Opis:: Optical fiber technology is an important branch of science and technology, but also economy. Together with related disciplines it creates wider areas like optoelectronics and photonics. Optical fiber technology is developed in this country rather dynamically, proportionally to the available funds designed locally for research and applications. Recently this development was enhanced with considerable funds from European Operational Funds Innovative Economy POIG and Human Capital POKL. The paper summarizes the development of optical fiber technology in Poland from academic perspective during the period of last 2-3 years. Probably the digest is not very not full. An emphasis is put on development of optical fiber manufacturing methods. This development was illustrated by a few examples of optical fiber applications.

Opis:: The Conference on Optical Fibers and Their Applications, Nałęczów 2012, in its 14th edition, which has been organized since more than 35 years, has summarized the achievements of the local optical fiber technology community, for the last year and a half. The conference specializes in developments of optical fiber technology, glass and polymer, classical and microstructured, passive and active. The event gathered around 100 participants. There were shown 60 presentations of 20 research and application groups active in fiber photonics, originating from academia and industry. Topical tracks of the Conference were: photonic materials, planar waveguides, passive and active optical fibers, propagation theory in nonstandard optical fibers, and new constructions of optical fibers. A panel discussion concerned teaching in fiber photonics. The conference was accompanied by a school on Optical Fiber Technology. The paper summarizes the chosen main topical tracks of the conference on Optical Fibers and Their Applications, Nałęczów 2012. The papers from the conference presentations will be published in Proc. SPIE, including a conference version of this paper. The next conference of this series is scheduled for January 2014 in Białowieża.

Tytuł:: New thermoplastic polyurethane elastomers based on sulfur-containing chain extenders

Opis:: New thermoplastic polyurethane elastomers (TPUs) were synthesized by a one-step melt polyaddition from poly(oxytetramethylene) diol of M¯n = 2000 g/mol as the soft segment, 1,1’-methanediylbis(4-isocyanatocyclohexane) (HMDI, Desmodur W®), and 2,2’-[methanediylbis(benzene-4,1-diylmethanediylsulfanediyl)]diethanol (diol E) or 6,6’-[methanediylbis(benzene-4,1-diylmethanediylsulfanediyl)]dihexane-1-ol (diol H) as unconventional chain extenders. The effects of the kind and amount of the polymer diol and chain extender used on the structure and properties of the polymers were studied. The polymers were examined by Fourier transform infrared spectroscopy, gel permeation chromatography, thermogravimetric analysis, differential scanning calorimetry, Shore hardness and tensile testing. Both the adhesive and optical properties were determinated for a selected polymer. The obtained TPUs were amorphous, colorless, high-molar-mass materials. It was observed that the polymers with the diol E showed higher hardness and tensile strengths but smaller elongations at break than diol H-based ones. All of the polymers exhibited a relatively good thermal stability. Their temperatures of 5% mass loss were in the range 312-338°C.

Opis:: Artykuł stanowi przegląd literatury dotyczącej fotoaktywnych polimerów supramolekularnych, wktórych tworzeniu wykorzystano niekowalencyjne oddziaływania — wiązania wodorowe — między cząsteczkami azochromoforu ałańcuchami makrocząsteczek. Wpracy przedstawiono poszczególne rodzaje tego typu polimerów oraz wyniki badań ich fotoindukowanej anizotropii optycznej. Porównano azopolimery supramolekularne bazujące na wiązaniach wodorowych z: (i) układami zawierającymi chromofory zdyspergowane w matrycy polimerowej, (ii) układami otrzymanymi w wyniku oddziaływań jonowych oraz (iii) azopolimerami funkcjonalizowanymi. Omówiono także sposoby identyfikacji wiązań wodorowych w azopolimerach supramolekularnych.
The paper is a literature review on photoactive supramolecular polymers formed through noncovalent interactions, i.e. hydrogen bonds between azo chromophore molecules and macromolecule chains. The individual kinds of such polymers as well as the results of photoinduced optical anisotropy investigations related to them have been presented. The supramolecular azopolymers based on hydrogen bonds have been compared with (i) systems containing chromophores dispersed in polymer matrix, (ii) supramolecular systems based on ionic interactions and (iii) functionalized azopolymers. Additionally, the methods used for the identification of hydrogen bonds in supramolecular azopolymers were discussed.
