“…As shown in Figure 4b, a sharp exothermic peak for the electrode materials at ∼300°C was related to the cyclization of C≡N in the PAN structure, which consistent with previous reports. [31][32][33][34][35][36] This is in good agreement with the TGA results of pure PAN for the initial weight loss at the same temperature (Figure S7). This also confirmed that the chain structure of PAN has changed from aliphatic linear to 2D structure analogical of the graphene-like structure due to the cyclization reaction (depicted schematically in Figure S8).…”

“…This band also disappears after TIN due to the cyclization reaction of C≡N in the PAN chain, which confirmed that the cyclization reaction also took place inside the electrode materials during the thermolysis process. [31][32][33] The DSC results of the electrode materials were consistent with the FTIR spectra. As shown in Figure 4b, a sharp exothermic peak for the electrode materials at ∼300°C was related to the cyclization of C≡N in the PAN structure, which consistent with previous reports.…”

Silicon (Si)-based anodes for lithium-ion batteries are highly attractive due to their high lithium storage capacity, but their performance is typically plagued by huge volumetric changes during battery cycling. Researchers have traditionally considered the roles of interactive binders and conductive additives as separate entities. Necessary additions of these two components often leads to significantly decreased mass ratio of Si to non-active material, which inevitably limits the anode's absolute capacity. To achieve a better utilization efficiency, a multifunctional composite binder was developed by cross-linking a poly(acrylic acid) (PAA) and carboxymethyl cellulose (CMC) spine with polyacrylonitrile (PAN) through a thermolysis induced nanoarchitecturing (TIN) process. The composite binder strongly interacts with Si, providing a sturdy structure with efficient pathways for both Li-ion and electron transport. The cross-linked carboxyl groups from PAA and CMC offered a robust 3D cross-linked network, anchoring SiO 2 coated Si nanoparticles onto a highly-porous carbon scaffold, creating a stable solid electrolyte interphase. The composite anode not only exhibits a high initial capacity of 3472.6 mAh g −1 with an initial Coulombic efficiency of 89.1%, but also provides excellent cycling stability for 650 cycles at a high current density of 3000 mA g −1 .

Polyacrylic acid (PAA) is an important industrial chemical, which has been extensively applied in various fields, including for several biomedical purposes. In this study, we report the synthesis and modification of this polymer with various phenol imides, such as succinimide, phthalimide and 1,8-naphthalimide. The as-synthesized derivatives were used to prepare polymer metal composites by the reaction with Zn +2 . These composites were characterized by using various techniques, including NMR, FT-IR, TGA, SEM and DSC. The as-prepared PAA-based composites were further evaluated for their anti-microbial properties against various pathogens, which include both Gram-positive and Gram-negative bacteria and different fungal strains. The synthesized composites have displayed considerable biocidal properties, ranging from mild to moderate activities against different strains tested.
