Unsaturated polyester and epoxy vinyl ester resins have broad utility in composite applications. Today’s commercially available premium thermal performance vinyl ester resins are derived from novolac epoxies and methacrylic acid. These products combine low viscosity with shelf stable, yet fast curing properties, and enable fabricators to manufacture composite parts with rapid throughput for dem...

In this work, separation performance of supported carbon membranes produced from Novolac Phenolic resin as the main precursor and carbon nanotubes as nanofiller were investigated for separation of CO2 from N2 and CH4. Supports were produced by carbonization of Novolac Phenolic resin-activated carbon mixture, and selective layer was coated by dip coating of prepa...

After blending the triblock copolymer, poly(ethylene oxide-b-propylene oxide-b-ethylene oxide) (PEO-b-PPO-b-PEO) with novolac-type phenolic resin, Fourier transform infrared spectroscopy revealed that the ether groups of the PEO block were stronger hydrogen bond acceptors for the OH groups of phenolic resin than were the ether groups of the PPO block. Thermal curing with hexamethylenetetramine ...

In this paper, we study the radiation-induced processes occurring during implantation of antimony ions into films positive diazoquinone-novolac (DQN) FP9120 photoresist (PR) on silicon by Fourier-transform infrared (FTIR) spectroscopy frustrated total internal reflection (TIR). Ion (II) is found to lead appearance in TIR spectrum a band at 2331 cm–1 caused O=C=O stretching vibrations. The viola...

Here we demonstrate a novel metal-organic thin-film encapsulation technique for resonant gas microsensors to efficiently filter out airborne particles which can negatively affect device performance. The gravimetric sensors are ZnO-on-silicon extensional mode resonators coated with a gas-sensitive material. Mass change caused by chemical reaction and/or physical adsorption can be detected throug...
