Nanocellulose ndiyo yakawandisa biomass sosi pasi. Iyo ine zvakanakira kushatisa zviri nyore, kudzoreredzwa, isiri-chepfu, yakachipa uye iri nyore kuwana, uye inotarisirwa kutsiva yechinyakare petrochemical zviwanikwa uye kushandiswa kugadzira akasiyana epamberi anoshanda zvinhu zvine kukosha kwakawedzera. Zvinoenderana nemaitiro ekugadzirira uye kunobva nanocellulose, nanocellulose inogona kukamurwa kuita zvikamu zvitatu: cellulose nanocrystalline (CNC), cellulose nanocellulose (CNF) uye bacterial cellulose (BC).

Nanocellulose zvinoshanda zvechiral photonics

Chirality inowanikwa kwese kwechisikigo uye inoita basa rakakosha muhupenyu sainzi nesainzi yezvinhu. CNC ndeye nanometer chiral photonic crystal zvinhu. Iyo chiral nematic liquid crystal phase chimiro cheCNC haingoshandiswe chete kugadzirira inoshanda firimu zvinhu zvine yakakwira mechanical zvimiro uye yakakosha optical zvimiro, asi zvakare inoshandiswa senge yakapfava yakapfava template yekukurudzira nanoparticles kuti igadzire zvinoshanda zvine chiral chimiro. Naizvozvo, chiral catalysis, chiral metamaterials, polarization encryption uye biosensing zvine kukosha kwekushandisa.

n makore achangopfuura, masayendisiti akagadzira zvine hungwaru zvakasiyana-siyana zvebiomimetic intelligent actuators zvichibva pane zvakapfava zvakatorwa kubva kune akasiyana mapolymer ekugadzira, seakajairika mahydrogel, liquid crystal elastomers uye chimiro chendangariro mapolymers, kutevedzera kana kutopfuura kutyaira kwezvipenyu. Nekudaro, izvi zvechinyakare zvepolymer-zvakavakirwa zvinhu zvinowanzogadzirwa kuburikidza nemaitiro akaomarara, zvinodhura uye zvakaoma kudzikisira kana kudzoreredza, izvo zvinogona kuisa mumwe mutoro panharaunda. Zvakakosha kucherechedza kuti biomimetic software madhiraivha akavakirwa pananocellulose akakwevera kutarisisa kwakawanda nekuda kwehukuru hwemakinika kuchinjika, yakakwirira kunyura hunyoro, kusimba kana eco-hushamwari, inogona kushandiswazve kana biodegradable uye biocompatibility.

Nanocellulose ine hombe yakananga nzvimbo, yakanakisa mechini kuchinjika, yakanaka kugadzikana kwekemikari uye kushamwaridzana kwezvakatipoteredza, uye mafiber anopindirana. Zviri nyore kugadzira porous chimiro cheion uye electron transport. Mapoka eHydrophilic anoshanda senge hydroxyl boka uye carboxyl boka akasungirirwa pamusoro pefiber, ine yakanaka kuchengetedza mwando mumhinduro ye electrolyte, zvichiita kuti zvakatorwa zvinoshanda zvinove netarisiro yakakura yekushandisa mumunda wekuchengetedza simba. Nanocellulose based functional materials haigoni kushandiswa chete sezvikamu zvakasiyana zvesimba rekuchengetedza magetsi, zvakadai se diaphragm, electrolyte, adhesive uye mutakuri. Panguva imwecheteyo, tembiricha yepamusoro carbonization, in situ makemikari polymerization uye electrochemical deposition nzira dzinogona kushandiswa kusanganisa nezvinhu zvemagetsi kuti uwane akakwenenzverwa nanostructures uye yakanakisa electrochemical zvinhu.

Nanocellulose inoshanda zvinhu zvebiomedical application

n iyo yakaoma mamiriro, iyo mechanical properties ye nanocellulose inofananidzwa nepfupa remunhu, asi mumamiriro ekunyorova, maitiro emuviri nemakemikari e nanocellulose akafanana neextracellular matrix. Zvichakadaro, mukuwedzera kune yakanakisa yemuviri uye makemikari zvivakwa, nanocellulose ine yakakwirira kuenderana nemamwe mapolymer kana anoshanda zvinhu, izvo zvinoita kuti nanocellulose zvinoshanda zvinhu zvive zvakanaka zvinoshanda uye tarisiro yakafara yekushandisa mumunda webiomedical.
