Muri ubu bushakashatsi, filime zangiza ibinyabuzima zakozwe zishingiye kuri chitosani (CH) ikungahaye ku mavuta ya thimme yingenzi (TEO) hamwe ninyongeramusaruro zitandukanye zirimo okiside ya zinc (ZnO), polyethylene glycol (PEG), nanoclay (NC) na calcium.Chloride (CaCl2) no kuranga ubwiza bwa nyuma ya kale iyo ikonje.Ibisubizo byerekana ko kwinjiza ZnO / PEG / NC / CaCl2 muri firime zishingiye kuri CH bigabanya cyane umuvuduko wogukwirakwiza imyuka y’amazi, bikongerera imbaraga imbaraga, kandi bigashonga amazi kandi bikabora muri kamere.Byongeye kandi, firime zishingiye kuri CH-TEO zifatanije na ZnO / PEG / NC / CaCl2 zagize akamaro kanini mukugabanya kugabanya ibiro bya physiologique, kugumya gukomera kwinshi, acide titratable, no kubungabunga chlorophyll, kandi yerekanaga hepfo *, ibuza gukura kwa mikorobe., isura na organoleptic ya cabage ibikwa iminsi 24 ugereranije na LDPE nizindi firime zibora.Ibisubizo byacu byerekana ko firime zishingiye kuri CH zikungahaye kuri TEO ninyongera nka ZnO / CaCl2 / NC / PEG nuburyo burambye, butangiza ibidukikije, kandi nuburyo bwiza bwo kubungabunga ubuzima bwimyumbati iyo bukonje.
Ibikoresho byo gupakira bya sintetike ya polymeric bikomoka kuri peteroli bimaze igihe kinini bikoreshwa munganda zibiribwa kugirango harebwe ubuziranenge n'umutekano byibicuruzwa bitandukanye.Ibyiza byibikoresho gakondo biragaragara kubera koroshya umusaruro, igiciro gito nibintu byiza bya barrière.Nyamara, gukoresha cyane no kujugunya ibyo bintu bitangirika byanze bikunze bizarushaho gukaza umurego ikibazo cy’ibidukikije byangiza ibidukikije.Kuri iki kibazo, iterambere ryibidukikije byangiza ibidukikije byihuta mumyaka yashize.Izi firime nshya ntabwo zifite uburozi, ibinyabuzima bishobora kwangirika, birambye kandi biocompatible1.Usibye kuba idafite uburozi na biocompatible, izi firime zishingiye kuri biopolymers karemano zirashobora gutwara antioxydants bityo ntiziteze kwanduza ibiryo bisanzwe, harimo no kongeramo inyongeramusaruro nka phalite.Kubwibyo, insimburangingo irashobora gukoreshwa nkuburyo bushoboka bwa plastiki gakondo ishingiye kuri peteroli kuko ifite imikorere isa nogupakira ibiryo3.Muri iki gihe, biopolymers ikomoka kuri poroteyine, lipide na polysaccharide yatejwe imbere neza, ikaba ari uruhererekane rw'ibikoresho bishya byangiza ibidukikije.Chitosan (CH) ikoreshwa cyane mubipfunyika ibiryo, harimo polysaccharide nka selile na krahisi, kubera ubushobozi bwayo bwo gukora firime byoroshye, ibinyabuzima byangiza umubiri, umwuka mwiza wa ogisijeni hamwe n’amazi yo mu mazi, hamwe nicyiciro cyiza cya mashini ya macromolecules isanzwe., 5.Nyamara, antioxydants nkeya na antibacterial ubushobozi bwa firime za CH, zikaba arizo ngingo ngenderwaho za firime zipakira ibiryo bikora, bigabanya ubushobozi bwabo6, bityo molekile ziyongera zinjizwa muri firime za CH kugirango habeho amoko mashya kandi akoreshwa neza.
Amavuta yingenzi akomoka ku bimera arashobora kwinjizwa muri firime ya biopolymer kandi irashobora gutanga antioxydeant cyangwa antibacterial sisitemu yo gupakira, ifasha kwagura ubuzima bwibiryo.Amavuta yingenzi ya Thyme naya mavuta yize cyane kandi akoreshwa cyane kubera antibacterial, anti-inflammatory na antifungal.Ukurikije ibigize amavuta yingenzi, hagaragaye imiti itandukanye ya thimme, harimo thymol (23-60%), p-cymol (8-44%), gamma-terpinene (18-50%), linalool (3-4%) ).%) na carvacrol (2-8%) 9, ariko, thymol igira ingaruka zikomeye za antibacterial bitewe nibirimo fenol muri yo10.Kubwamahirwe, gushyiramo amavuta yingenzi yibimera cyangwa ibiyigize mubikorwa bya biopolymer bigabanya cyane imbaraga za mashini za firime za biocomposite zabonetse11,12.Ibi bivuze ko ibikoresho byo gupakira hamwe na firime ya pulasitike irimo amavuta yingenzi yibihingwa bigomba gukorerwa ubundi buryo bwo kunaniza imitunganyirize y’ibikoresho byo gupakira ibiryo.
