The microbial degradation behavior of poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) (PHBHHx) and its compound with several polyesters such as poly(butylene adipate-co-telephtharate) (PBAT), poly(butylene succinate) (PBS), and polylactic acid (PLA) in seawater was tested by a biological oxygen demand (BOD) method. PHBHHx showed excellent biodegradation in seawater in this study. In addition, the...

Introduction Biodegradable stents have the potential to avoid long-term complications of conventional stents such as in-stent restenosis and late stent thrombosis, and could allow for a restoration of vasomotion and vessel growth which makes them suitable for e.g. paediatric applications [1]. To investigate the mechanics of this new type of stent via finite element simulations, we developed a n...

This article presents a thermal sintering method to fabricate porous bone tissue engineering scaffolds based on polycaprolactone (PCL), polylactic acid (PLA), and their composites. The mechanical properties, structure, biodegradability, biocompatibility of sintered were evaluated. showed porosity in the range 86–91% with pore size 75 m $$\mu$$ 400 . PCL/PLA composite Young’s modulus around 49 M...

The heavy-metal-free photocatalytic system, in which carbon nitride is coated on polylactic acid (PLA) as biodegradable plastic through a simple dip coating method, was used for dye decomposition under visible light irradiation. Solvent selection, solvent concentration, and the number of coatings were investigated to optimize conditions loading PLA. Carbon cannot be PLA water, but it can strong...

Owing to its biosynthetic and biodegradable properties, polylactic acid (PLA) is considered be a most promising biopolymer that could play crucial role as potentially environmentally friendly material for sustainable bioeconomy. However, long-life cycle indicates it cannot easily degraded in nature. Therefore, understanding the biodegradation mechanism of PLA important reducing impacts waste pl...

This study is aimed to investigate the effect of simultaneous incorporation cellulose nanocrystals (CNC) and silver nanoparticles (SN) on mechanical, biodegradability, water vapor permeability polylactic acid (PLA)-based films. PLA films their nanocomposites containing different levels CNC (0.333, 1 1.667 phr) SN (0.333 were prepared by solution casting method. was reacted with acetic anhydride...

In the field of governing our “Plastic Planet”, polylactic acid (PLA) has been considered to be a promising and ecologically friendlier alternative traditional petroleum-based plastics. However, PLA-based products degrade slowly in natural environment, likely resulting large accumulation PLA waste worldwide near future. Herein, we have incorporated artificially cultured diatom frustules (DFs) i...

We report on the fabrication of thin coatings based on polylactic acid-chitosan-magnetite-eugenol (PLA-CS-Fe3O4@EUG) nanospheres by matrix assisted pulsed laser evaporation (MAPLE). Transmission electron microscopy (TEM) and scanning electron microscopy (SEM) investigation proved that the homogenous Fe3O4@EUG nanoparticles have an average diameter of about 7 nm, while the PLA-CS-Fe3O4@EUG nanos...

Nanoscale carriers of active compounds, especially drugs, need not be spherical in shape. Worm micelles as blends of degradable polylactic acid (PLA) and inert block copolymer amphiphiles were prepared for controlled release and initial study of carrier transport through nano-porous media. The loading capacity of a typical hydrophobic drug, Triamterene, and the release of hydrophobic dyes were ...

This paper compares two types of polylactic acid (PLA) coating on AZ31 alloy obtained by dip and electrospinning. Both were loaded with gentamicin sulphate (GS) the drug-loading efficiency release assessed. A higher encapsulation GS was seen for (73% 49.53%, respectively) compared to nanofiber (65% 12.37%, respectively). Furthermore, antibacterial effect samples without assessed using Gram-nega...
