Optical and thermal characterizations of PMMA composites

الملخص EN

Thick composite films were prepared employing hand – lay-up method .

A definite quantity of PMMA ( 98%wt ) , fixed content ( 2% wt ) of rutile titanium dioxide TiO2 , gamma alumina ( ᵞ- Al2O3 ) and Zirconia powder ( ZrO2 ) , were added to polymer solution gradually and separately.

Optical constants were obtained of the prepared samples using spectrometer (UV- VIS).

The prepared composite samples were thermally characterized by differential scanning calorimeter ( DSC ).

We notice increasing value of glass temperature and differential heat capacity ( ΔCp ) for composites compared with pure PMMA .
