“…The HIPE process was rarely used with polysiloxanes as starting material [14][15][16][17][18][19][20]. After the first synthesis of macroporous silica monoliths in 1998 with a combination of an o/w emulsion and a sol-gel processing by Imhof and Pine [20], further developments were made by Backov et al [15][16][17][18][19].…”

“…Recently, ordered mesoporous non-oxide materials [6], silicon carbide fibers [7] and ceramic foams [8] could be obtained by the so-called polymer precursor route of PCS and metal-substituted PCS derivatives after pyrolysis [9]. There are various synthetic routes for controlling the PCS structure, which is unambiguously important for pursued ceramic materials with sufficient ceramic yields.…”

Abstract:In the present study, the synthesis of poly(1,1-dimethylsilacyclobutane) (PDMSB) by anionic ring opening polymerization (ROP) is reinvestigated, leading to narrowly distributed molar masses (polydispersities 1.04-1.15) in the range of 2.3 to 60 kg mol −1. Investigations of thermal behavior for low molar mass PDMSB revealed an untypical multiple peaks melting phenomenon, which at first glance, seems to be of the same origin as low molar mass poly(ethylene oxide)s. Small angle X-ray scattering (SAXS) and X-ray diffraction (XRD) measurements are done, proving the fast crystallization and subsequent recrystallization for investigated low molar mass samples. Synthetic attempts are expanded to the surface-initiated anionic ROP of 1,1-dimethylsilacyclobutane (DMSB) monomer from the surface of cross-linked polystyrene (PS) nanoparticles. Novel polycarbosilanes (PCS)/organic core/shell particles are obtained, which are investigated by using transmission electron microscopy (TEM) and dynamic light scattering (DLS) experiments. First insights into the crystallization behavior OPEN ACCESSPolymers 2013, 5 285 of surface-attached PDMSB chains reveal that crystallization seems to be hindered.

“…Ceramic foams have been widely used in a range of fields, such as filters, catalysts supports, bone scaffolds and refractories, due to their characteristics of high permeability, high porosity, high specific surface area, and good thermal stability [1][2][3][4]. In these extensive applications, microstructural features of ceramic foams, such as the morphology, porosity, and pore size, are crucial factors that dominate the functional properties of the final product [5].…”
