Polymer Composites with Biodegradative Properties

Polymer Science, Series D, 2019
The results of experimental studies of the mechanical and operational properties of carbon fiber when introduced with biologically active filler, in our case, bifidobacterin, are presented. It was found that, at a content of biologically active filler of up to 4%, the rate of biodegradation processes increases and the mechanical characteristics ...

Biodegradation of composite materials

International Biodeterioration & Biodegradation, 1996
Fiber-reinforced polymer composites were examined for susceptibility to microbiologically-influenced degradation. Composites, resins, and fibers were exposed to sulfur/iron-oxidizing, calcareous-depositing, ammonium-producing, hydrogen-producing, and sulfate-reducing bacteria (SRB) in batch culture.

Biodegradation of Bagasse Fiber Reinforced Biodegradable Composites

Key Engineering Materials, 2007
Biodegradable composites made from bagasse fiber and biodegradable resin were prepared and the biodegradation were investigated by the soil burial test in terms of the effects of fiber content, alkali treatment to bagasse fiber and different soil. The biodegradable resin showed some extent biodegradation.

Analysis of a biodegradable composite for bone healing

Journal of Biomedical Materials Research, 1996
A degradable L-PLA/calcium carbonate composite made of interconnecting phases was examined. This structure was used both to slow the degradation rate and to reduce the brittleness of the ceramic. Both in vitro and in vivo degradation studies were performed.

Composite biodegradable materials based on polyhydroxyalkanoate

Applied Biochemistry and Microbiology, 2010
Conditions for the processing and mixing of biodegradable polymers at temperatures less than their thermal destruction (130-150 degrees C) using standard equipment have been identified. The structure of the polyhydroxybutyrate/valerate (PHB/V) copolymer has been revealed and peculiarities of the crystal phase formation at different monomer ratios have ...

Biodegradable composites with aligned hydroxyapatite nanoneedles

Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2012
AbstractWe prepared an anisotropic bone graft composite to mimic the hierarchical structure of the natural bone in which aligned hydroxyapatite (HA) nanocrystals deposit along collagen fibers. To approach the modulus and strength of the bone, we incorporated synthesized HA nanoneedles and melt drawn poly(L‐lactic acid) fibers in our composite as ...

Composites of Wood and Biodegradable Thermoplastics: A Review

Polymer Reviews, 2017
This paper is an overview of current understanding in the areas of composites made from biodegradable thermoplastics and wood fillers. The review finds that the composite properties depend on the type of wood filler, the choice of polymer matrix, the wood filler content, the compatibilization technique used and the processing parameters.

The Development of Thermostatically Biodegradable Composite

Key Engineering Materials, 2021
The purpose of this research is to develop a new type of environmentally friendly container which has thermostatic effect and is biodegradable. This study is based on polylactic acid (PLA) and maleic anhydride grafted polybutylene succinate (MAPBS). Subsequently, the diatomite which adsorbed polyethylene glycol (PEG) was added to prepare a thermostatic
