“…It was observed that the incorporation of silk fiber increased the intensity as well as the crystallinity of the film composite. The higher crystallinity value of the composite film could be attributed to the nucleating effect caused due to the addition of the silk fibers trapped in the macromolecular chains of the blends as a result of the polar interaction of the functional groups of silk with the matrix .…”

“…From the TGA, it can be seen that the PVA/PVP film as well as the film composites show three decomposition steps. For the pure blend, the initial decomposition occurred at 70°C–140°C with a mass loss of 7.4% due to the loss of bound water molecules and acetic acid in the polymer . Maximum degradation occurred between 200°C and 365°C accompanied by a major weight loss of about 42% due to the melting and breakdown of the blend segments.…”

In the present study, short fiber‐reinforced hybrid composite films of poly (vinyl alcohol) (PVA) and poly (vinylpyrrolidone) (PVP) with different weight percentages of silk fiber, were prepared by the solvent casting technique. The thermal, mechanical, morphological, and bio‐degradable characteristics of the prepared films were evaluated. Soil burial experiments were performed in order to study the bio‐degradation rate of the composite films. The composite films showed good mechanical strength with increasing fiber concentration along with good thermal and biodegradable properties. This could possibly be due to the chemical interaction of the fiber functional groups and the matrix, as implied from the results of Fourier transform infrared spectroscopy, thus making them an exceptional material to be safely disposed without causing ecological damage.

“…In particular calcium-based nanoparticles have shown to have therapeutic benefits when used in cutaneous wound repair (Kawai et al, 2011). On the other hand, sericin has high antioxidant potential (Prasong, 2011;Kumar and Mandal, 2017), antibacterial activity (Ramesan et al, 2016), mitogenic effect on cells (Terada et al, 2005), potential to inhibit inflammation (Aramwit et al, 2012a), and ability to retain hydration (Padamwar et al, 2005). In the study of Aramwit et al, a sericin-based therapeutic cream formulation improved healing by promoting collagen production and rapid re-epithelialization in rat skin wounds (Aramwit et al, 2009(Aramwit et al, , 2013.…”

Recent Advances in Silk Sericin/Calcium Phosphate Biomaterials

et al. 2020

Calcium phosphates (CaPs) have been widely used in the field of biomedical engineering as bone graft substitutes or as carriers for drug delivery applications. Recent developments have focused on combining CaPs with proteins to obtain functional biomaterials that accommodate a broader spectrum of functional requirements. Silk sericin was considered an unutilized protein by-product from the textile industry, generating tons of residues every year. However, much effort has been dedicated to its recovery after being associated with numerous biological properties such as antioxidant, antibacterial, anti-coagulation and regenerative activities. In the past years, sericin has also demonstrated to be suitable as a template for CaP mineralization. The present review focuses on the recent developments for the production of sericin/CaP composites, exploring their potential applications in bioengineering and opening new avenues in other research fields such as in the cosmetic, food and environmental sectors. In addition, this paper can also be useful as a guideline to design future research based on sericin/CaP biomaterials.

In this study, we report the preparation of polymer blend nanocomposites based on chitin (CT)/cashew gum (CG) with various contents of magnetite nanoparticles (Fe3O4). The fabricated nanocomposites were characterised by FT infrared (FTIR), X‐ray diffraction (XRD), high‐resolution transmission electron microscopy (HRTEM), magnetic property (vibrating sample magnetometry (VSM)), differential scanning calorimetry (DSC), thermogravimetry (TGA) and impedance analyser. FTIR study revealed the characteristic absorption and shifts of peaks of the blend matrix, the shifts being attributed to the intermolecular interaction of Fe3O4 nanoparticles with CT/CG segments. The amorphous domain of the blend decreased with an increase in the concentration of nanoparticles was observed from XRD analysis. The HRTEM images showed the uniform arrangement of nanoparticles within the CT/CG network. VSM studies showed the ferromagnetic nature of the blend composite with an increasing saturation of magnetism with super‐paramagnetic behavior. DSC and TGA results revealed that the glass transition temperature and thermal stability of the composites were increased by the addition of magnetite nanoparticles. AC and dielectric properties were much improved in the entire range of frequencies due to the interaction with Fe3O4 nanoparticles. The role of nanoparticles on mechanical properties has been carefully studied. The tensile strength and hardness of magnetite filled nanocomposites become significantly higher in comparison to unfilled compounds and the nanocomposite with 10 wt. % of nanoparticles showed the maximum tensile strength.
