“…One of the traditional formulations consists of a wetting agent (resole, also acting as a binder), a binder (novolac), micrometer-sized abrasive particles (e.g., alumina–corundum) and commonly known fillers (e.g., clay, zeolite, and carbon black). Fillers play a very important role in abrasive articles for example, they protect the resin from decomposition [7,8,9]. …”

Functional lignin–SiO2 hybrid fillers were prepared for potential application in binders for phenolic resins, and their chemical structure was characterized. The properties of these fillers and of composites obtained from them with phenolic resin were compared with those of systems with lignin or silica alone. The chemical structure of the materials was investigated by Fourier transform infrared spectroscopy (FT-IR) and carbon-13 nuclear magnetic resonance spectroscopy (13C CP MAS NMR). The thermal stability of the new functional fillers was examined by thermogravimetric analysis–mass spectrometry (TG-MS). Thermo-mechanical properties of the lignin–silica hybrids and resin systems were investigated by dynamic mechanical thermal analysis (DMTA). The DMTA results showed that abrasive composites with lignin–SiO2 fillers have better thermo-mechanical properties than systems with silica alone. Thus, fillers based on lignin might provide new, promising properties for the abrasive industry, combining the good properties of lignin as a plasticizer and of silica as a filler improving mechanical properties.

“…Despite increased stiffness of the composites, as an effect of incorporation of chemically modified zeolite, damping properties which are strongly connected with final product durability are higher in comparison to materials containing unmodified zeolite. Already in previous studies, it was observed that the cross-linking process depends on the filler type and under certain circumstances can be accelerated by the said fillers [29]. In Table 6, the relative value of DH is presented: with respect to the resin without filler.…”

Mechanically robust and thermally stable abrasive tools from phenolic resins reinforced with diazonium‐modified zeolites

The contact area between the filler and the polymer is a critical region that influences to a great extent the filler–matrix adhesion and therefore the mechanical properties of the composite. Controlling the type of interactions at this interface has a significant effect on the properties of the composite materials. In this context, we prepared composites by covalent reaction of diazonium‐functionalized zeolite with phenol‐formaldehyde resin. Introducing the hydroxymethyl groups onto the surface of the filler via diazonium chemistry allows for covalent bonds between the resin and the modified filler. Such a modification resulted in higher flexural strength of the composites, better ability to dissipate mechanical energy during load and also better damping properties (which are strongly linked to the final product durability) compared with the composites bearing pristine zeolite filler. Moreover, application of modified filler accelerates the crosslinking of novolac resin used as a binder in abrasive tools. One key feature of the work was brought by thermogravimetric analysis–mass spectrometry results which indicate no release of toxic urotropine degradation products for composites containing modified fillers. This work demonstrates conclusively that diazonium‐functionalized zeolite filler particles improve remarkably the thermal and mechanical properties of novolac‐based composites. Such robust composites have high potential in the production of novel abrasive tools. POLYM. COMPOS., 40:3209–3219, 2019. © 2018 Society of Plastics Engineers

Over the past 60 years, gas chromatography ( GC ) has been developed into the most powerful separation technique for volatile compounds. This chapter describes milestones in this success story, classic and recent developments in modern instrumentation of GC , current applications and trends as well as future perspectives, and how they fit together. Sections discuss novel stationary phases, comprehensive GC , GC detectors, the referencing of GC data as well as instrumental miniaturization, applications in the analysis of fatty acids, flavor compounds, pollutants and drugs as well as special sections on direct enantiomer separations using modified cyclodextrins, inverse gas chromatography, and microgas chromatographic separations.
