Fluorescent Polyimide Films Produced with Diatomite and Mesoporous Silica as Promising High-Tech Material

Due to their excellent properties, polymides (PIs) result promising as high-performance materials in different technological fields. In this research, both micron-sized tubular mesoporous silica (mSiO2) and double-tube diatomite particles with cadmium sulfide quantum dots are prepared by chemical deposition method. A cluster of type fluorescent is self-assembling carbon (CDs) on the inner surface above materials. Then, a polyimide film uniform dispersion particles. The study properties becomes then mandatory evaluate possible application perspectives. Therefore, after synthesizes, all samples were investigated term structure, microstructure fluorescence infrared spectroscopy, X-ray diffraction, scanning electron microscopy spectrophotometry. Fluorescence performance diatomite-based (diatomite@CdS@CDs) results not good mSiO2-based (mSiO2@CdS@CDs) ones; mechanical composite deteriorate content inorganic component increases. PI/mSiO2@CdS@CDs 7.6 times PI/diatomite@CdS@CDs ones.
