“…Pavia et al (2010) [ 31 ] reported that peak of –CH 3 and –CO functional groups usually have bending vibration of approximately 1375 cm −1 and 1300 cm −1 –1000 cm −1 . These two important peaks prove the copolymerization occurred as they only appeared in poly(AAm- co -EMA) spectra [ 32 ].…”

“…Some degradation of both polymers also was observed in the distilled water and they had difficulty in maintaining original shape after reach the equilibrium state. Overall, water absorption for poly(AAm) membrane was slightly higher than poly(AAm- co -EMA) thus the highest ability to absorb water [ 32 ]. It had been reported that polar substitution groups such as –OH and –NH in a structure of polymer will cause problem in controlling the interaction of molecule with water-based solution.…”

An enzyme-based electrochemical biosensor was investigated for the analysis of Sunset Yellow synthetic food dye. A glassy carbon electrode was coated with a poly(acrylamide-co-ethyl methacrylate) membrane to immobilize laccase using a single-step photopolymerization procedure. Poly(acrylamide-co-ethyl methacrylate) membrane was demonstrated to have acceptable water absorption and suitable for biosensor application. Sunset Yellow biosensor exhibited a linear response range from 0.08 to 10.00 µM with a detection limit of 0.02 µM. This biosensor was successfully used to determine Sunset Yellow in soft drinks with recoveries of 99.0–101.6%. The method was validated using high-performance liquid chromatography, indicating the biosensor can be as a promising alternative method for Sunset Yellow detection.

“…In this study, only a small ratio of EMA monomer was added to alter the hydrophilicity of copolymer. This was due to the increasing mass percentage of EMA monomer, which can lead to hydrophilicity disruption of membrane, making it not suitable to use as membranes in sensors [9]. Silver nanowires (AgNWs) are silver nanostructure with a diameter of nanometer that has electrical, optical, and thermal properties.…”

Malachite green is widely used in the aquaculture, food, and textile industries. However, malachite green is carcinogenic, mutagenic, and teratogenic. Therefore, a chemical sensor was developed to detect malachite green in water samples. Screenprinted carbon electrode was coated with (p(AAm-co-EMA)/Ru(bpy) 3 2+ /AgNWs to investigate its potential as a membrane for chemical sensor. The membrane was synthesized using the photopolymerization technique and characterized by fourier transform infrared (FTIR), 1 H nuclear magnetic resonance ( 1 H NMR), swelling test, field emission scanning electron microscopy/electron dispersive X-ray analysis (FESEM/EDX), thermogravimetric analysis (TGA), and cyclic voltammetry (CV). The peak of -CO in the FTIR spectra indicated that the copolymerization was successful. Furthermore, the NMR spectrum confirmed the FTIR result with the presence of peak at 4.2 ppm. Swelling test showed that p(AAm-co-EMA)/AgNWs had a lower swelling percentage than p(AAm-co-EMA) due to AgNWs filling the pores of the membrane, which can be seen in the cross section of the SEM micrograph. Thermal decomposition temperature of the membrane was around 400 °C. Cyclic voltammogram proved that the p(AAm-co-EMA)/Ru(bpy) 3 2+/ AgNWs film coated on screen-printed carbon electrode which acted as a working electrode was able to detect malachite green by showing anodic peak around 0.25 V and cathodic peak around -1.0 V.

Puncak -CO yang hadir dalam spektrum FTIR menunjukkan kopempolimeran telah berjaya. Spektrum NMR mengesahkan spektrum FTIR dengan kehadiran puncak pada 4.2 ppm. Ujian penyerapan air pula menunjukkan peratus serapan air p(AAm-ko-EMA)/AgNWs lebih rendah berbanding p(AAm-ko-EMA) kerana AgNWs memenuhi liang-liang yang terdapat dalam filem seperti yang ditunjukkan pada mikrograf keratan rentas SEM. Penguraian terma berlaku pada suhu 400 °C.

This overview looks critically at the present prospects and future challenges in development of polyethyl methacrylate (PEMA) and its composites. It is shown herein to be a promising candidate for various applications, including energy storage, textile, electronics, biomedical, packaging, coatings and adhesives, etc. Due to its high ionic conductivity, thermal stability, and low cost of synthesis, PEMA is also used as a solid electrolyte in supercapacitors. This polymer has the ability to transport ions efficiently between the two electrodes of the supercapacitor, thereby leading to improved performance and efficiency. Additionally, PEMA can withstand high temperatures without breaking down, thus making it suitable for a range of applications. Further, it is shown due to its unique properties and versatility, PEMA has significant potential for a range of biomedical applications. This review of existing literature strongly suggests that the use of PEMA as a solid electrolyte in supercapacitors can be of significant potential for advancing energy storage technology. It also warrants further research to optimize its use in many other challenging practical applications.
