Toughening of vinyl ester resins by two-dimensional MXene nanosheets

Two-dimensional nanosheets are highly effective tougheners for vinyl ester resins. The toughening effect is related to the high specific surface area and unique two-dimensional planar structure of the nanosheets. In this study, a coupling agent γ-(2,3-epoxypropoxy) propytrimethoxysilane (Kh-560) was used to modify MXene nanosheets (M-MXene) for use in toughening vinyl ester resin. The mechanical properties, including the tensile strength, flexural strength, Young’s modulus and elongation, of neat vinyl ester resin and vinyl ester resin modified with MXene and M-MXene were investigated. The results showed that modification significantly improved the mechanical properties of the vinyl ester resin. The tensile and flexural strengths of the MXene-nanosheet-modified vinyl ester resin were 27.20% and 25.32% higher, respectively, than those of the neat vinyl ester resin. The coupling agent improved the interfacial compatibility between the MXene nanosheets and vinyl ester resin, which resulted in the tensile and flexural strengths of the M-MXene-nanosheet-modified vinyl ester resin being 52.57% and 54.60% higher, respectively, than those of the neat vinyl ester resin for a loading quantity of nanosheets of only 0.04 wt %, which is economically viable. The main mechanisms by which the nanosheets toughen the resin are crack deflection and crack pinning.

环氧乙烯基酯树脂指的是分子二端含有乙烯基酯基团、中间骨架为环氧树脂的一类不饱和聚酯树脂。它们由不饱和有机一元羧酸和环氧树脂进行开环酯化反应得到。MFE-10乙烯基酯树脂为低苯乙烯含量环氧乙烯基酯树脂，对降低挥发性有机化合物的污染、改善工作环境都具有非常重要的意义。MFE-10特别适合于拉挤、缠绕等热固化玻璃钢成型工艺。FRP光缆加强芯是以玻璃纤维和环氧乙烯基酯树脂为主要原料，通过拉挤工艺而制成的。可取代钢丝成为新型的光缆加强芯。     

乙醇在聚氨酯/乙烯基酯树脂互穿网络中的吸收动力学及传递分析

采用石英弹簧称重法测定了乙醇在几种聚氨酯（PU）／乙烯基酯树脂互穿网络（IPN）中的吸收动力学数据，用蠕变传递模型对实验数据进行关联，并对IPN的微观结构进行了分析。结果表明：乙醇在PU／含促羟基的乙烯基酯树脂（CBIPN）膜和PU／正丁醇接枝乙烯基酯树脂（HBIPN）膜中的D远大于在PU膜和PU／不含仲羟基的乙烯基酯树脂（PIPN）膜中的D，关联得到的CBIPN和HBIPN膜的杨氏模糊也远大于纯PU和PIPN膜，与其它实验结果相吻合，说明在网络间引入化学键或氢键作用能有效地改善聚氨酯／乙烯基酯树脂互穿网络的相容性，从而提高材料的力学性能     

Electrically conductive thermosetting resins containing low concentrations of carbon black

A cured vinyl ester resin containing electrically conductive carbon black (CB) particles shows electrical percolation at very low CB concentration (<0.5 phr). CB particles have a strong tendency to agglomerate in a low‐viscosity resin, such as vinyl ester, unsaturated polyester resin, and epoxy resins. The agglomeration process in the low‐viscosity vinyl ester resin generates electrically conductive paths already in the resin's liquid state, which undergo partial fixation by room temperature curing and full fixation by hot postcuring. The fully cured castings containing CB concentrations above percolation are characterized by a constant, temperature‐independent conductivity, over a wide temperature range. The current–voltage relationships of the cured vinyl ester/CB castings obey a power‐law dependency. The presence of the continuous CB paths in the vinyl ester casting is clearly observed in fracture surfaces formed at 100°C. © 2000 John Wiley & Sons, Inc. J Appl Polym Sci 76: 1165–1170, 2000

Processing and mechanical properties of bio‐derived vinyl ester resin‐based composites

A “green” vinyl ester resin (GVER) is investigated for use in structural applications. The GVER was formulated using a monodisperse vinyl ester created via a novel synthetic route capable of using bio‐waste material from paper and biodiesel industries. The GVER was used either as a neat resin or as blended with a commercial vinyl ester resin. The processing viscosity and gel times are investigated. The GVER reaches a similar viscosity as the commercial resin with only half the styrene monomer content, thereby reducing the volatile organic compounds associated with manufacturing. Composites of the GVER matrix reinforced by carbon fabric were tested for their tensile and flexural properties. The mechanical performance of the GVER compares favorably with commercial resin and provide a route for composites manufacturing from sustainably sourced vinyl ester matrix. © 2016 Wiley Periodicals, Inc.
