“…PBS can be naturally degraded into the environment by bacteria and fungi [27,28]. Furthermore, PBS has excellent biodegradability in nature, such as in soil, lake, sea, and compost [29]. It can be completely combustible by fire without evolving toxic gases as described in [30].…”

The poly(butylene succinate) (PBS) biodegradable composites reinforced with jute fibers were developed. The effect of fiber content (10-60wt%) on the properties and water absorption of jute/PBS biodegradable composites was studied. The effect of alkali, silane, and combined alkali and silane surface treatment on the properties and water absorption of jute/PBS composites was investigated. The mechanical properties of surface treated jute/ PBS composites were significantly higher than those of untreated ones. Compared with alkali or silane treatment, the combined alkali and silane surface treatment showed better mechanical properties of jute/PBS composites. The best mechanical properties of jute/PBS composites were achieved at 50wt% in this study, which showed an increase in tensile strength by 517.9%, tensile modulus by 3529.8%, flexural strength by 302.6%, and flexural modulus by 1949.1% compared with those of PBS resin. Fractured surface morphologies of composite specimens exhibited an improvement of interfacial fiber-matrix adhesion in the composites reinforced with surface-treated jute fibers. The surface-treated jute/PBS composites having good fiber-matrix adhesion resulted in stable composites with better thermal stability than untreated jute/PBS composites. The water absorption amount of the composites increased with increasing the fiber content. The surface-treated jute/PBS composites showed relatively lower water absorption behavior compared to untreated ones.

“…18 In conclusion, some previous attempts to analyze the biodegradation of aliphatic polyesters affected by O 2 , N 2 , He, and NH 3 plasma treatments were reported. [13][14][15][16][17] However, the results of these studies were scattered and no clear conclusions were obtained in the case of the biodegradation properties. So, in this research, we decided to investigate the influence of O 2 and CF 4 plasma treatments on the surface and in vitro degradation properties of PLLA polymer films, to compare and to analyze the effects of two completely different surface wettability on the degradation properties of the PLLA films.…”

The aim of this research was to investigate the effects of plasma treatment on the surface and on the in vitro degradation behavior of poly(L‐lactide) (PLLA) films. Polymer films were prepared by solvent casting, and their surface was modified by radiofrequency plasma treatments by using oxygen and tetrafluorocarbon gas. Pristine and treated PLLA films were characterized by field emission and atomic force microscopy and by contact angle measurements. In vitro hydrolytic degradation studies were conducted by measurements of weight loss, water absorption, visual inspection, and thermal transitions as a function of the incubation time. As‐deposited PLLA films show a uniform distribution of ring‐like porous structures on the surface due to solvent evaporation. Plasma treatments produce a mass reduction following the etching of the polymer surface. Moreover, the morphology of the porous polymer is modified by the plasma, which induces different micro/nanometric topographic reliefs as a function of the different selected plasma processing parameters. The results indicate PLLA surface become hydrophilic and the surface roughness increased with treatment time in the case of oxygen, whereas a hydrophobic behavior was induced with tetrafluorocarbon plasma treatment. However, in vitro degradation studies show that plasma treatments do not affect the PLLA bulk and the hydrolytic degradation properties. © 2012 Wiley Periodicals, Inc. J Appl Polym Sci, 2012
