Ethyl cellulose hydrophilic ma ọ bụ hydrophobic

Ethyl cellulose bụ polymer sịntetik nke a na-ejikarị eme ihe na ụlọ ọrụ dị iche iche, gụnyere ọgwụ, nri, na nlekọta onwe onye. A maara ya maka ihe ndị na-emepụta ihe nkiri dị mma, nkwekọ dị elu na ihe ndị ọzọ, na ezigbo iguzogide kemịkalụ na ihe gburugburu ebe obibi. Otu n'ime ihe ndị bụ isi nke ethyl cellulose bụ hydrophobicity ya, nke bụ ihe atụ nke njikọ ya na mmiri.

Hydrophobicity bụ ihe onwunwe nke ihe na-akọwa ọchịchọ ya ịchụpụ ụmụ irighiri mmiri. N'ozuzu, ihe hydrophobic bụ ihe na-adịghị ike ma ọ bụ na-adịghị edozi ya na mmiri ma na-ejikọta ya na ụmụ irighiri mmiri hydrophobic ndị ọzọ. A na-ejikarị ama hydrophobicity site na ọnụnọ nke ndị na-abụghị polar ma ọ bụ obere polarity dị n'ụdị molekụla, dị ka agbụ hydrocarbon ma ọ bụ mgbanaka aromatic.

A na-ewere ethyl cellulose dị ka polymer hydrophobic n'ihi ọnụnọ nke ethyl dị iche iche na nhazi ya. Otu ethyl bụ ndị na-abụghị polar na hydrophobic, na ọnụnọ ha na-abawanye ụbara hydrophobicity nke polymer. Na mgbakwunye, ethyl cellulose nwere ogo dị ala nke nnọchi nke otu ethyl, nke na-enye aka n'ihu na agwa hydrophobic ya.

Otú ọ dị, enwere ike gbanwee hydrophobicity nke ethyl cellulose site n'ịgbanwe ogo nke nnọchi ma ọ bụ site na ịgbakwunye otu hydrophilic na nhazi polymer. Dịka ọmụmaatụ, iwebata otu hydrophilic dị ka hydroxyl ma ọ bụ carboxyl nwere ike ime ka hydrophilicity nke polymer dịkwuo mma ma melite solubility ya na mmiri. Enwere ike ịbawanye ogo nke nnọchi iji mee ka ọnụ ọgụgụ nke hydrophilic dị elu ma kwalite hydrophilicity nke polymer.

N'agbanyeghị hydrophobicity ya, ethyl cellulose ka na-ewere dị ka ihe bara uru maka ngwa dị iche iche, karịsịa na ụlọ ọrụ ọgwụ. Njirimara hydrophobic ya na-eme ka ọ bụrụ ihe mgbochi dị mma maka usoro nnyefe ọgwụ, ebe ọ nwere ike igbochi ntinye nke mmiri ma ọ bụ ihe ndị ọzọ hydrophilic n'ime ụdị usoro onunu ogwu. Nke a nwere ike inye aka chebe nkwụsi ike na ịdị irè nke ọgwụ ahụ n'ime ogologo oge.

Na nchịkọta, ethyl cellulose bụ polymer hydrophobic n'ihi ọnụnọ nke ethyl dị iche iche na-abụghị polar n'usoro ihe omimi ya. Agbanyeghị, enwere ike gbanwee hydrophobicity ya site n'ịgbanwe ogo nke nnọchi ma ọ bụ ịgbakwunye otu hydrophilic na usoro polymer. N'agbanyeghị àgwà hydrophobic ya, ethyl cellulose ka bụ ihe bara uru maka ngwa dị iche iche, karịsịa na ụlọ ọrụ ọgwụ.
