“…In the present work, chitosan (partially deacetylated derivative of chitin) is associated with Arabic gum (through a reaction mediated by epichlorohydrin) for preparing a support that is functionalized with two reagents bearing sulfonic moieties: 2-acrylamido-2-methyl propane sulfonic acid (AMPS) and 2-[(p-aminophenyl)sulfonyl]ethyl hydrogen sulfate (ASES). In addition to the specific ion-exchange properties of sulfonic groups (strong cationic exchanger), their presence increases the hydrophilic behavior of the sorbent [42]. Alexandratos and co-workers reported the criteria that can control the reactivity of sorbents [43][44][45].…”

A composite of sulfonated waste polystyrene (SWPS) and graphene oxide was synthetized by an inverse coprecipitation in-situ compound technology. Polystyrene (PS) has a wide range of applications due to its high mechanical property. the graphene were incorporated into sulfonated polystyrene (SPS) to improve the thermal stability and mechanical performance of the composites. Functionalized graphene were synthesized with tour method by using recovered anode (graphite) of dry batteries while sulfonated waste expanded polystyrene was obtained through sulfonation of the polymer. The SPS and GO + SPS composite were characterized using by Fourier Transform Infrared spectroscopy (FT-IR) and transmission electron microscopy (TEM). While the degree of sulfonation (DS) was determined through elemental analysis. The results show the degree of sulfonation of the composite is 23.5% and its ion exchange capacity is 1.2 meq g−1. TEM analysis revealed that the GO particles were loaded on the surface of sulphonated polystyrene and that the SWPS was intercalated into the sub-layers of nanoG homogeneously, which result in an increase in electrical conduction.

“…Figure 3 and 4 show the appearance of the Batch A and B SPMMA at the sulfonation times of 2, 4 and 6 hrs. The sulfonation reaction involved aromatic electrophilic substitution [9]. The addition of the sulfonate groups on the PMMA would allow the PMMA to have the ability to bind with the cations respectively [8].…”

Cranioplasty is the surgical procedure to repair the bone defects in the cranium. Poly(methylmethacrylate) (PMMA) is the most common used biomaterial as it showed better long-term outcomes. Cranioplasty is usually performed through in-situ forming approach. However, the heat and shrinkage and the release of unreacted monomers represent the main drawbacks. Studies also shown a rate of graft infection higher than 10% in surgical PMMA cranioplasty. To overcome these, prefabricating the implants using additive manufacturing (AM) has been proposed. The AM implants could be tailored according to the defect and reduce surgical time, blood loss and the risk of infection. However, the insufficient disinfection of the AM implants may increase the risk of infection. Therefore, the implants can be loaded with antimicrobial agents prior to the cranioplasty. This study synthesised a chemically modified PMMA that can be loaded with antimicrobial agent for AM. The PMMA was sulfonated under different sulfonation temperature, duration, and ratio of PMMA to sulfuric acid. The ionic exchange capacity and degree of sulfonation of the sulfonated PMMA (SPMMA) was determined. In the future, SPMMA with the optimal IEC and DS will be loaded with antimicrobial agent and will be evaluated using the zone of inhibition assay.
