“…1,15 The poly(methyl methacrylate) (PMMA) is a hightransparency amorphous hydroscopic biocompatible thermoplastic polymer with excellent optical clarity and stability upon positron radiation, which can be converted by irradiation from an insulating to a conducting form. [16][17][18][19] PMMA is commonly used in industrial applications, especially in shatterproof windows, illuminated signs, optical and electronic components, and also in microstructures prepared by ion beams. 20,21 The use of PMMA for capacitive humidity sensor preparation has been reported previously in earlier works.…”

“…The surface of PMMA outside the irradiated areas is structureless and flat and after irradiation exhibits significant changes in surface morphology. One can see destruction and a savage surface structure that can be connected with ion induced heating, melting, and depolymerization of PMMA as a result of local thermal spikes 16.…”

Carbon beam writing was employed as a method for maskless production of microscale capacitors in both insulating graphene oxide (GO) and poly(methyl methacrylate) (PMMA) matrix. The GO and PMMA foils were irradiated using a 5-MeV C 3+ beam with micrometer scale resolution. As follows, the shape of the created microstructures and compositional changes was studied using the scanning electron microscopy/energy-dispersive X-ray spectroscopy method (SEM/EDS). The structural and compositional progression was characterized by Raman spectroscopy, Rutherford backscattering spectroscopy (RBS), and elastic recoil detection analysis (ERDA) spectroscopy. The improvement of the prepared structures' electrical properties was also studied, and it can be concluded that carbon irradiation leads to the removal of oxygen and hydrogen and to growth of the carbon domains, which is connected with the conductivity increase of the irradiated parts and capacitance of the final products in the order of pF.

Herein, it is proposed that poly(methylmethacrylate) (PMMA), a widely‐used thermoplastic in our daily life, can be used as an abundant, stable, and high‐performance anode material for rechargeable lithium‐ion batteries through a novel concept of lithium storage mechanism. The specially‐designed PMMA thin‐film electrode exhibits a high reversible capacity of 343 mA h g−1 at C/25 and maintains a capacity retention of 82.6% of that obtained at C/25 when cycled at 1 C rate. Meanwhile, this pristine PMMA electrode without binder and conductive agents shows a high reversible capacity of 196.8 mA h g−1 after 150 cycles at 0.2 C with a capacity retention of 73.5%. Additionally, PMMA‐based binder is found to enhance both the reversible capacity and rate capability of the graphite electrodes. Hence, this new type of organic electrode material may have a great opportunity to be utilized as the active material or rechargeable binder in flexible or transparent thin‐film batteries and all‐solid batteries. The present work also provides a new way of seeking more proper organic electrode materials which don't contain conjugated structures and atoms with lone pair electrons required in traditional organic electrode materials.

Funding information Higher Education Commission of PakistanIn this study, nickel ions were implanted in brass at 2.0-MeV energy doses ranging from 1.9 × 10 14 , 4.8 × 10 14 , and 1.0 × 10 15 ions cm −2 at room temperature. Formation of micro size particle cluster, crater, void, rust, and flower-like structure were observed in scanning electron microscope (SEM) micrographs. XRD patterns explain the plane (1 1 1) and plane (2 2 0) under abrupt fluctuations, but in plane (2 0 0), systematic changes occur after ion implantation. Modifications in crystallite size, lattice strain, and dislocation density were discussed. In all the implanted specimens, values of hardness were smaller as compared with the unimplanted one.Precise changes occurred in the value of d-spacing that produced alteration in electrical conductivity at the initial ion doses. Therefore, electrical conductivity values were changed from 3.980E 6 (S/m) to 2.966E 7 (S/m). Further increment in the ion dose, electrical conductivity reduced to recover its value. Initial trend of hardness and electrical conductivity was nonlinear, but both tend to recuperate their values in the end. In FT-IR spectra, three new bands were formed at 1261, 1417, and 1455 cm −1 after ion implantation that was due to change in bonding of brass.
