MXenes, two-dimensional (2D) transition-metal carbides and nitrides with high electrical conductivity, show outstanding potential for energy storage applications. However, the aggregation and restacking of 2D MXene nanosheets seriously decrease the performance of MXene-based electrodes. Instead of using high-cost artificial templates, herein, we select natural rubber (NR) latex-containing uniform sub-macroparticles as sacrificial templates and successfully construct three-dimensional interconnected porous MXene foam. This porous structure effectively prevents the restacking of MXene nanosheets and accelerates the transfer of electrolyte ions during charging and discharging, which significantly enhances capacitance and rate performance. By adjusting the loading of latex, we find that MXene foam (MXF)-70% provides both improved specific capacitance of 480 F g −1 at 2 mV s −1 and superior rate performance (42.1% residual at 1 V s −1 ) with excellent cycling stability of 97.1% capacitance retention after 10000 cycles at 50 mV s −1 . Additionally, the low cost of natural rubber latex provides an alternate route to produce foam electrodes on a large scale for portable and integrated supercapacitors.

“…Molecules 2024, 29, 913 2 of 15 pathogenic bacteria also harm the health of patients receiving medical treatment. Although the antibacterial properties of natural rubber can be realized through the use of doping and blending certain fillers [8][9][10], an active surface is difficult to maintain in the long term. The modification of antibacterial active molecules on the surface of a substrate can confer longterm antibacterial activity, but there are few studies on the fixation of antibacterial active molecules on the surface of an NR substrate [11].…”

A simple strategy was adopted for the preparation of an antimicrobial natural rubber/graphene oxide (NR/GO) composite film modified through the use of zwitterionic polymer brushes. An NR/GO composite film with antibacterial properties was prepared using a water-based solution-casting method. The composited GO was dispersed uniformly in the NR matrix and compensated for mechanical loss in the process of modification. Based on the high bromination activity of α–H in the structure of cis-polyisoprene, the composite films were brominated on the surface through the use of N-bromosuccinimide (NBS) under the irradiation of a 40 W tungsten lamp. Polymerization was carried out on the brominated films using sulfobetaine methacrylate (SBMA) as a monomer via surface-initiated atom transfer radical polymerization (SI-ATRP). The NR/GO composite films modified using polymer brushes (PSBMAs) exhibited 99.99% antimicrobial activity for resistance to Escherichia coli and Staphylococcus aureus. A novel polymer modification strategy for NR composite materials was established effectively, and the enhanced antimicrobial properties expand the application prospects in the medical field.

“…Consequently, numerous attempts have been made to resolve this issue, including the natural template approach. Natural templates such as starch, gelatin, natural rubber, and gum Arabic are notable advances in the effort to limit the use of synthetic templates [ [25] , [26] , [27] , [28] , [29] , [30] , [31] , [32] , [33] ]. Gelatin has been discovered to be an effective structure-directing agent when combined with synthetic templates in a dual template strategy.…”
