“…These specimens exhibit high transparence and low haze. It has been well known that the transparency depends crucially on the crystal morphologies in crystalline polymers . In this work, however, the crystallinity of PLLA is very low (Table S3, Supporting Information) in both neat PLLA and PVDF/PLLA blend.…”

Poly(L‐lactic acid) (PLLA) with high ductility and transparence is fabricated by a blending tiny amount of polyvinylidene fluoride (PVDF) and reactive comb compatibilizers (RCC). Upon blending, the reaction between terminal carboxyl groups in PLLA and expoxy groups in RCC produces graft copolymer (PLLA‐g‐poly(methyl methacrylate) (PMMA)), which locates at the PVDF/PLLA interface due to the balanced stress on two sides. On the one hand, the PVDF domain size decreases remarkably with the help of compatibilization, accounting for the excellent transparence. On the other hand, the interface is enhanced significantly, resulting in an activated PLLA layer surrounding PVDF domains. The thickness exhibits higher magnitude because of the high molecular weight of grafted PLLA (relative to premade compatibilizers). During uniaxial tension, the activated PLLA layers (in addition to PVDF) can cause effective energy absorption and dissipation in the case of percolation of them, which is the reason for the better ductility. These results provide an efficient strategy to improve the ductility and transparence simultaneously.

“…The fillers with nanoscaled size can severely alter the physical traits of the polymeric matrix, permitting the engineering of healed biomaterials that individual materials cannot achieve. The nanomaterials possess an extensive high surface area, compared to conventional microsized fillers, which can generate a strong interface with polymer matrix, suggesting healed mechanical characteristics, while sustaining biocompatibility that affects protein adsorption, cell attachment, proliferation, migration, and differentiation for new tissue formation [109,114].…”

The engineering of tissues under a three-dimensional (3D) microenvironment is a great challenge and needs a suitable supporting biomaterial-based scaffold that may facilitate cell attachment, spreading, proliferation, migration, and differentiation for proper tissue regeneration or organ reconstruction. Polysaccharides as natural polymers promise great potential in the preparation of a three-dimensional artificial extracellular matrix (ECM) (i.e., hydrogel) via various processing methods and conditions. Natural polymers, especially gums, based upon hydrogel systems, provide similarities largely with the native ECM and excellent biological response. Here, we review the origin and physico-chemical characteristics of potentially used natural gums. In addition, various forms of scaffolds (e.g., nanofibrous, 3D printed-constructs) based on gums and their efficacy in 3D cell culture and various tissue regenerations such as bone, osteoarthritis and cartilage, skin/wound, retinal, neural, and other tissues are discussed. Finally, the advantages and limitations of natural gums are precisely described for future perspectives in tissue engineering and regenerative medicine in the concluding remarks.

“…[4][5][6][7][8][9][10][11] However, the construction of hybrid interfaces would not only affect adhesion, but also offer the possibility to impart new properties, such as enhanced conductivity, improved toughness, and stored active moieties as self-healing agents or bactericidal compounds. [10,12] Recent studies have shown the capability of developing functional materials through the incorporation of thin films on reinforcing agents' surface by using the layer-by-layer (LBL) deposition method. [13][14][15][16] In this work, polypropylene composites with hybrid interface were produced by alternatively depositing two polymers on the glass fiber (GF) surface, poly(diallyldimethylammonium chloride) (PDDA) and poly (sodium 4-styrenesulfonate) (PSS) containing oxidized multiwalled carbon nanotubes (MWCNT-COOH), via the LBL method.…”

Interfaces can have a great influence on the behavior and properties of polymer composites. In this work, the versatile and low‐cost layer‐by‐layer technique was used for depositing layers of poly(diallyldimethylammonium chloride) (PDDA) and poly(sodium 4‐styrenesulfonate) (PSS) containing oxidized multiwalled carbon nanotubes (MWCNT‐COOH) on the surface of woven glass fibers (GFs); and polypropylene composites containing the modified GFs were prepared by compression molding. The effect of this novel hybrid multilayered interface on the mechanical properties and fracture behavior of the GF reinforced polymer (GFRP) composites was systematically investigated. For that, in situ tensile tests of the composites were monitored by using the high‐resolution phase‐contrast tomography. We found that the GFRP composites with multilayered interface (GFRP multilayered) exhibited exceptional increase in ductility and fracture toughness (about 25 and 130%, respectively), when compared to the composites without interfacial modification (GFRP untreated). Whereas the failure characteristics of the GFRP‐untreated composites were typical of fragile systems (mainly, delamination), the GFRP‐multilayered exhibited additional toughening mechanisms such as crazing and fibrillation as result of the enhanced interfacial adhesion. Our results clearly indicate that the multilayered interface of PDDA/PSS/MWCNT‐COOH led to a more efficient load transfer from the matrix to the GFs, culminating with the brittle‐to‐ductile transition in the failure mode.
