The properties of polymer protective coatings of optical fibers. II. The influence of curing time on adhesion of UV‐curable coatings to fused silica surface

Abstract

SYNOPSIST h e dependence of adhesion of four various UV-curable protective coatings of optical fibers t o the surface of fused silica on the time of UV irradiation was investigated. T h e maxima of adhesion were observed in short periods of time of curing. Comparison of adhesion values t o the hardness, gel content, and contact angles of water measured on the polymer surface revealed that adhesion of epoxyacrylate protective coatings of optical fibers depended on the inner structure of the polymer rather than on its surface properties. This observation was confirmed by IR studies.

Multifunctional biphenyl derivatives as photosensitisers in various types of photopolymerization processes, including IPN formation, 3D printing of photocurable multiwalled carbon nanotubes (MWCNTs) fluorescent composites

“…39 The advantages of photopolymerization are undoubtedly its high speed (down to a few seconds), the possibility to control the polymerization process, 40 the absence of solvents and the use of a small amount of energy for the reaction to occur. The photo-induced polymerization of nanocomposites enables not only the production of polymers in mass, but also the creation of laminates 41 and lms with irregular shapes. 42 According to the above, various types of photocurable polymer nanocomposites are currently being studied, especially nanocomposites containing silica nanoparticles.…”

Synthesis of new copolymers 4,4’-sulfinylbisphenol derivative with N-vinyl-2-pyrrolidone - photopolymerization and thermo-mechanical studies

“…Nowadays, modern composite materials include monomers which are distinguished by their high biocompatibility like polyresins based on cyclic ethers, cyclic acetals and allyl sulfides [14][15][16]. Derivatives of bisphenol A dimethacrylate should rather be used for preparation of UV-curable lacquers or coatings [17][18].…”

Synthesis and characterization of silica nanocomposite in situ photopolymerization

“…As far as the in situ polymerization technique is concerned, there are many methods for manufacturing nanocomposites, such as thermal polymerization,7 high‐energy irradiation polymerization,8 and chemical polymerization 9. The ultraviolet (UV) curable technique as a new technology10–12 has been widely used in chemical reactions to prepare organic materials such as film,13 bulk,14 and other irregular types of film materials 15. There have been few reports on UV curable technique used to prepare nanocomposites, let alone a report on the technique of fabricating nanosilica composites based on an organic matrix such as epoxy acrylate as the continuous phase and inorganic nanoparticles such as silicas as the discontinuous phase.…”
