“…The results indicate that the partially hydrolyzed EVA was successfully prepared, and some of the acetate groups were successfully changed into hydroxyl groups. The peak related to hydroxyl groups in E5 spectrum is broad, which is probably attributed to the hydrogen bonding (Tambe et al, 2008). Moreover, the weak peak of acetate groups can be still observed in Fig.…”

“…Hydrolysis of EVA was carried out as reported by Hirata et al (2005) and Tambe et al (2008). In a 250 mL three-necked round bottom flask with a reflux condenser, 25 g EVA was added and dissolved in 125 mL tetrahydrofuran, then 40 mL alcoholic NaOH solution (0.5 mol/L) was added at 30 • C. After a predetermined reaction time (i.e., 1, 3 and 5 h), the reaction medium was neutralized by 7.5 mL HCl solution (1 mol/L).…”

“…The hydrolysis degree was determined as reported by Tambe et al (2008). In a 150 mL round bottom flask with a reflux condenser at 80 • C, 1.0 g hydrolyzed product or EVA (blank test) was dissolved in 25 mL toluene, then 5 mL mixture of acetic anhydride and pyridine (7:3 (v/v)) was added and the reaction was continued for 24 h. After that, 5 mL distill water was added and the reaction was stopped after 10 min.…”

“…An important reason for this is that the process has only been successfully used for neat thermoplastics [5][6][7][8][9][10][11][12] e.g. polyamide, polyethylene, PMMA, vinyl chloride copolymers or thermoplastic composites [13][14][15].…”

Thermal spraying is a green solvent-free process with the potential of applying polymer coatings to large components in-house or on-site without the need for prolonged drying. Almost no systematic research has been undertaken on thermally spraying thermoset coatings owing to the complexity and difficulty of managing the curing process. An adequately cured thermoset coating could not be deposited by thermal spraying owing to insufficient cumulative time above the cure temperature. Preheating and post-heating the substrate under a constant heat source were not successful as they led to non-uniform curing, residual stress and the risk of overheating. This study develops and validates a computer model that simulates the deposition of thermoset coatings on metal substrates using thermal spraying and high-energy infrared irradiation. The model uses readily-available commercial software and enables precise control of the coating process to improve energy efficiency and coating quality. Further research showed that evenly cured coatings could be achieved by using variable heat fluxes and controlled utilization of inward conduction from the outer surface layers. Self curing during cooling was significant and may be employed to increase energy efficiency. The thickness of the metal substrate was shown to be an important variable as it acts as a heat sink and, for heavy sections, can substantially increase energy consumption. The results indicate a need for sufficiently accurate process control and provide a suitable methodology for the deposition of thermoset coatings.

Flexible lithium‐ion batteries (LIBs) with high energy density are of urgent need for the ever‐increasing flexible and wearable electronic equipments, but limited by the low areal loading of active materials in traditional electrodes with lamellar structure. It is still a great challenge to solve the sluggish electron/ion transport problem caused by increasing the areal loading of active materials. Herein, a kind of ethylene vinyl acetate copolymer (EVA) is proposed to provide flexible supports and ion channels for ultra‐thick flexible LFP/CNT/EVA cathode and LTO/CNT/EVA anode, thereby achieving high energy density and all flexible LIBs. LFP/CNT/EVA shows a ternary homogeneous structure formed by the entanglement of EVA chains and CNT on LFP, which attributes to LFP content up to 80wt% and adjustable thickness from 20 to 460 µm. In sharp contrast to previous studies LFP/CNT/EVA delivers basically the constant specific capacity of ≈160 mAh g−1 at a 0.1 C rate with the thickness increasing, thus achieving ultrahigh areal capacity up to 4.56 mAh cm−2. A flexible full LIBs based on LFP/CNT/EVA and LTO/CNT/EVA is demonstrated and exhibits favorable cycle performance under an alternant flat and bending state. Those findings are supposed to open new avenues for designing high‐energy‐density flexible LIBs for future wearable energy storage devices.
