“…While high absorbed doses of ionizing radiation results in cellulose degradation by chain scission, abaca fibers have unique integrity such that its properties remain unchanged even after irradiation up to 100 kGy. 87 This is a characteristic which cannot be observed from most other natural fibers. Moreover, grafting is typically done at low absorbed doses which do not cause significant fiber deterioration.…”

Fiber-reinforced polymer composites have received increased attention due to their environmental friendliness and sustainability, aside from at par-if not betterproperty enhancement achieved through fiber reinforcement over mineral-based fillers. The purpose of this article is to provide a comprehensive review on the various methods of fiber-based polymer composites preparation as well as their applications, particularly focusing on abaca-reinforced hybrid materials. Among the natural fibers available in the market, abaca fiber has been a major contender in the development of natural fiber composites. It has a great potential to be a renewable fiber source for industrial and technological applications owing to its inherent high mechanical strength, durability, flexibility and long fiber length. Impacts of different treatment strategies of abaca-based composites preparation resulting in property enhancements over bare polymer counterparts and that of synthetic fibers are discussed. Being eco-friendly and naturally sustainable, abaca fiber-reinforced composites can also exhibit better strength without substantial weight gaincharacteristics that have been exploited in various commercial and technological uses. How these enhanced properties of the resulting composites had led in a wide range of applications such as in the automobile and construction industries and other fields had been included as well.

“…Among the solid-supported adsorbents, graft-type adsorbents having a thin fiber structure have the considerable advantage because of their large surface area fabrics for the recovery of metals, compared with above polymeric adsorbents. Usually, graft-type adsorbents are prepared by the radiation-induced graft polymerization of vinyl monomers into non-woven fabrics and subsequent immobilization of the ligand to adsorb the metal ions. − Glycidyl methacrylate (GMA) is a suitable monomer for the preparation of a graft-type adsorbent because it contains a vinyl group and an epoxy group that can participate in graft polymerization and ring opening reactions with functional groups. There are many examples of graft-type adsorbents, which are prepared through graft polymerization and subsequent ring-opening of epoxy groups for the immobilization of a ligand such as ethylenediamine, N -methyl- d -glucamine, 2-(aminomethyl)pyridine, triethylenetetramine, and iminodiacetic acid .…”

Poly(vinyl diglycolic acid ester)-grafted polyethylene fabric (PE-PDGA) containing 1.71−4.58 mmol/g millimolar equivalents (meqs) of immobilized tridentate ligand were prepared through radiation-induced graft polymerization of vinyl acetate, saponification, and a ring-opening reaction of diglycolic anhydride. PE-PDGA can adsorb rare earth metal ions, such as Sm, Nd, and Dy, at pH 2.5, with an increase in the removal ratio of the Sm, Nd, and Dy ions observed with an increase in the pH from 2.5 to 4. Furthermore, PE-PDGA more selectively adsorbs rare earth metals, such as Sm, Nd, and Dy, than other metals, such as Cu, Zn, and Co, in the pH range of 2.5−4; 73 mg Sm was adsorbed on 1 g PE-PDGA at an initial metal concentration of 100 ppm at pH 3, while Co was not adsorbed on PE-PDGA in the initial metal concentration range of 10 to 100 ppm. Thus, PE-PDGA showed high selectivity toward rare earth metals, and Sm and Co could be separated effectively.

“…Considering this, an economical and environmentally friendly emulsion grafting method induced by electron beam radiation with water as the solvent should be attempted to prepare low-cost IEMs [29]. Moreover, unlike traditional organic solvents, water as the solvent is less sensitive to attack from free radicals, limiting the chain transfer to the solvent [30], and radiation-induced grafting of monomers in an emulsion state requires a low monomer concentration to achieve a grafting yield (GY) [31,32]. In this study, we successfully prepared a series of AIEMs by the preirradiation-induced emulsion graft copolymerization method.…”

A series of poly(vinylidene difluoride)-based amphoteric ion exchange membranes (AIEMs) were prepared by preirradiation-induced graft copolymerization of styrene and dimethylaminoethyl methacrylate in an aqueous emulsion media followed by solution casting, sulfonation, and protonation. The effects of absorbed dose and comonomer concentration on grafting yield (GY) were investigated. The highest GY of 44.5% at a low comonomer concentration of 0.9 M could be achieved. FTIR, TGA, and X-ray photoelectron spectroscopy (XPS) confirmed the successful grafting and sulfonation of the as-prepared AIEMs. Properties of the AIEMs such as water uptake, ion exchange capacity (IEC), ionic conductivity, and crossover behavior of VO2+ ions prepared by this novel technique were systematically investigated and compared with those of the commercial Nafion 115 membrane. It was found that at a GY of 28.4%, the AIEMs showed higher IEC and conductivity, lower permeability of VO2+ ions, and a longer time to maintain open circuit voltage than Nafion 115, which was attributed to their high GY and elaborate amphoteric structure. Consequently, this work has paved the way for the development of green and low-cost AIEMs with good performance for vanadium redox flow battery applications.
