Synthesis of vinyl ester resin-carrying PVDF green nanofibers for self-healing applications

Heat Resistant Vinyl Ester Resins for Composite Applications

Unsaturated polyester and epoxy vinyl ester resins have broad utility in composite applications. Today’s commercially available premium thermal performance vinyl ester resins are derived from novolac epoxies and methacrylic acid. These products combine low viscosity with shelf stable, yet fast curing properties, and enable fabricators to manufacture composite parts with rapid throughput for dem...

Sliding Wear Behaviour of Walnut Shell Powder Filled Vinyl Ester/ WSP Green Composites

Polyvinyl ester green composites were synthesized with walnut shell powder (WSP) by in-situ polymerization technique. The green composites have been evaluated for mechanical properties such as tensile strength, tensile modulus and hardness. Sliding wear loss, specific wear rate and coefficient of friction were investigated by using computerized pin-on–disc machine at normal applied loads of 20,...

Successful Initial Development of Styrene Substitutes and Suppressants for Vinyl Ester Resin Formulations

Development of Chitosan/Poly(Vinyl Alcohol) Electrospun Nanofibers for Infection Related Wound Healing

Chitosan is a cheap resource, which is widely used in biomedical applications due to its biocompatible and antibacterial properties. In this study, composite nanofibrous membranes of chitosan (CS) and poly(vinyl alcohol) (PVA) loaded with antibiotics at different ratios were successfully fabricated by electrospinning. The composite nanofibers were subjected to further analysis by scanning elect...

Synthesis of Zataria Multiflora extraction loaded chitosan/PEO nanofibers via electrospinning method for potential biomedical applications

Background & Objective: The nanofibers are referred to as fibers with a diameter of less than 1000 nm. There are various ways to make nanofibers, one of which is electrospinning. In this method, nanofibers are formed on aluminum sheets. The conversion of chitosan to derivatives with greater solubility, its mixing with other polymers and the use of special solvents are methods for its ease of us...
