“…According to TGA data, two consecutive mass losses were observed. They can be attributed to the elimination of PEG segments and chlorinated PP segments, respectively [23]. TGA curve of PPEG 400-1 and PPEG 2000-1 were almost identical.…”

Since the dissolution of polyolefins is a chronic problem, melt processing has been tacitly accepted as an obligation. In this work, polypropylene (PP) was modified on molecular level incorporating poly(ethylene glycol) (PEG) as graft segment (PP-g-PEG) in a range of 6 to 9 mol%. Gold nanoparticles were nucleated in the presence of the copolymer chains via redox reaction. The dissolution of the amphiphilic comb-type graft copolymers containing gold nanoparticles (80 nm in diameter) was achieved in toluene and successfully electrospun from its solution. The diameter of composite fibers was in the range from 0.3 to 2.5 µm. The design of the structurally organized copolymer fiber mats provided a support medium for the nanoparticles enhancing the active surface area for the catalytic applications. The resulting composite fibers exhibited rapid catalytic reduction of methylene blue (MB) dye in the presence of sodium borohydride (NaBH 4 ) compared to corresponding composite cast film.

“…The difference observed in the graft copolymers could be explained by the interaction of the polymer surface chains with the water. The apparently lower hydrophilicity of PP-g-PEG more likely resulted from a lower WCA value of PEG-alkyne [18,72]. Overall, this simple route enabled to tailor the wettability of commercially available PP-Cl by inclusion of different type of polymers as pendant groups.…”

“…For example, antibacterial [12], antifouling [13] and hydrogen storage [14] properties of polypropylene were enhanced via surface-initiated atom transfer radical polymerization [15]. Chlorine atoms on the polymer chains both develop polarity and allow reactive sites for a series of monomer such as acrylates, methacrylates and styrenes [16][17][18][19]. Polymers containing chlorine atoms, such as chlorinated poly (vinyl chloride) (CPVC), poly(vinyl chloride) (PVC), chlorinated polyethylene and polypropylene exhibit high fire and cold resistance as well as plasticity.…”

Abstract. Graft copolymers from commercial chlorinated polypropylene (PP-Cl) possessing either poly(ethylene glycol) (PEG) or poly(ɛ-caprolactone) (PCL) grafts are synthesized by copper (I)-catalyzed azide-alkyne cycloaddition 'click' reaction (CuAAC). For this purpose, azido-functional polypropylene is prepared by nucleophilic substitution of chlorine groups of PP-Cl with azidotrimethylsilane-tetrabutylammonium fluoride. Whereas, the clickable alkyne end-functional PEG and PCL are independently synthesized by esterification reaction of poly(ethylene glycol) methyl ether with 4-pentyonic acid at room temperature and ring-opening polymerization of ε-caprolactone using stannous octoate as catalyst and propargyl alcohol as initiator. Finally, the corresponding graft copolymers, PP-g-PEG and PP-g-PCL, with different surface properties were successfully synthesized by CuAAC 'click' reaction under mild condition. Spectral, chromatographic and thermal analyses at various stages prove the formation of desired polypropylene-based graft copolymers with well-defined properties. Furthermore, the water contact angle values of PP-Cl, PP-g-PEG and PP-g-PCL are found as 90±1°, 78±1.8° and 83±2.1°, respectively.

“…For example, cellulose diacetate semipermeable membrane embodying noble metal nanoparticles (Au and Pt) has been prepared [12]. Polypropylene (PP) is a polymer which has good mechanical properties and has many medical applications, such as tissue replacement and organ wall reconstructions [13][14][15][16][17]. However, to obtain a wider medical application, nanoparticles can be embedded [17].…”

Silver metal nanoparticles were immobilized in chitosan/carboxymethylcellulose/BMI.BF 4 (1-n-butyl-3-methylimidazolium tetrafluoroborate ionic liquid) (CS/CMC/IL) to form polymeric membrane with 20 m thickness. The CS/CMC/IL polymeric membrane was prepared using a simple solution blending method. Irregularly shaped Ag(0) nanoparticles with monomodal size distributions of 8.0 ± 0.4 nm Ag(0) were immobilized in the membrane. The presence of small Ag(0) nanoparticles induced an augmentation in the CS/CMC/IL film surface areas. The CS/CMC/IL membrane containing Ag(0) showed increase antimicrobial activity the Ag(0) concentration increased up to saturation at 10 mg. CS/CMC/IL membrane that contains Ag(0) nanoparticles has enhanced durability of the membrane and exhibited stronger antimicrobial activity against Escherichia coli and Staphylococcus aureus.
