“…One effective approach to improve the thermal performance of polybenzoxazine is to introduce crosslinkable units into the structure of the benzoxazine, such as ethynyl groups, nitrile groups, propargyl groups and allyl groups to stabilize the Mannich Bridge during thermal degradation. Another effective method is to introduce the inorganic component into the organic polybenzoxazine . For example, Ardhyananta et al reported the preparation of Polybenzoxazine(6,6′‐(1‐methylethylidene)‐bis‐(3,4‐dihydro‐3‐phenyl‐2H‐1,3‐benzoxazine,Ba)/polydimethylsiloxane(PDMS) hybrids by sol‐gel method.…”

A serial of addition-curable hybrid resins for resin matrix of advanced composites are prepared by thermal prepolymerization between acetylene-functional benzoxazine(BZ) and polyvinylsilazane(PSN) with various weight ratios. Processing capability of BZ-PSN resin is investigated by measuring viscosity. Cure behavior is investigated by differential scanning calorimetry (DSC) and Fourier transform infrared (FT-IR) spectra. Thermal property of cured BZ-PSN resin is investigated by Thermogravimetric analysis (TGA) and Dynamic mechanical analysis (DMA). BZ-PSN resin shows a low viscosity of 40-180 mPaÁs between 60 and 90 C, and maintains the low viscosity for 6 h, indicating that the resin is suitable for resin transfer molding (RTM) process to fabricate composites. DSC results show that BZ-PSN resin can be cured completely at about 250 C without adding any other curing additives. FT-IRshows the reaction between BZ and PSN take place. TGA shows that thermal stability of cured BZ-PSN resin is increased with the content of polyvinylsilazane increasing both in nitrogen and in air. DMA shows cured hybrid resins have excellent thermal properties. The excellent processability and thermal properties suggest that BZ-PSN resin is a promising candidate for resin matrix of advanced composites.

“…In 1994, the synthesis and properties of crosslinked polybenzoxazines and their properties were first reported by Ning and Ishida 14. Since then, numerous articles have been published on monomeric benzoxazines,15–27 main‐chain type polybenzoxazine28–39 and side‐chain type polybenzoxazines 40–45. It is this high molecular weight polybenzoxazine precursors with side‐chain type structures that the current article aims at developing because high‐molecular weight precursors offer usual thermoplastic properties, such as good film forming ability and solubility in solvent for easy structural analysis.…”

A side‐chain type benzoxazine‐functional cellulose has been developed using click chemistry via the reaction of ethynyl‐monofunctional benzoxazine monomer and azide‐functional cellulose. The synthesis, crosslinking, and thermal properties of the benzoxazine‐functional cellulose are studied by NMR, FTIR, DSC, and TGA. The crosslinking reaction of the benzoxazine side‐chain unusually takes place at low‐temperatures in comparison to an ordinary benzoxazine resins. Upon crosslinking, the polymer shows high char yield of 40%, which is a marked improvement from a mere 4% of the unfunctionalized cellulose. © 2012 Wiley Periodicals, Inc. J Appl Polym Sci, 2012

“…An effective approach is the introduction of novel structures in main molecular chain . Other strategies for performance improvement of PDSEPE are the copolymerization with other resins . In this work, an inorganic nano‐material was incorporated in PDSEPE to form composites, aiming to enhance the mechanical properties of PDSEPE, at same time to functionalize the polymer.…”

Polymer composites with carbon-based nano-fillers have generated significant interest in industry and science because of their multifunctional and valuable properties. An APA-functionalized GO nanofiller (GO-APA) was prepared through the reaction between graphene oxide (GO) and 3-aminophenyl acetylene (APA) in dimethylformide (DMF) with ammonia hydroxide. Furthermore the PDSEPE/GO-APA composites were made from Poly(dimethysilyleneethynylenephenylene ethynylene) (PDSEPE) and GO-APA. FT-IR, XRD, XPS, SEM, DSC and TGA techniques were used to characterize the chemical compositions and physical and chemical properties of GO-APA and PDSEPE/GO-APA composites. As a result, the prepared PDSEPE/GO-APA composites show high thermal stabilities, excellent electrical conductivity and good flexural strength. When the weight percentage of GO-APA reaches 0.5%, the PDSEPE/GO-APA composite electrical conductivity increases by 6 orders of magnitude and the flexural strength improves by nearly 33% compared with that of cured PDSEPE resin.
