Polymérisation par transfert de chaîne réversible par addition fragmentationLa polymérisation radicalaire contrôlée par transfert de chaîne réversible par addition-fragmentation (en anglais Reversible Addition-Fragmentation Chain Transfer (RAFT)) est une technique de polymérisation radicalaire contrôlée.
Au même titre que la polymérisation radicalaire contrôlée par transfert d'atome (en anglais Atom Transfert Radical Polymerization (ATRP)) et la polymérisation radicalaire en présence de nitroxydes (en anglais Nitroxide Mediated Polymerization (NMP)), la polymérisation de type RAFT permet de synthétiser des polymères d'architecture contrôlée (polymères à blocs, étoiles, peignes, etc) de faible polydispersité et de haute fonctionnalité. Les applications de ces polymères sont, parmi d'autres, l'encapsulation de principes actifs de médicaments, la production de revêtements et peintures de nouvelles génération, la microfluidique, les tensioactifs, les adhésifs et les membranes.

Transparence (optique)Index. décimale : 668.4 Plastiques, vinyles Résumé : The gloss and haze of films can provide information about numerous functional material properties. With the control of optical properties method, they can be examined during production so that manufacturers are able to produce products of much higher quality and access new markets.

- Inspection with COP
- Evaluation of the angle-resolved lighting intensity
- Analyzing large data volumes
- Higher quality through optical inspection

OptiqueIndex. décimale : 667.3 Teinture et impression des tissus Résumé : Structural coloration is a quickly growing field, encompassing physical and photonic processes such as interference, diffraction, and scattering. In this study, we investigated the optical effects in the visible wavelength range, and in particular, the colour gamuts achievable with absorber–dielectric–metal sandwich structures. These chemical-free layered structures are highly tunable, easily scaled, optical cavities that are capable of generating remarkable colours whose properties are determined completely by material and structural parameters. We employed experimental and numerical strategies to demonstrate that each absorber spans a unique colour gamut, i.e. a subset of the full chromaticity space. While gamut overlap is observed between different absorber types, the gamut areas unique to each absorber occur at different hues of high excitation purity. A comprehensive understanding of how these colour gamuts develop and how different materials may be combined to expand larger subsets of the chromaticity space is required in order to maximize the variety of colours achievable with this system and elevate it into a ‘structural coloration technology’.

TomographieIndex. décimale : 668.4 Plastiques, vinyles Résumé : Injection molding of optical components is subject to strict requirements, including freedom from internal defects. Tomography analysis methods can identify even microdefects in the order of 20 µm. The main cause of these very small defects are gases that enter the melt either from the material or the environment. With new software, Engel intends to reduce gas inclusions during the processing of transparent plastics and ensures a consistent high melt quality. Note de contenu : - Making the smallest defects visible
- Customizable plasticizing is the key
- Variability in the melt compression
- Number of microvoids significantly lower
- Outlook : light guides and mechanically stressed parts
- Fig. 1 : Optical coherence tomography (OCT) provides two- and three-dimensional images from light-scattering samples with micrometer resolution
- Fig. 2 : Volume rendering of an OCT measurement (left) – width of the measurement range: 3 mm – allows the lens cross-section to be identified. XY layers are derived from this. The image right illustrates the microvoids after speckle removal
- Fig. 3 : Flow diagram: besides the backpressure generation by means of an axial advance of the screw (backpressure via screw position, left), pressure can also be generated by screw rotation
- Fig. 4 : The numbers indicate the number of microvoids detected per lens in each case. The diagram makes clear that this number can be significantly reduced with optimelt sequence and the additional pressure application
- Fig. 5 : With the use of optimelt sequence, the plastic lenses have significantly fewer microdefects (right).

SiliconesLes silicones, ou polysiloxanes, sont des composés inorganiques formés d'une chaine silicium-oxygène (...-Si-O-Si-O-Si-O-...) sur laquelle des groupes se fixent, sur les atomes de silicium. Certains groupes organiques peuvent être utilisés pour relier entre elles plusieurs de ces chaines (...-Si-O-...). Le type le plus courant est le poly(diméthylsiloxane) linéaire ou PDMS. Le second groupe en importance de matériaux en silicone est celui des résines de silicone, formées par des oligosiloxanes ramifiés ou en forme de cage (wiki).
Stabilité thermiqueIndex. décimale : 667.9 Revêtements et enduits Résumé : Silicone/titania hybrids for LED encapsulation were synthesized via hydrolysis and condensation reaction between tetrabutyl titanate and silica sol containing phenyl groups and long alkyl chains. Crack-free thick films (~1 mm) were fabricated by curtain painting. The hybrid films with different Ti contents were characterized by FTIR, UV–VIS, TGA/DSC, AFM, TEM, ellipsometer, etc. Results show that the hybrid films contain long alkyl chains which have high thermal stability against yellowing owing to the steric hindrance given by long alkyl chains. The hybrid films have high transmittance (≥98% in visible range) and high refractive index (1.591–1.681). In LED encapsulation, the silicone/titania hybrids with an RI of 1.605 increased the light extraction efficiency of bare blue LEDs by 19.4%.
