There are many studies which use different types of reduction methods that affect the final properties of composite material containing silver nitrate (AgNO 3 ). The use of poly(N-vinylpyrrolidone) (PVP) in the composite also affects the final properties of composite material. However, as seen from the literature, it is difficult to find any studies focusing on polymer composite nanofibers reduced using different reduction methods and studies with different PVP loadings which are compared to each other, although it is very important to determine the most suitable reduction method and PVP loading for final composite properties. Thus, in this work, the effect of different reduction methods on polyacrylonitrile (PAN) composite nanofibers incorporating AgNO 3 and the comparison of different amounts of stabilizer (PVP) are studied in detail to determine the most suitable reduction method and the effect of PVP loading on the structure and the properties of the final product. PAN composite nanofibers having different amounts of PVP are reduced by four different methods namely arc-sol method, hydrazine method, arcweb method, and reflux method and characterized by electrical conductivity, mechanical testing, and thermal and SEM analyses. It has been observed that the hydrazine method provides higher breaking strength, electrical conductivity, enthalpy, smallest diameter, and lower cyclization temperature (T c ) than other reduction methods. Presence of PVP results in an increase of breaking strength and cyclization temperature, a decrease of enthalpy and the electrical conductivity. While highest breaking strength was obtained by hydrazine reduction with highest PVP loading, highest electrical conductivity was obtained by hydrazine reduction without PVP. As a direct result of the incorporation of AgNO 3 with or without PVP, insulator pure PAN (10 -12 S/cm) becomes semi-conductive material (10 -7 S/cm), which can be used as an antistatic material.
We propose a strategy to enhance the photocurable properties of the multi walled carbon nanotube (Mwcnt) / binder films through control of the intermolecular interaction between the nanotube and the binder material. For this aim, photosensitive functionalized carbon nanotube was synthesized and by mixing binder, it was cured under UV-light. Epoxy acrylate resin was used as binder and reactive diluents such as HDDA, DPGDA were added as both crosslinker and viscosity extender.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
