“…The identification was carried out by SEM equipped with an energy-dispersive X-ray spectroscopy (EDS) detector (the respective EDS spectra are presented in the Supplementary Information, Figure S3 ). Experimental studies reported in the literature have shown that even the low amounts of lithium chloride (0.5 wt%) present in the polymer sample exhibit plasticizing properties [ 63 , 64 ]. The presence of lithium chloride is manifested by lowering the melting point and the crystallinity of a polymer.…”

Surface Modification of PHBV Fibrous Scaffold via Lithium Borohydride Reduction

In this study, lithium borohydride (LiBH4) reduction was used to modify the surface chemistry of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) fibers. Although the most common reaction employed in the surface treatment of polyester materials is hydrolysis, it is not suitable for fiber modification of bacterial polyesters, which are highly resistant to this type of reaction. The use of LiBH4 allowed the formation of surface hydroxyl groups under very mild conditions, which was crucial for maintaining the fibers’ integrity. The presence of these groups resulted in a noticeable improvement in the surface hydrophilicity of PHBV, as revealed by contact angle measurements. After the treatment with a LiBH4 solution, the electrospun PHBV fibrous mat had a significantly greater number of viable osteoblast-like cells (SaOS-2 cell line) than the untreated mat. Moreover, the results of the cell proliferation measurements correlated well with the observed cell morphology. The most flattened SaOS-2 cells were found on the surface that supported the best cell attachment. Most importantly, the results of our study indicated that the degree of surface modification could be controlled by changing the degradation time and concentration of the borohydride solution. This was of great importance since it allowed optimization of the surface properties to achieve the highest cell-proliferation capacity.

In the present study, polyamide 12 (PA12) and 2,2′‐(1,4‐phenylene)bis(2‐oxazoline) (PBO) were used to modify polyamide 11 (PA11), and then microcrystalline cellulose (MCC) reinforced PA11 composites was prepared via hot pressing. The results showed that the thermoplastic elastomer PA12 was in favor of the toughness of the composites, 12% PA12 increased the impact strength by 53%. The molecular chains of PA11/PA12 blends were extended by PBO, and then had positive effects on the mechanical properties, as evidenced by the fact that the flexural strength and the impact strength of the composites with 0.3% PBO were increased by 13% and 14%, respectively. In addition, morphology analysis indicated PBO was in favor of the interfacial bonding of the composites. MCC significantly increased the flexural strength and modulus by 68% and 283%, respectively.
