Aramid nanofibers and poly (vinyl alcohol) nanocomposites for ideal combination of strength and toughness via hydrogen bonding interactions

Highly Multifunctional Dopamine-Functionalized Reduced Graphene Oxide Supercapacitors

“…The rGO-DOPA/10 wt % BANF/Ca 2+ composites exhibited a better combination of mechanical properties than other ANF-based composites such as ANF/epoxy and ANF/PVA. 44,46 To date, the best combination was achieved using 95 wt % ANF/5 wt % CNTs. 72 However, the rGO-DOPA/BANF/Ca 2+ exhibited the highest reported modulus using the lowest content of ANFs in electrically conductive composites, which is important for maintaining good capacitance.…”

“…39 ANFs have been used in a variety of applications including energy storage. 22,[40][41][42][43][44][45][46][47][48][49][50][51] ANF/PEDOT:poly(styrene sulfonate) electrodes exhibited specific capacitance of 112 F/g, Young's modulus of 5 GPa, and tensile strength of 76 MPa. 48 Last year, branched aramid nanofibers (BANFs) were first reported and were shown to bear further improved mechanical properties over ANFs.…”

Enhanced mechanical, thermal, and UV-shielding properties of poly(vinyl alcohol)/metal–organic framework nanocomposites

“…where DH m is the measured melting enthalpy from DSC, DH 0 is the melting enthalpy of the 100% PVA crystalline (138.6 J g À1 ) 39,40 and u the weight fraction of HKUST-1 in the composites. Thermogravimetric analysis (TGA) was performed with a thermal analyzer, Perkin-Elmer TGA7 (ITK Co., Ltd.), at a heating rate of 10 C min À1 and under nitrogen ow.…”

Deacidification of Papers with Hexamethylenetetramine (HMT) in Alcohols and Supercritical Carbon Dioxide

“…On the one hand, the fiber became smooth and elastic because of the imbibition. On the other hand, due to the increased number of hydrogen bonds, the combination of fiber became reinforced (Guan et al, 2017).…”
