.
Otu ndị na-arụ ọrụ na-ebu na X na-adịkarị mfe imeghachi omume na otu ndị na-arụ ọrụ na polymer organic, dị ka OH, NH2, COOH, wdg, si otú ahụ jikọọ silane na organic polymers; Mgbe a na-eme ka mmiri na-arụ ọrụ na-arụ ọrụ, a na-agbanwe Si-R na Si-OH na ngwaahịa ndị dị ka MeOH, EtOH, wdg na-emepụta. Si OH nwere ike nweta mmeghachi omume condensation na akpịrị ịkpọ nkụ na Si OH na ụmụ irighiri ihe ndị ọzọ ma ọ bụ Si OH n'elu mkpụrụ osisi a na-agwọ iji mepụta njikọ Si O-Si, na ọbụna meghachi omume na ụfọdụ oxides iji mepụta njikọ Si O kwụsiri ike, na-enye ohere.silanejikọọ na inorganic ma ọ bụ metal ihe.
