“…3,4 However, the normally used diglycidyl ether of bisphenol A (DGEBA) suffers from inherent demerits such as low thermal resistance performances for advanced materials. 7 Thus, exploration of novel epoxy materials with special features, which may surmount the above weaknesses, is extremely desirable. These resins, however, are also limited by their low toughness, poor impact resistance and brittleness, which obviously restrain their applications in some advanced fields.…”

A novel silicon-containing hyperbranched epoxy (SHBEp) has been explored via a one-pot A 2 + B 3 polycondensation reaction using (3-glycidyloxypropyl)trimethoxysilane (A-187) and excess neopentyl glycol (NPG) under solvent-free and catalyst-free conditions. We investigate for the first time bismaleimide (BMI) toughening effect using the fabricated polymer, and a series of SHBEp/BMI thermosets are then constructed, and then their mechanical properties like impact strength, flexural strength, and thermal stability are studied; meanwhile the toughening effect of SHBEp and conventional epoxy resin E51 is also compared. The results indicate that a proper addition of SHBEp (8 wt%) can significantly improve the toughness and thermal performance of thermosets compared to E51 with the same content. It is, therefore, revealed that the polymer is promising to act as an effective BMI toughener. Unexpectedly, a bright blue photoluminescence is observed when the SHBEp is excited under 365 nm UV light, and its average fluorescence lifetime and absolute fluorescence quantum yield are 4.30 ns and 4.61% respectively. It is demonstrated by our primary investigation that the epoxide and hydroxyl groups simultaneously help the light emission. Thus, the SHBEp bearing unconventional chromophores is also particularly expected to be a new light-emitting material. † Electronic supplementary information (ESI) available: GPC curve, the predicted 29 Si NMR of the obtained polymer, TGA and DSC curves, and additional hyperbranched polysiloxanes.

“…More energy was required to propagate a crack in the two discrete networks that interpenetrated or entangled closely with each other, leading to higher crack tolerance under tensile loading. This phenomenon was also observed in other IPN systems [23][24][25]. It is worth noting that the introduction of FETI-19 into polycyanurate simultaneously improved the tensile strength, modulus, and toughness, which is highly desired for the fabrication of high performance composites.…”

Abstract. Highly soluble fluorinated ethynyl-terminated imide (FETI) oligomers were prepared via a conventional one-step method in m-cresol, using 4, 4′-(hexafluoroisopropylidene) diphthalic anhydride and 2, 2′-bis(trifluoromethyl) benzidine as the monomers, and ethynylphthalic anhydride as the end-capper; then interpenetrating polymer networks (IPN) were formulated from FETI oligomers and bisphenol A dicyanate ester (BADCy) through a solvent-free procedure, and their thermal, mechanical, and dielectric properties were fully characterized. The curing mechanism was studied by model reactions using nitrogen nuclear magnetic resonance. As evidenced by differential scanning calorimetry analysis and rheological measurements, the FETI/BADCy blends exhibited lower curing temperature and shorter gelation time in comparison with pure BADCy due to the catalytic effects of ethynyl and residue amic acid groups. The properties of IPNs were fully compared with those of polycyanurate, and the results revealed that the incorporation of FETI into cyanate ester resins could significantly improve the toughness, glass transition temperatures, mechanical and dielectric properties of the resultant IPNs.

“…The latter system yields thermosets with high Tg (> 250 °C), reduced moisture absorption and liquid processability. More recently, BMI/epoxy blends have been suggested as a suitable matrix for fabricating rigid risers for oil and gas rigs via filament winding [96]. While promising, there are still issues that need to be addressed for this application, such as the potential galvanic corrosion of these carbon fibre based composites in deep sea environments, an issue not addressed at all in the publication despite the known weakness of BMIs in this area [97].…”

Full terms of use are available: http://www.bristol.ac.uk/pure/about/ebr-terms Hamerton, E-mail: ian.hamerton@bristol.ac.uk This review is respectfully and affectionately dedicated to Dr Horst D Stenzenberger, who has been an inspirational figure in modern BMI chemistry, always happy to share his extensive knowledge of this field. ABSTRACT:The chemistry of bismaleimides (BMIs), their blends and copolymers is reviewed critically with particular emphasis placed on the development of the field after 1990, which was marked by several comprehensive review articles. A general introduction to the structure property relationships of BMIs is presented, outlining the development of the preparative chemistry, and the early strategies adopted to address the inherent brittleness of the cured 'first generation' BMI polymers. 'Second generation', diallylbisphenol-toughened BMIs, form the basis of the benchmark commercial systems, and the polymerization mechanism is discussed. The current review is placed in context, addressing the issues of cost, processing and precursor toxicity, the major barriers to wider acceptance of BMIs. The main body of the review evaluates a number of observations made by Dr Horst Stenzenberger in 1990, for the future development of BMI technology. Hence, the synthesis of novel bismaleimide building blocks, incorporation of new thermoplastics and additives, and blending with new thermosetting comonomers are all discussed in detail. The aforementioned review had been written before the concept of nanocomposites or shape memory polymers had been explored with BMIs, but the fields have since grown (especially in the case of the former topic) and are reviewed herein. The application of BMIs to continuous fibre composites is one of the proposed fields of commercial development. The topic falls a little beyond the scope of the present review of BMI chemistry, and is the subject of another publication, but a brief discussion of the most recent developments is presented. The review is concluded with some thoughts about the future outlook for BMI chemistry.
