Abstract This article presents two highly fluorescent donor- π -acceptor (D-π-A) moiety containing an electron-donating carbazole and phenothiazine donors fused with electron-withdrawing pyrrolo-quinoline acceptor dyes, PQC and PQPT. We also discussed the polymerization and film-forming process of dye PQC and PQPT doped in poly (methyl methacrylate) (PMMA) and polystyrene (PS) polymer to find their optical applications in polymer-based technology. We investigated the fluorescent properties of dyes PQC and PQPT from 0.01 – 1 wt. % in poly(methyl methacrylate) (PMMA). We also investigated the changes in the spectrum shape and shift in wavelength with changes in poly(methyl methacrylate) (PMMA), polystyrene (PS), and TiO2 doped in polystyrene (PS/TiO2). The analysis of surface morphology of prepared polymer samples was done with the help of a scanning electron microscope. The thermal and photostability of synthesized dyes in poly (methyl methacrylate) (PMMA), polystyrene (PS), and TiO2 doped in polystyrene (PS/TiO2) were investigated to get detailed information owing to the application of fluorescent polymers in the field of optoelectronic, nanohybrid coatings in solar concentrators, etc.

The Difference

Two core-shell structure poly methyl methacrylate-caprolactam (PMMA-CPL) and poly methyl methacrylate-caprolactam-sericin (PMMA-CPL-SS) nanoparticles were synthesized by emulsion polymerization. A latex blending process was performed on preparation of natural rubber (NR) blends, NR/PMMA-CPL and NR/PMMA-CPL-SS. Transmission electron microscopy (TEM) images showed that PMMA-CPL and PMMA-CPL-SS nanoparticles covering on the surface of NR particles homogeneously. SEM, AFM, ATR-FTIR and DSC were used to compare the difference between NR/PMMA-CPL-SS and NR/PMMA-CPL. The results showed that addition of SS improved the smoothness and reduced the amount of incompatible particles on the surface of NR/PMMA-CPL-SS film. Due to the introduction of CPL and SS, the number of escaping particles on the surface of NR was decreased during film forming process and the Tg of NR shifted to a higher temperature. The results indicated that the interfacial adhesion and compatibility of PMMA and NR were improved. Mechanical testing showed that PMMA-CPL nanoparticles could improve the mechanical property of NR. When the content of PMMA-CPL-SS was 10%, the tensile strength of NR/PMMA-CPL-SS film was increased by 19.6% compared to NR/PMMA-CPL. Moreover, the NR/PMMA-CPL-SS film exhibited a higher hydrophilic property after modification with PMMA-CPL-SS nanoparticles.

Graphene-poly(methyl methacrylate) (GNS-PMMA) composites were prepared by two methods. Graphite oxide nanosheet-poly(methyl methacrylate) (GO-PMMA) composites were prepared of methyl methacrylate monomer and the presence of graphite oxide (GO). Then the GO-PMMA composites were reduced to graphene nanosheet-poly(methyl methacrylate) by using hydrazine hydrate. The obtained composites were characterized by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and Transmission electron microscopy (TEM). The composite exhibited conductivities in the 1.58×10-9-4.21 S/cm range, depending on the amounts of graphite oxide and PMMA.

Polymers have been adopted industrially in the manufacture of lenses for optical applications due to their attractive properties such as high hardness, high strength, high ductility, high fracture toughness, and also their low thermal and electrical conductivities. However, they have limited machinability and are therefore classified as hard-to-machine materials. This study conducts a critical review on the machining of various polymers and polymeric materials, with particular focus on poly (methyl methacrylate) (PMMA). From the review it was concluded that various machining parameters affect the output qualities of polymers and which include the spindle speed, the feed rate, vibrations, the depth of cut, and the machining environment. These parameters tend to affect the surface roughness, the cutting forces, delamination, cutting temperatures, tool wear, precision, vibrations, material removal rate, and the mechanical properties such as hardness, among others. A multi-objective optimization of these machining parameters is therefore required, especially in the machining of PMMA.

The increasing use of poly methyl methacrylate (PMMA), often replacing tempered glass, is a consequence of its high rigidity, practicality, lightness and transparency. However, current manufacturing standards in the polymer industry recommend specific tests on these materials. The present study aims to mechanically test the properties of poly methyl methacrylate (PMMA) material under conditions that simulate a much more aggressive environment than usual. Infrared spectroscopy (FTIR), thermogravimetric (TG/DTG) tests, Izod impact tests, and scanning electron microscopy (SEM) analysis were performed. The results showed that poly (methyl methacrylate) (PMMA) maintained its tensile mechanical properties up to 105°C. Regarding the impact tenacity, the temperature negatively influenced the performance of this polymer.
