چکیده
In the present work plaster of paris containing polymer-based nanocomposites were prepared through chemical crosslinking and graft copolymerization of 2-hydroxyethyl methacrylate (HEMA) and acrylic acid (AA) on to polyvinyl alcohol (PVA) in the presence of ethylene glycol dimethacrylate (EGDMA) as crosslinker and potassium persulphate (KPS) and potassium metabisulphite (MBS) as redox components.  The structure of so prepared copolymers was confirmed by Fourier transform infrared (FTIR) spectroscopy while morphology was  examined using scanning electron microscopy (SEM) analysis.
The nanocomposites were found to show good mechanical properties as evident from the obtained experimental data. The maximum and minimum compressive strength of nanocomposites were found to be 29.5 (MPa) and 4.02 (MPa), respectively   whereas the maximum and minimum modulus were found to be 200 (MPa) and 34 (MPa). The water sorption behavior was found to be dependent on chemical composition of the nanocomposite matrix. The porosity of composite varied between 33 to 57%. The in vitroblood compatibility of the nanocomposite indicated that the adsorption of bovine serum albumin (BSA) varied from 0.015 to 0.047 mg g–1, the percentage haemolysis was between 12.3 to 23.7% and the weights of blood clot formed on the composite surfaces were found in the range 13 to 37 mg
