“…Some of these materials were tested, characterized and applied also for neutron optic purposes [62][63][64][65][66][67][68] and only recently nanodiamond polymer-composites were even designed for use in neutron optics. 38,[69][70][71][72][73] Some of the most important advantages of using NPCs are:…”

Photosensitive materials with ever-improving properties are of great importance for optical and photonics applications. Additionally, they are extremely useful for designing components for neutron optical devices. We provide an overview on materials that have been tested and successfully used to control beams of cold and very cold neutrons based on diffractive elements. Artificial gratings are generated and optimized for the specific application in mind. We discuss the needs of the neutron optics community and highlight the progress obtained during the last decade. Materials that have been employed so far along with their properties are summarized, outlining the most promising candidates for the construction of an interferometer for very cold neutrons.

“…Designing new polymeric materials is a huge practice to address the need for development. [1][2][3][4][5] Polymer composites are one of the most commonly practiced polymeric materials, which are prepared by polymers and some fillers such as inorganic fillers [calcium carbonate (CaCO 3 ), 6 silica (SiO 2 ), 7 multi-walled (MWCNT), 8 and single-walled carbon nanotubes (SWCNT), 9 boehmite, 10 nanodiamond, 11 graphite, 12 etc.] and organic fillers from plant and animal origins such as natural fibers [raw fibers, microcrystalline cellulose (MCC), [13][14][15] nanocrystalline cellulose (NCC), 14 etc.]…”

A biodegradable polymer, the poly(butylene adipate co‐terephthalate) (PBAT), was compounded with the microcrystalline cellulose (MCC) obtained from different sources (such as wheat stalk and rice husk powder) to prepare the polymer composites. The two components, here found to be compatible, as evidenced by the Fourier transform infrared (FTIR) spectroscopy and scanning electron microscopy (SEM). Further assessment of the compounded fibers with the organic solvent, the toluene, illustrated the nature of the wetting phenomena of MCC by PBAT. The SEM observation showed the wrapping of the PBAT layer onto the MCC phase after the removal of the polymer matrix. The FTIR spectrum showed the presence of the PBAT carbonyl peak on extracted fibers from the composite via solvent removal. It could be concluded that the PBAT could wet the MCC effectively in the composites suggesting the potential of enhancing their properties.Highlights A biodegradable polymer, the PBAT, melt‐mixed with plant‐based natural fiber. The fiber in composites was found to be wetted with the PBAT layer. H‐bonding between the CO group of PBAT and the OH group of fiber caused wetting. Raw, processed, and silane‐treated fibers showed similar wetting phenomena.

Very high contrast volume holographic gratings recorded in photopolymerizable nanocomposite materials

Volume holographic phase gratings possessing the saturated refractive index modulation amplitudes as large as 4.5×10−2 were recorded at a wavelength of 532 nm in a photopolymerizable nanoparticle-polymer composite (NPC) film dispersed with ultrahigh refractive index hyperbranched-polymer (HBP) organic nanoparticles. This prominent result was achieved by a combination of the HBP nanoparticles with triazine and aromatic ring units and an electron donor/acceptor photo-initiator system doped in an acrylate monomer blend with low viscosity. As a result, efficient mutual diffusion of HBP nanoparticles and monomer having their very large refractive index difference took place. Obtained results suggest a potentiality of our newly developed HBP-dispersed NPC gratings as efficient volume holographic optical elements for various photonic applications including wearable headsets for augmented and mixed reality.
