“…Additionally, it is exactly known that while the non-grafted TiO 2 nanoparticles were completely precipitated, the grafted nanoparticles, both AA-g-TiO 2 and LA-g-TiO 2 , were easily mixed in chloroform, and a uniform suspension was obtained. In other nanocomposite films, there were parallel outcomes reached by Bodaghi et al and Li et al (17,18).…”

“…PLA-based composite materials have been extensively used in tissue engineering and controlled release fields due to their excellent biocompatibility, biodegradability, and processability (12). As a synthetic polymer, PLA lacks the adequate mechanical strength essential for bone tissue engineering applications, and hence various approaches for improvements of its property have been carried out involving structural modification, blending polymers, and incorporation of nanoparticles to form nanocomposites (18). In this study, unmodified and modified nano-TiO 2 particles were incorporated into PLA bulk to improve its mechanical behavior.…”

“…Among these nanoparticles, the most common is titanium dioxide (TiO 2 ), which has been approved by the US Food and Drug Administration (FDA) (17). It has great antimicrobial properties, odor inhibition, biocompatibility, inertness, low toxicity, and high antibacterial properties (18).…”

Photocatalytic Oxidation of PLA/TiO2-Composite Films for Indoor Air Purification

“…In comparison with prior research, better results were obtained during this work. 46 However, a few clumps of TiO 2 particles were observed on the inner surface of the film with high dosages of TiO 2 . During the heating phase of the blown film method, aggregation of the TiO 2 particles could occur.…”

Preparation and characterization of polyvinyl alcohol/polylactic acid/titanium dioxide nanocomposite films enhanced by γ‐irradiation and its antibacterial activity

“…53 These strong oxidants could react with the cell wall, membrane, and intracellular components inside or outside the bacteria; and they could oxidize proteins, lipids, and result in a bactericidal effect. 54 Several reports have investigated the use of TiO 2 nanoparticles as powerful antibacterial agents against various pathogenic bacteria 55 for possible use in biodegradable polymer films and in antimicrobial materials for packaging. 56,57 Furthermore, similar results are observed with lactic acid cross-linked films, which showed good bacteriostatic properties against the pathogenic bacterial species S. aureus and could be utilized in medical and protective packaging applications.…”
