Novel silicon dioxide -based nanocomposites as an antimicrobial in poly (lactic acid) nanocomposites films
Objective(s): Due to nanocomposites antimicrobial properties, one of the most extensive usages of nano-products is in packing industry. Thus, the production of packages with nanotechnology can effectively prevent against a variety of microorganisms. In this study, the silicon dioxide nanoparticles the poly (lactic acid) PLA films on antimicrobial and permeability was investigated. Methods...

متن کاملEffect of Laser Surface Modification on the Crystallinity of Poly„L-Lactic Acid..
Crystallinity of semicrystalline polymers such as aliphatic homopolymer poly(L-lactic acid) (PLLA) affects their degradation and physical properties. In this paper, the effects of laser irradiation using the third harmonic of a Nd:YAG laser on the crystallinity, long-range order, and short-range conformations at the surface of PLLA films are investigated. The factors affecting the transformatio...
متن کاملLactic acid: New roles in a new millennium.
T study of lactic acid (HLa) and muscular contraction has a long history, beginning perhaps as early as 1807 when Berzelius found HLa in muscular fluid and thought that ‘‘the amount of free lactic acid in a muscle [was] proportional to the extent to which the muscle had previously been exercised’’ (cited in ref. 1). Several subsequent studies in the 19th century established the view that HLa wa...
متن کاملAntifungal activity of nano-composite films based on Poly Lactic Acid
Objective(s): Nanocomposite active packaging systems were used to prepare antimicrobial and antifungal properties. This study was to investigate the physical and antimicrobial activity of prepared films against three types of aflatoxin producing fungi Aspergillus Flavus. Material and methods: For investigating the effect of antibacterial nano-covers, the direct contact of 0, 1%, 3% and 5%...
