TECHNOLOGY OF HYBRID MODIFICATION WITH HUMIC ACIDS OF BROWN COAL HYDROXYPROPYLMETHYL CELLULOSE FILMS
نویسندگان
چکیده
The peculiarities of the technology hybrid modification lignite humic acids biodegradable films based on hydroxypropylmethylcellulose are considered. As a result conducted research, with antibacterial properties were obtained for first time. Hydroxypropylmethylcellulose Walocel brand was used production films, and citric acid (99.88%) according to GOST 3652 is as catalyst crosslinking polymer films. part structures modified different types actually determined by IR spectroscopy. study, regularities changes in time appearance mold within framework established. It also established that giving them allows preserve biodegradation. acids, while properties, biodegradation be at least 91% 6 months an optimal content 10% mass. Biodegradable bactericidal hydroxypropylmethylcellulose, lignite, terms their operational characteristics, superior known similar natural biopolymers can recommended manufacture packaging dry food products (bread, cereals, nuts, etc.) extended storage period.

متن کاملSynthesis, characterization and antibacterial assessment of SiO2-hydroxypropylmethyl cellulose hybrid materials with embedded silver nanoparticles
Antibacterial SiO2 hybrid materials based on tetraethyl orthosilicate (TEOS), hydroxypropylmethylcellulose (HPMC) and silver were prepared by the sol-gel method. The content of cellulose derivate was 5 wt% and the silver concentration varied from 0.5 wt% to 2.5 wt%. The amorphous nature, morphology and antibacterial behaviour were studied. Fourier transform infrared (FTIR) spectra of the hybrid...

The sorption properties of tetracycline were compared between a coal humic acid (CHA) and a soil humic acid (SHA) under various solution chemistry conditions. Structural characteristics of the two humic acids were quantified in detail by elemental analysis, solid-state (13)C nuclear magnetic resonance (NMR), acid-base titration, and Zeta potential measurement. The CHA consists primarily of poly...

Magnetic resonance imaging was used to study the diffusion of a water solution of hydrochloric acid (HCl) and sodium hydrochloride (NaOH) into hydroxypropylmethyl cellulose matrices. Polymer in the form of a cylinder was hydrated in a water solvent of pH = 2, 7, and 12 at 37◦C and monitored at equal intervals with a 300 MHz Bruker AVANCE. The spatially resolved spin–spin relaxations times and s...
