Abstract Silicone rubber (SR) plays an irreplaceable role in biomedicine and aerospace applications due to its biocompatibility, flexibility and excellent stability in extreme harsh conditions. However, only a few studies focus on SR based shape memory materials, and the increasing intelligent applications of SR materials are limited by the insufficient strength and poor designable recovery behavior. Herein, we report a simple method via monomers/prepolymers blend and in situ polymerization/cros...

The introduction of fillers/additives into polymer matrices is a practical and effective method for preparation of damping materials. In the current work, a designed 9,10-dihydro-9-oxa-10-phosphaphenanthrene 10-oxide-based oligosiloxane (DOPO-PMVS) was used as an additive to improve the damping properties of methyl phenyl vinyl silicone rubber (PVMQ). The preparation of high damping PVMQ elastomers with broad temperature range has been discussed, and the effect of silica, DOPO-PMVS, vinyl conten...

In this paper, a series of polysiloxanes, presenting different contents of densely simple and well-defined short-branched chains (G1–G5), are prepared by hydrosilylation of α,ω-(dimethylvinylsiloxy)-poly(dimethyl-methylvinyl)siloxanes (P1–P5) with 1,1,1,3,5,5,5-heptamethyltrisiloxane (MDHM) and characterized by 1H and 29Si nuclear magnetic resonance, Fourier transform-infrared spectroscopy, Abbe refractometry, gel permeation chromatography, and differential scanning calorimetry. The rheological ...

For the first time, we report the damping effect of a novel 9, 10-dihydro-9-oxa-10-phosphaphenanthrene 10-oxide (DOPO)-based oligosiloxane abbreviated as DOPO-PMVS on methyl vinyl silicone rubber (VMQ) elastomers. Designed DOPO-PMVS was synthesized by means of hydrophosphination reaction and studied by FT-IR, 1H NMR, 29Si NMR, 31P NMR, and thermogravimetric analysis. The effect of added DOPO-PMVS on damping, mechanical, and thermal properties of VMQ elastomers before and after post-cure was then...

A series of random copolysiloxanes (PCDMS) containing various amount of γ-cyanopropyl groups are prepared by a new method under mild conditions. Structures of the synthesized polymers are fully characterized by FTIR, 1H NMR, 29Si NMR, and GPC. Rheological properties of PCDMS are tested by cone and plate rheometer, and thermal properties by differential scanning calorimetry (DSC) and thermogravimetry analysis (TGA). Damping properties as well as fuel resistance of the cured PCDMS elastomers are a...

Abstract New polysiloxane derivatives ( P1 and P2 ) having mixed phenyl-substituted cyclodisilazane in the main-chain were synthesized. Their thermal properties have been characterized by differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). The glass transition temperature ( T g ) of P1 and P2 would be dependent on the polymer structure and were in the range of −27∼−80 °C. The T g s decreased considerably with an increase in the content of the siloxane main-chain groups ...

The title mol­ecule, C60H70N2O4Si8, lies on an inversion center. In the asymmetric unit, one of the phenyl rings is disordered over two sets of sites with refined occupancies 0.58 (2) and 0.42 (2). In addition, in two substitution sites of the terminal dimeth­yl(vin­yl)silyl unit, a methyl group and the vinyl group are disordered over the same site with refined occupancies 0.523 (13) and 0.477 (13).

A new type of polymeric curing agent (PCA) was synthesized to improve processing property, increase mechanical properties, and decrease volume shrinkage of silicone rubber. The PCA was prepared by co-hydrolysis condensation of dimethyldiethoxysilane (DDS) and polyethoxysiloxane, then modified by hexamethylcyclotrisilazane (D3N). Commercial silica and tetraethoxysilane (TEOS) were used as controls simultaneously. The properties of polydimethylsiloxane (PDMS) composites were characterized by shear...
