“…This composite possesses the lowest crystallinity (65.1%) as shown in Table 1. This was also observed in the work of [9] where the low crystallinity was attributed to the presence of cold crystallization. The melting peak for PLA/CH (5 wt.%) and neat PLA is the same (159°C); PLA/CHS (10 wt.%) and PLA/CH (2.5 wt.%)/CHS (2.5 wt.%) have their melting peak at 152°C while that of PLA/CHS (5 wt.%), PLA/CH (10 wt.%) and PLA/CHS (wt.%)/CH (5 wt.%) occurred at 165°C, 169°C and 149°C respectively.…”

“…Although electrospinning is a simple and quick method in the fabrication of nano-fibrous scaffolds, there still exist challenges in the fabrication of scaffolds with complex structures, such as the homogeneous distribution of pores, thus limiting its application in biomedicine. In the study, [9] observed that the addition of particles can lead to the formation of a porous fibre network, which enables the material to absorb water and solvents. The introduction of new biopolymers and fabrication techniques that offer advantageous characteristics in wound dressing materials is important [8].…”

Conventional wound material allows bacterial invasions, trauma and discomfort associated with the changing of the dressing material, and the accumulation of body fluid for wounds with high exudate. However, there is a shift from conventional wound dressing materials to polymeric nanofibers due to their high surface area to volume ratio, high porosity, good pore size distribution, which allows for cell adhesion and proliferation. There is an urgent need to synthesis a biodegradable composite that is resistant to bacterial infection. In this study, an electrospun polylactide (PLA) composite suitable for wound dressing, with enhanced antimicrobial and mechanical properties, was produced. The neat PLA, PLA/CH (10 wt.%), PLA/CH (5 wt.%), PLA/CHS (10 wt.%), PLA/CHS (5 wt.%), PLA/CH (2.5 wt.%) /CHS (2.5 wt.%) and PLA/CH (5 wt.%)/CHS (5 wt.%), were electrospun using 0.14 g/ml solution. Results show that crystallinity (67.6%) of neat PLA declined by 3.8% on the addition of 2.5 wt.% chitin/chitosan with improved hydrophilicity of the composite. The tensile strength of neat PLA (0.3 MPa) increased (0.6 MPa) with 2.5 wt.% chitin/chitosan addition. The slight increase in the glass transition temperature from 75°C for neat PLA to 78°C of the composite fibre, showed improved ductility. The fibres showed little beads, hence suitable for wound dressing. The electrospun mats have good water absorption capacity and strong resistance against Staphylococcus aureus. Good performance was attained at 5 wt.% of chitin, chitosan and hybrid reinforcements. Therefore, a PLA/chitin/chitosan composite is recommended as a wound dressing material.

“…The formation of pores www.advancedsciencenews.com www.ms-journal.de or dimples is also due to the combined effect of nature polymer, rate of evaporation of solvent, temperature, etc. [24,25] In the present work, pit or dimple formation is due to the combined effect of moisture, solvent volatility, and non-water-soluble nature of P(VDF-TrFE). P(VDF-TrFE) is a non-water-soluble polymer and methyl ethyl ketone (MEK) is a volatile solvent, the fast evaporation of solvent and water molecule condensation during the elongation of electrospun jet gives dimples or pits on the nanofiber.…”

Electrospun polymeric nanofibrous membranes find application in various fields such as biomedical, energy, defense, etc. The flexibility of the electrospinning process and various parameters like temperature, solvent volatility, and polymer nature helps to design nanofibers with desired properties. The wide range application of nanofibers is because of its large surface to volume ratio. The surface area of a nanofiber can be further increased by fabricating dimpled or porous fibers. In the present work, dimpled electrospun polyvinylidene fluoride-co-trifluoroethylene (P(VDF-TrFE)) nanofibers are prepared. The surface nanotopography of the fiber is studied using SEM and TEM analysis. The influence of rough surface on the wettability is evaluated by contact angle analysis. The result indicates that the nanofibrous membrane exhibits a very high contact angle (140°). In addition to this, mechanical property and thermal behavior of the membrane are also studied. The study reveals that the dimpled electrospun nanofibrous membrane is an excellent candidate in various applications where a large surface area is required.

“…The matrix was melt-blended with each of the fillers at the weight percentages shown in Table 15 . Although there are several polymer composites processing technique [8] , [9] , [10] , [11] , the melt-blending technique was used because it is environmentally benign, cost-effective, best for mass production, toxin-free [12] and allows for the addition of higher weight per cent of fillers. The weight per cent formulation of the fillers was obtained from the mass of the fillers ( Table 15 ) according to Eq.…”

Polylactide (PLA), a biopolymer, was reinforced with three fillers (two organic reinforcements and one inorganic filler). The processing technique used to fabricate the composites was the melt-blending technique. The composites and the unreinforced PLA were subjected to microhardness, compression and biodegradation characterisations. Data obtained are presented in this article as raw data. Data from microhardness and compression tests were used to predict the fracture toughness. The biodegradation of the composites was also examined, and the data obtained reported in this article. The data presented in this article allow for a comprehensive understanding of the mechanical behaviour and the biodegradation profile of three composites of PLA with respect to their applications as biodegradable implants. It also helps in the selection of fillers for biopolymers such as PLA.
