“…Each sample showed a glass transition process in a temperature range of −40 and 0 °C, and the T g of PBS was hardly affected by the partial crosslinking. In a previous study, the T g of PBS increased after crosslinking by ultraviolet irradiation which was ascribed to the reduced molecular movement and its rearrangement 14. The T g reflects mobility of polymer segments in amorphous regions.…”

“…The presence of inorganic filler such as silicon dioxide and carbon black enhanced the gel formation. In a recent study, PBS was also crosslinked using ultraviolet in the presence of a photoinitiator (1‐hydroxycyclohexylphenyl ketone) and a crosslinking agent (triallyl isocyanurate) 14. The effect of photoinitiator concentration, crosslinking agent content, and the irradiation time on the crosslink behavior was investigated.…”

PBS is partially crosslinked by using DCP as an initiator. A low gel fraction (<30 wt%) and low crosslink density of the partially crosslinked PBS are obtained at a DCP content of <0.5 wt%. Consequently, the partially crosslinked PBS retains both its processability and its crystallinity. The overall crystallization rate of the PBS is enhanced by partial crosslinking as evidenced by a considerable increase in crystallization temperature (Tc). Meanwhile, the mechanical properties of PBS are significantly improved by the partial crosslinking. The structure/property relationships of the partially crosslinked PBS are explored.

“…The wettability of the plasma-treated polymer substrates depends on the plasma power, bias voltage, type of gas and gas flow. The amount of oxygen adsorbed by the modified polymer surface during and after the plasma treatment is also dependent on the motility of the macromolecular chains, which also influences both the crosslinking on the surface and the crystallinity of the whole polymer [72]. For example, UHMWPE, a polymer with highly motile macromolecular chains [73], exhibits a greater increase in atomic oxygen content after the plasma treatment than PEN, a polymer whose chains are much more rigid due to the presence of the naphthalene group [74].…”

While polymers are widely utilized materials in the biomedical industry, they are rarely used in an unmodified state. Some kind of a surface treatment is often necessary to achieve properties suitable for specific applications. There are multiple methods of surface treatment, each with their own pros and cons, such as plasma and laser treatment, UV lamp modification, etching, grafting, metallization, ion sputtering and others. An appropriate treatment can change the physico-chemical properties of the surface of a polymer in a way that makes it attractive for a variety of biological compounds, or, on the contrary, makes the polymer exhibit antibacterial or cytotoxic properties, thus making the polymer usable in a variety of biomedical applications. This review examines four popular methods of polymer surface modification: laser treatment, ion implantation, plasma treatment and nanoparticle grafting. Surface treatment-induced changes of the physico-chemical properties, morphology, chemical composition and biocompatibility of a variety of polymer substrates are studied. Relevant biological methods are used to determine the influence of various surface treatments and grafting processes on the biocompatibility of the new surfaces—mammalian cell adhesion and proliferation is studied as well as other potential applications of the surface-treated polymer substrates in the biomedical industry.

“…PCL was blended with various other biodegradable polymers in a number of studies [12][13][14][15][16][17][18][19][20][21][22]. Amongst various biodegradable polymers, PBS was the most interesting aliphatic polyester due to its relatively good melt processability, thermal and chemical resistance, biodegradability, and excellent mechanical properties, closely comparable to those of the widely-used polyethylene (PE) and polypropylene (PP) [4,5,[15][16][17][18][19][20][21][23][24][25][26][27][28][29][30][31][32][33][34][35][36]. Double crystalline PCL/PBS blends are particularly interesting because each component has an influence on the crystallization behaviour of the other component.…”

Abstract. Biodegradable polymers received considerable attention due to their contribution in the reduction of environmental concerns and the realization that global petroleum resources are finite. The development of double crystalline biobased blends such as poly(ε-caprolactone) (PCL) and poly(butylene succinate) (PBS) are particularly interesting because each component has an influence on the crystallization behaviour of the other component, and thus influences the strength and mechanical properties of a polymer blend. The lack of miscibility between PCL and PBS constitutes a bottleneck, and efforts have been made to improve the miscibility through the inclusion of copolymers. Having realized that incorporating conductive nanofillers such as carbon nanotubes (CNTs), (especially when the CNTs are functionalized or used as a masterbatch i.e., polycarbonate/MWCNTs masterbatch), into biopolymer matrices, can enhance the thermal and mechanical properties, as well as electrical and thermal conductivity, a lot of research was aimed at the production of bionanocomposites. This review paper discusses the properties of PCL, PBS, their blends, and their CNTs containing nanocomposites.
