Four Semi-Interpenetrating Networks (semi-IPN) based on polydimethylsiloxane (PDMS) were developed for the sorptive extraction of polar phenolic compounds (log Kow ≤ 3). Their preparation is based on the hydrosilylation crosslinking reaction of dihydrosilane terminated polydimethylsiloxane with its homologue divinyl, followed by the addition of inert various polyethylene oxide derivatives (PEO). The physico-chemical properties of the semi-IPN were controlled by Differential Scanning Calorimetry (DSC), Scanning Electronic Microscopy (SEM), RAMAN spectroscopy and contact angle measurements, showing the homogeneity of the semi-IPN and their higher hydrophilicity. Under optimum extraction conditions of phenolic molecules as target analytes and using liquid chromatography as analysis techniques, the novel modified PDMS phases showed good extraction rate against polar analytes with an excellent relative recovery average (69-100%) for phenolic molecules. The higher retention rates were obtained with 30% interpenetrated copolymer PEO/PPO in PDMS. Moreover, five adsorption/desorption cycles led to a loss of 5.8 % of the adsorption efficiency, showing a good stability of these PDMS-based IPN phases.

“…Viscoelastic polymers as damping materials have attracted considerate interest in recent years because of their high damping values around the glass transition temperature. [86,87] However, the useful damping temperature range of a homopolymer usually only covers a temperature range of 20-30 degrees for acoustical frequencies ranging from 20 to 20 000 Hz, which is rather narrow for practical applications. In fact, the tan d values of good damping materials are generally higher than 0.3 for a temperature range of at least 60 degrees.…”

Veggie-based products: Vegetable-oil-based polymeric materials, prepared by free radical, cationic, and olefin metathesis polymerizations, range from soft rubbers to ductile or rigid plastics, and to high-performance biocomposites and nanocomposites. They display a wide range of thermophysical and mechanical properties and may find promising applications as alternatives to petroleum-based polymers.Vegetable oils are considered to be among the most promising renewable raw materials for polymers, because of their ready availability, inherent biodegradability, and their many versatile applications. Research on and development of vegetable oil based polymeric materials, including thermosetting resins, biocomposites, and nanocomposites, have attracted increasing attention in recent years. This Minireview focuses on the latest developments in the preparation, properties, and applications of vegetable oil based polymeric materials obtained by free radical, cationic, and olefin metathesis polymerizations. The novel vegetable oil based polymeric materials obtained range from soft rubbery materials to ductile or rigid plastics and to high-performance biocomposites and nanocomposites. These vegetable oil based polymeric materials display a wide range of thermophysical and mechanical properties and should find useful applications as alternatives to their petroleum-based counterparts.

“…U V/AMBIENT OR UV/THERMAL dual-curing technology has attracted a significant amount of attention due to the combination of the functionalities of UV and ambient or thermal curing in a curable oligomer-based system. In addition, the modification of epoxy resins with polysiloxanes has been investigated in many researches because polysiloxanes have peculiar characteristics such as chemical stability, low surface tension, water impermeability, weathering resistance, and low dielectric constant [1][2][3][4][5]. However, in order to conform to operating requirements, polysiloxanes are generally needed to be cross-linkable.…”

UV/ambient or UV/thermal dual-curable materials have received great attention due to their increasing applications in protective metal, plastic, glass and optical fiber coatings, and electronic packing materials. In this study, a UV/ambient dual-curable polysiloxane, epoxy/methacryloxy side-groups polysiloxane was synthesized and characterized by FTIR and 1H NMR. The synthesized polysiloxane was mixed with an epoxy methacrylate resin and an amine-curing agent, and then cured to obtain complete insoluble films directly under irradiation at room temperature. The obtained composite cured films with high gloss show a high visible light transmittance, close to 110% and 80%. They also possess excellent thermal, flexibility, hardness, and surface properties.
