Composition polysiloxane based coatings are currently the only viable commercial alternative of the toxic biocide containing antifouling paints. Oil incorporation improves the foul-releasing ability of the polysiloxane coatings. The impact of non-reactive, different molecular mass, both siloxane and fluorinated oil on the biofilm formation onto developed by us polysiloxane composition coating i...

The handling of vinyl polysiloxane (addition silicone) impression putties with latex gloves is said to interfere with the setting of these impression materials. The aim of this study is to evaluate the effect of handling techniques on the setting of vinyl polysiloxane impression putties using several types of gloves. The setting of these materials was evaluated by means of an elasticimeter. Fou...

The authors demonstrate the production of low loss enhanced index contrast waveguides by reactive ion etching of IPGTM polysiloxane thin films. The use of a silica mask and CHF3 /O2 etch gas led to large etch selectivity between the silica and IPGTM of !20 and etch rates of !100 nm /min. This work indicates that compact optical circuits could be successfully fabricated for telecommunication app...

The coemulsification method suitable for the formulation of microcapsules of n-eicosane coated with a polysiloxane is developed. This method allows to synthesize core-shell microcapsules of paraffin which have the shape of spheres or distorted spheres and are designed for the use as phase change materials. The microcapsules are formed in aqueous phase by the precipitation of n-eicosane together...

Superhydrophobicity has gained extensive interest in academia and industry. One of the most facile ways of creating superhydrophobic surfaces is the surface-initiated synthesis of 1D polysiloxane nanostructures known as silicone nanofilaments. However, physicochemical details of their synthesis process remain a puzzle, and studies so far have fallen short in explaining the ways in which the 3D ...

The aim of this study was to regulate fluoride release from restorative resin containing NaF using N-(beta-aminoethyl)-gamma-aminopropylmethyldimethoxysilane (AMMS) and evaluate factors that regulate fluoride release from the resin. ESCA analysis, FT-IR measurements along with SEM observations demonstrated that a polysiloxane layer was formed on the surface of NaF treated with AMMS. Bis-GMA/TEG...

Two main issues for the wide application of polymer-matrix nanocomposites need to be addressed: cost-effective processing of high-performance nanomaterials, and fundamental understanding of the nanofiller-polymer interaction related to property changes of nanocomposites. To fabricate inexpensive and robust carbon nanofibers (CNFs) by the electrospinning technique, an organosolv lignin for repla...

The synthesis and characterization is reported of an efficient polysiloxane derivative containing the 1,3-bis(9-carbazolyl)benzene (mCP) moiety as a pendant unit on the polysiloxane backbone. In comparison with mCP, the mCP-polysiloxane hybrid (PmCPSi) has significantly improved thermal and morphological stabilities with a high decomposition temperature (Td = 523 °C) and glass transition temper...

Self-assembling systems of colloidal spheres are widely used as templates for the structured deposition of metals and semiconductors. Multilayer samples of ordered polystyrene spheres are prepared by a flow induced process. The subsequent surface activation by a dielectric barrier discharge in oxygen is followed by the fabrication of protecting polysiloxane layers. Electrochemical deposition of...

Liquid/liquid separation after monophasic reactions is a viable way to use and recover polysiloxane-supported catalysts.
