Chitosan grafted with poly(methyl-methacrylate) (PMMA) and adsorbed with kaolin functionalized as bioadhesive was prepared via emulsion polymerization technique and physiochemically characterized as a bone-graft substitute. The so prepared grafted bioactive bone cement (BBC) bionanocomposites (BNCs), chitosan-g-PMMA/kaolin, was characterized by Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD) analysis, field-emission scanning electron microscopy (FESEM) and thermogravimetric analysis (TGA). The water uptake, retention ability and the nanosize particle arrangement in the polymeric BBC-BNCs were studied along with the mechanical and biodegradation properties. These preliminary investigations of the BNCs will open the door for their use in bioadhesive bone-cement implants in the future.

More about this publication?
  • The Journal of Renewable Materials (JRM) publishes high quality peer reviewed original research on macromolecules and additives obtained from renewable/biobased resources. Utilizing a multidisciplinary approach, JRM introduces cutting-edge research on biobased monomers, polymers, additives (both organic and inorganic), their blends and composites. It showcases both fundamental aspects and new applications for renewable materials. The fundamental theories and topics pertain to chemistry of biobased monomers, macromoners and polymers, their structure-property relationship, processing using sustainable methods, characterization (spectroscopic, morphological, thermal, mechanical, and rheological), bio and environmental degradation, and life cycle analysis. Demonstration of use of renewable materials and composites in applications including adhesives, bio and environmentally degradable structures, biomedicine, construction, electrical & electronics, mechanical, mendable and self-healing systems, optics, packaging, recycling, shape-memory, and stimulus responsive systems will be presented.
