“…Nevertheless, biocomposites of these polymers with calcium orthophosphates showed a good biocompatibility both in vitro and in vivo [94,[340][341][342][343][344][345]. Both bioactivity and mechanical properties of these biocomposites can be tailored by varying the volume percentage of calcium orthophosphates.…”

Polyhydroxybutyrate Composites with Random Mats of Sisal and Coconut Fibers

Biodegradable polymeric composites using natural fibers have been investigated aiming to mitigate environmental impacts. In this paper, polyhydroxybutyrate (PHB) composites obtained using random mats of sisal and coconut fibers by compression molding in a hydraulic press, and the fiber content varied between 10% and 15% relative to the weight of the polymer. Thermal analyses were performed such as Differential Scanning Calorimetry (DSC) and Thermogravimetric Analysis (TGA). Flexural and tensile tests were performed before and after conditioning in climate chamber with temperature and moisture. The results of thermal analysis show that the thermal stability of the materials remained, both PHB without fiber as for composites with natural fibers mats. The results of mechanical tests indicated that the PHB without fibers and composites showed similar flexural strength values, while the results of the tensile test PHB without fibers showed resistance to higher tensile composite.

“…Studies have described formation of apatite crystals on the surface of PHB/HA composites after immersion in SBF. Ni and Wang [22] evaluated the effect of HA on the bioactivity of PHB using HA amounts of 0, 10, 20 and 30 vol% HA. It was observed formation of small crystals after 1 day immersion and more near-spherical crystals were observed on the specimen after 7 days immersion.…”

Production of polyhydroxybutyrate and hydroxyapatite (PHB/HA) composites for use as biomaterial

et al. 2017

The composite materials using polyhydroxybutyrate as matrix and hydroxyapatite as reinforcement (PHB/HA) were produced by molding, using pressing at 100 MPa and 165 °C for 30 min. The amount of filler was varied from 0 to 20 wt% to evaluate the effect of the HA particles on mechanical properties and the bioactivity of the composites. The increase of the HA amount reduced the compressive strength of the composites nearly 20% while bending strength reduced nearly 30%. However, the bioactivity after 14 days immersion in SBF was improved with the increase of HA amount, with formation of apatite layer on the surface of the PHB/HA composite.
