Influence of filler material on properties of fiber-reinforced polymer composites: A review

The current day target for material scientists and researchers is developing a wholesome material to satisfy the parameters such as durability, manufacturability, low cost, and lightweight. Extensive research studies are ongoing on the possible application of polymer matrix composites in engineering and technology, since these materials have an edge over conventional materials in terms of performance. Hybridization of reinforcements is considered to be a better option to enhance the efficiency and performance of composite materials. Accordingly, research studies focus on the surface treatment of natural fibers and the addition of nanofillers (natural or synthetic) by industry and academia to take the properties and application of composites to the next level. This review purely focuses on the influence of fillers on the properties of composites along with the probable application of filler-based polymer composites.

Application of Nano-Biomaterials Scaffold in Postoperative Nursing Care of Orthopedic Fractures

This article detects the drug-carrying capacity of the new chitosan/silk fibroin/nano-hydroxyapatite multilayer composite scaffold and analyzes its efficacy in postoperative care of orthopedic fractures. The article uses animal experiments for comparative analysis. All animals undergo fracture model establishment. One group uses nano three-dimensional scaffold materials loaded with antibiotics, one group is pure nano three-dimensional scaffold materials, and the last group is without any implantation treatment. Finally, it was found that the fracture recovery of the three groups of animals was different. In particular, all the antibiotic-loaded nano three-dimensional scaffold material group indicators are better than the other two groups. For this reason, we conclude that the new chitosan/silk fibroin/nano-hydroxyapatite multilayer composite scaffold has a strong drug-carrying capacity. The stent is worthy of clinical promotion and use in orthopedics.

Chitosan/Silk Fibroin Materials for Biomedical Applications-A Review

This review provides a report on recent advances in the field of chitosan (CTS) and silk fibroin (SF) biopolymer blends as new biomaterials. Chitosan and silk fibroin are widely used to obtain biomaterials. However, the materials based on the blends of these two biopolymers have not been summarized in a review paper yet. As these materials can attract both academic and industrial attention, we propose this review paper to showcase the latest achievements in this area. In this review, the latest literature regarding the preparation and properties of chitosan and silk fibroin and their blends has been reviewed.
