Properties of Polylactic Acid Reinforced by Hydroxyapatite Modified Nanocellulose

Green nanocomposites of polylactic acid reinforced with isolated nanocellulose

Evaluation of Ibuprofen Release from Gelatin /Hydroxyapatite /Polylactic Acid Nanocomposites

Gelatin-hydroxyapatite-polylactic acid (PLA) nanocomposites were synthesized using five different formulations. The nanocomposites were loaded with ibuprofen and the amount of drug in the carriers was determined. X-ray diffraction (XRD) analysis was conducted before and after drug loading to ensure the presence of ibuprofen on the nanocomposites. Drug delivery was evaluated in phosphate buffere...

Tensile Properties of Hydroxyapatite Whisker Reinforced Polyetheretherketone

Polyetheretherketone (PEEK) was reinforced with 0-40 vol% hydroxyapatite (HA) whiskers using a novel powder processing and compression molding technique. A powder mixture was uniaxially pressed into a composite powder compact and compression molded into a flat composite bar using an open-channel die, such that the HA whiskers exhibited a preferred orientation along the length of the bar and ten...

EVALUATION OF ANTIBACTERIAL PROPERTIES OF POLYLACTIC ACID-POLYCAPROLACTONE-CONTAINING HYDROXYAPATITE AND ZINC OXIDE NANOPARTICLES IN HARD TISSUE ABSORBABLE SCAFFOLDS

Today, many people need to use bone grafts and implants because of damage to bone tissue. Due to the stimulation of the immune system after implantation, infection at the operation site is very common, which causes swelling and pain in the operation area. The use of zinc oxide nanoparticles reduces infection at the operation site and reduces the patient's need for antibiotics. In the present st...

Properties of polylactic acid composites reinforced with oil palm biomass microcrystalline cellulose.

In this work, polylactic acid (PLA) composites filled with microcrystalline cellulose (MCC) from oil palm biomass were successfully prepared through solution casting. Fourier transform infrared (FT-IR) spectroscopy indicates that there are no significant changes in the peak positions, suggesting that incorporation of MCC in PLA did not result in any significant change in chemical structure of P...
