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.

Poly(methyl methacrylate) (PMMA) nanofibers are proved as good host matrix for various nanomaterials. Here, the possibilities offered by the process of electrospinning are exploited for the production of pure and structurally modified surface roughened and coaxial hollow PMMA electrospun nanofibers with unique advantages and surface characteristics, which is proved through various structural analyses. The host matrix nature of these pure and structurally modified surface roughened and coaxial hollow PMMA nanofibers to gold nanoparticles (AuNPs) are proved through different structural and morphological analyses. The host matrix nature of pure and structurally modified surface roughened and coaxial hollow PMMA nanofibers to AuNPs are compared with that of pure PMMA nanofibers by comparing their structural and optical properties. It is found here that, the surface roughened PMMA nanofibers act as better host matrix with more uniform distribution of particles and intensity enhancement than the pure and coaxial hollow PMMA nanofibers. Pure and coaxial hollow PMMA nanofibers show almost two times enhancement in intensity while the surface roughened PMMA nanofibers show almost five times enhancement in intensity after incorporating AuNPs. The host matrix nature of PMMA nanofibers is thus proved to be improved by making structural modifications on PMMA nanofibers in a simple and cost‐effective way. This makes them more suitable and adaptable in their applications. This superior property of surface roughened PMMA nanofibers over pure PMMA nanofibers can be used in all the application fields of PMMA nanofibers like optical works, catalytically supporting agents, antibacterial supporting systems and so on.

The present work deals with the studies of the host matrix nature of pure and structurally modified surface roughened and coaxial hollow electrospun poly(methyl methacrylate) (PMMA) nanofibers to lead sulphide (PbS) quantum dots. The various structural and molecular analyses conducted on these samples proved the advancements and structural modifications made in the properties of pure PMMA nanofibers by electrospinning and selective dissolution. The successful incorporation of the quantum dots to pure and structurally modified PMMA nanofibers and hence the host matrix nature of these nanofibers is proved by different spectral analyses of the samples. The coaxial hollow PMMA nanofibers are found to be the best host matrix among these PMMA nanofibers as proved by the optical studies of the samples. Photoluminescence analyses of the samples showed the influence of these quantum dots on the optical properties of PMMA nanofibers. It is observed here that, the quantum dots enhance the intensity of coaxial hollow PMMA nanofibers to about four times than its virgin form. The pure and structurally modified PMMA nanofibers incorporated with PbS quantum dots are proved to be efficient for the degradation of methylene blue dye where coaxial hollow PMMA nanofibers incorporated with PbS quantum dots is the best.

Electrospinning is the most favourable method for production of polymer nanofibres.In this study, we prepared a samarium β-diketonate complex that incorporated pure, surface-roughened and coaxial hollow poly(methylmethacrylate) (PMMA) nanofibres through electrospinning. The successful incorporation of this samarium complex into the PMMA nanofibres with different architectures was elucidated through various structural and morphological studies. Optical investigations as well as other characterization techniques for the pure, surface-roughened and coaxial hollow PMMA nanofibres before and after incorporating the samarium β-diketonate complex explained the host matrix nature of the PMMA nanofibres. Photoluminescence properties of the pure and structurally modified PMMA nanofibres were enhanced two or three times after incorporating the samarium complex into the fibre. Comparison of the optical properties between the pure and structurally modified PMMA nanofibres incorporating the samarium β-diketonate complex demonstrated the structural and optical improvements as well as the better host matrix nature of the surfaceroughened and coaxial hollow PMMA nanofibres over pure PMMA nanofibres for the samarium β-diketonate complex. These optical enhancements make these materials applicable for various optical devices.
