Development of masterbatches for poly (ethylene terephthalate) with improved resistance to CO2 permeation [PDF]

open access: yes, 2008
This research has investigated nanocomposite based masterbatches as routes to improve the CO2 retention properties of PET bottles. Masterbatches of different types of polyamide/clay, PET/clay, PET/nano-silica flakes and PET/divalent layered metal ...

ZrC SiC Materials from the Polymer-Derived Ceramics Route

open access: yes, 2011
International audienceA method to manufacture composites ZrC SiCp using a polymer-derived ceramic route for SiC is reported. The key point of this approach was the use of SiC precursor polymers synthesized from a vinylsilane monomer, to enhance organic ...

Grewia polysaccharide as a pharmaceutical excipient in matrix tablets [PDF]

open access: yes, 2011
Matrix-based tablets using different concentrations of grewia gum, and the model drug ibuprofen, were prepared using a wet granulation technique. Similar formulations were also prepared using HPMC, guar gum or ethyl cellulose as the polymer matrix.

Manufacture of ultra high modulus polymer fibres: the polymerization step

open access: yes, 1998
Polymers with a rodlike conformation can be spun into ultra high strength fibres which find applications in the manufacture of light weight composites, cables and ropes, and protective clothing, among others. The polymerization of such rodlike molecules,

Low-temperature process for manufacturing all polymer thin-film transistors

open access: yes, 2005
We report a low-temperature process to manufacture an all polymer thin-film transistor avoiding curing and annealing temperatures higher than 80°C. This aspect of energy efficiency directly supports the low-cost feature of organic devices in fabrication.

Assessing interfacial bonding behaviour between wood and thermoplastics in composite materials

open access: yes, 2018
To assess the complex interfacial structure within composite materials a new interface testing method has been developed which idealises the bondline between wood and polymerhg. It allows in-situ testing of varying polymers and substrates over a range of

Plasma-chemical modification of polymer materials for cardiovascular surgery in order to change their wettability

open access: yesИзвестия Томского политехнического университета: Инжиниринг георесурсов, 2019
Polymeric materials are characterized by low values of the surface energy; they are poorly wetted by solvents, and have low adhesion to different materials and other disadvantages. The relevance of the work stems from the need to develop specific surface
