Structural and optical properties of synthesized poly(methyl methacrylate) (PMMA) and lanthanide $$\upbeta $$-diketonate complexes incorporated electrospun PMMA nanofibres for optical devices

Abstract

Fabrication of electrospun nanofibres is the glittering area of research because of their flexible characteristics and numerous applications in almost all walks of life and technology. Poly(methyl methacrylate) (PMMA) is one of the significant and interested synthetic polymers in the recent research because of their characteristic properties like higher environmental stability, resistance to attack by moulds and enzymes, commercial availability, easiness to handle, etc. In the present study, pristine PMMA nanofibres with diameters of 60-150 nm with 109 nm as the most distributed one are prepared by an electrospinning method using a binary solvent mixture. An enhancement in the intensity of visible photoluminescence emission is observed in PMMA nanofibres embedded with samarium and neodymium β-diketonate complexes. The morphological incorporation of samarium and neodymium β-diketonate complexes in PMMA nanofibres and material composition of the samples are examined by high resolution electron microscopy analyses. The amorphous nature and molecular bonding of pure PMMA nanofibres and incorporated fibre complexes are elucidated through structural and molecular analyses. The supreme optical absorptions and reemissions of samarium and neodymium β-diketonate complexes embedded in the pure PMMA fibre sample in the visible region indicate not only their application in lighting or display devices, but also as active materials in organic light emitting diodes for new era curved/rolled display devices.

Structurally modified poly(methyl methacrylate) electrospun nanofibers as better host matrix for noble metal nanoparticles

“…The UV–Visible analysis spectra of pure, surface roughened, coaxial hollow PMMA nanofibers and these nanofibers incorporated with gold nanoparticles are shown in Figure 12a–f. All the pure and structurally modified PMMA nanofibers show a broad absorption in the visible region as mentioned in previously published paper 32 and the UV–Visible spectra of these nanofibers show a significant change after incorporating AuNPs to them. The broadness of the absorption band is reduced to a great extent after incorporating AuNPs to the fibers.…”

“…PMMA is one of the main polymers in making electrospun polymer blend nanofibers with polymers like polyaniline, polystyrene etc., as evidenced in literature 26–31 . The host matrix nature of PMMA nanofibers to various nanomaterials has already proven in our own previous studies 32 and is available in literatures 4,33 . Noble metal nanoparticles like gold nanoparticles are also a matter of study in the research world out of their applications in various fields like sensors, 34,35 protein determination, 36 catalytic reductions, 37,38 medical treatments 13 etc.…”

“…Selective dissolution of PEO from PEO–PMMA nanofibers is carried out using deionized water at 60°C in both surface roughened and coaxial hollow nanofibers. The detailed procedure for the preparation of pure, surface roughened and coaxial hollow PMMA nanofibers and the analyses of each of them are given in our previously published papers 32,42 …”

“…PbS quantum dots have many applications in various fields like solar cells, LEDs, optical fibers, and so on 1,9 . PMMA nanofibers are also used in many optical devices 15,44–46 . The results obtained in the present study show that the pure and structurally modified PMMA nanofibers incorporated with PbS quantum dots are marked with PL intensity enhancement.…”

“…PMMA nanofibers are proved to be good host matrices for various nanomaterials as described in previous studies. 15 PMMA nanofibers catch our attention with their unique properties like transparency, commercial availability, environmental stability, resistance to molds and enzymes, and so on.
