This work provides an energy saving strategy for strengthening and toughening fluoroelastomer (linear F2314) by using liquid fluorine rubber (HTLF-700). A series of semi-interpenetrating polymer networks based on the F2314 and the crosslinked HTLF-700 (namely F23-CLF-X semi-IPNs) were firstly prepared at low temperatures and characterized using FTIR, SEM, EDS, TGA, DSC, DMA and tensile testing et al. The as-prepared F23-CLF-30 semi-IPNs film possessed well interpenetrating co-continuous phases and thus exhibited prominent mechanical performance with the higher tensile strength (33.0 MPa), the larger elongation at break (165.0%), the better mechanical stability at high and low temperature shock and the higher high-temperature creep resistance compared with the F2314. Meanwhile, the arc Brazilian test indicates that F23-CLF semi-IPNs could be a promising candidate as a polymer binder for polymer bonded explosive (PBX).

这项工作为使用液态氟橡胶 (HTLF-700) 强化和增韧氟橡胶 (线性 F2314) 提供了一种节能策略。首先在低温下制备了一系列基于 F2314 和交联的 HTLF-700 的半互穿聚合物网络（即 F23-CLF-X semi-IPNs），并使用 FTIR、SEM、EDS、TGA、DSC、DMA 和拉伸试验等。所制备的 F23-CLF-30 半 IPNs 薄膜具有良好的互穿共连续相，因此表现出突出的机械性能，具有更高的拉伸强度（33.0 MPa）、更大的断裂伸长率（165.0%）、更好的机械稳定性与 F2314 相比，在高低温冲击和高温抗蠕变性能方面具有更高的性能。同时，
