Public ISBD [article]  inIndustrial & engineering chemistry research > Vol. 50 N° 10 (Mai 2011) . - pp. 6109-6114 Titre : Immobilization of polymethyl methacrylate brushes on hydroxyapatite under molecular weight control Type de document : texte imprimé Auteurs : D. Tian, Auteur ; X. H. Chu, Auteur ; D. H. Yu, Auteur Année de publication : 2011 Article en page(s) : pp. 6109-6114 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Hydroxyapatite Immobilization Résumé : Polymethyl methacrylate (PMMA) brushes with a quantitative molecular weight (Mw) and low polydispersity index are synthesized via atom transfer radical polymerization and grafted onto the surfaces of hydroxyapatite (HA) that were modified with γ-methacryloxypropyl trimethoxysilane (MPTS). The structure and morphology of MPTS surface modified and furthermore PMMA grafted HA was mainly investigated by means of infrared spectrophotometry, X-ray diffraction, thermal gravimetric analysis, scanning electron microscope, and differential scanning calorimetry studies. It is found that polymer brushes are covalently attached to the HA surface under controlled Mw of PMMA segments without any structural deformation on the HA phase and exhibit grafting abilities for tuning properties of the composites.
