Abstract
Blending of polymer with organic/inorganic material has given a new direction for developing novel materials. This is an easy and inexpensive method of modifying various properties of the individual materials and composites. The aim of the present work is an attempt to incorporate crystals in polymer host and investigate the effect, on optical properties of the of polymer- crystal combine. In this paper a novel technique of incorporating inorganic/organic crystal in a host polymer matrix is reported. Crystals of acetoacetanilide (AA) are grown in the host Poly Methyl Methacrelate (PMMA) by simple evaporation technique. The scanning electron micrograph (SEM) studies reveal the growth of Acetoacetanilide crystals of varying sizes and shapes (flakes) in prepared samples. The results are confirmed by various spectroscopic characterization studies such as X-ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FT-IR) and the UV-Vis spectroscopy. The investigations carried out, show a change in optical absorption band edge which is attributed due to change in band gap because of crystal sizes.
