Modification of Polyvinyl Alcohol to Increase Resistance to Moisture in MDF Composites
Original language description
A Macro defect free (MDF) composites are materials consisting of inorganic cement and organic polymer. These materials have extreme mechanical properties that far outperform other cementitious materials and can compete with both ceramic and metal materials. Their mechanical properties are given by the minimization of pores and macro defects in the material and at the same time by mechanical-chemical interactions between cement and polymer. However, it is the presence of the polymer phase that reduce the moisture resistance of MDF composites. The water molecules travel along the structure of the polymer chain to the internal structure of the MDF composite, where the polymer swells and the cement hydrates additionally. This creates internal stresses, secondary defects and loss of mechanical properties. This work aims to increase the resistance of MDF composites to moisture. This can be achieved by increasing the density of the polymer phase by crosslinking the polymer. Maleic anhydride was selected as t
