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...

Abstract A novel convenient synthesis process for 1,3-bis(chlorodiorganosilyl)-cyclodisilazanes is developed via an intermolecular dehydrochlorination of 1,3-dichloro-tetraorgano-disilazane, in the presence of a strong organic alkaline deacidification agent 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU). This procedure involves a one-step process under mild synthesis condition, with higher production efficiency and product purity as compared to those of the previously reported methods. The formation o...

Abstract To generate a novel heat-resistant phenolic epoxy resin, carborane containing curing agent (1,7-bis(aminophenylene)meta-carborane) was synthesized and applied to cure the resin. The generated carborane-containing phenolic epoxy resin showed better thermal stability and thermal oxidative stability than carborane free phenolic epoxy resin. And the Lap Shear Strength of bonding samples showed the improved bonding performances. The thermal degradation mechanism of carborane-epoxy resin was ...

Abstract Poly(carborane-siloxane) polymers were successfully synthesized by tris(pentafluorophenyl)borane catalyzing diorganohydroxysilanes (Si OH) and dihydrosilanes (Si H) to form siloxane bond and release hydrogen. The structure of monomers and polymers were characterized by 1H, 13C, 29Si NMR and FI-IR. Furthermore, in the present study, the qualitative characterization of silicon hydrogen bond in dihydrosilanes activated by catalyst B(C6F5)3 was investigated by 1H NMR relaxation test and the...

Abstract Polymorphic transformation from the form II to form I crystal was investigated for isotactic polybutene-1 (PB) and butene-1/ethylene copolymers (PBE) with differential scanning calorimetry (DSC) and dielectric response spectroscopy (DRS). DRS detected the so-called α relaxation of segments within the amorphous phase, and DSC traced a degree of form II to I transformation with time. It turned out that incorporation of the ethylene comonomers in PBE suppressed the crystallization and plas...

The ionic conductivity and the mechanical strength are two key factors for the performance of poly(ethylene oxide) (PEO) based polyelectrolytes. However, crystallized PEO suppresses ion conductivity at low temperature and melted PEO has low mechanical strength at high temperature. Here, random binary brush copolymer composed of PEO- and polystyrene (PS)-based side chains is synthesized. PEO crystallinity is suppressed by the introduction of PS brushes. Doping with lithium trifluoromethanesulfona...

Abstract This paper reports a high-yielding, efficient and facile method in preparing monomers, namely 1,7-bis(hydroxyl(dimethyl)silylmethyl)- m -carborane ( M1 ), 1,7-bis(diethylamino(dimethyl)silylmethyl)- m- carborane ( M2 ), 1,3-dimethyl-1,3-diphenyl-siloxanediol ( M3 ) and diethylaminomethylphenylsilane ( M4 ). The reaction of M2 and M3 to get polymer P1, and the reaction of M1 and M4 to get polymer P2 which has a promising lead in searching for materials with high-temperature properties. T...

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...
