“…The first requirement could be satisfied by regulating RH to accelerate the solidified rate of PPSU/PU jets, thus forming the 3D fluffy structure. To meet the last two criteria, the mechanically robust PAI nanofibers with high LOI were introduced into the PPSU/PU microfibrous sponges to improve the structural stability and fire retardancy. , …”

Warmth retention equipment for personal cold protection is highly demanded in freezing weather; however, most present warmth retention materials suffer from high thermal conductivity, weak mechanical properties, and strong flammability, resulting in serious security risks. Herein, we report a facile strategy to fabricate nano-/microfibrous sponges with superelasticity, robust flame retardation, and effective warmth retention performance via direct electrospinning. The three-dimensional fluffy sponges with low volume density and high porosity are constructed by accurately regulating the relative humidity; meanwhile, the mechanically robust polyamide-imide nanofibers with high limit oxygen index (LOI) are innovatively introduced to improve the structural stability and flammability of the nano-/microfibrous sponges. Strikingly, the developed nano-/microfibrous sponges exhibit ultralight characteristics (6.9 mg cm–3), superelasticity (∼0% plastic deformation after 100 compression tests), effective flame retardant with LOI of 26.2%, and good heat preservation ability (thermal conductivity of 24.6 mW m–1 K–1). This work may shed light on designing superelastic and flame-retardant warmth retention materials for various applications.

Conductive composites based on thermosetting resins have broad applications in various fields. In this paper, a new self‐compositing strategy is developed for improving the conductivity of graphene nanoplatelet/thermosetting resin composites by optimizing the transport channels. To implement this strategy, conventional graphene nanoplatelet/thermosetting resin is crushed into micron‐sized composite powders, which are mixed with graphene nanoplatelets to form novel complex fillers to prepare the self‐composited materials with thermosetting resins. A highly conductive compact graphene layer is formed on the surface of the crushed composite powders, while the addition of the micron‐sized powder induces the orientation of graphene nanoplatelets in the resin matrix. Therefore, a highly conductive network is constructed inside the self‐composited material, significantly enhancing the electrical conductivity. The composite materials based on epoxy resin, cyanate resin, and unsaturated polyester are prepared with this method, reflecting that the method is universal for preparing composites based on thermosetting resins. The highest electrical conductivity of the self‐composited material based on unsaturated polyester is as high as 25.9 S m−1. This self‐compositing strategy is simple, efficient, and compatible with large‐scale industrial production, thus it is a promising and general way to enhance the conductivity of thermosetting resin matrix composites.
