“…Band gap was calculated using Tauc's relation same as that of used in our previous report of PVC/NC polymer blends. 41 From band gap spectra, it was observed that energy gap of polymer blends decreased as a function of NC blending. Band gap was decreased from 4.96 eV for pure PAN to 4.62 eV for PAN/NC polymer blends.…”

Polyacrylonitrile (PAN) polymer blends were more in demand due to their wide range of applications. We overcome the restricted low thermal stability and poor strength for deployable blend. In the present study, we prepared PAN and nitrocellulose (NC) polymer blends by solution casting method to overcome the low loss, low dielectric properties as alternative blend for cladding purpose in communication domain. C≡N bond exclusively demonstrated the impact on blending was confirmed by Fourier‐transform infrared spectrophotometer (FTIR) and Raman microscopy measurement. Semicrystalline nature of polymer blends as a function of NC loading was determined by X‐ray diffraction (XRD). Optical polarizing microscopy (OPM) and scanning electron microscopy (SEM) analysis illustrated an appearance of micro flocculated spherulites. Blending ratio of PAN/NC demonstrated the decreased direct band gap identified by Ultraviolet spectroscopy (UV). PAN/NC proved excellent alternative as low dielectric constant and low loss as cladding medium. Blending of NC with PAN exhibited an increased hydrophilicity was confirmed by surface goniometer. Increased thermal stability of polymer blends was mapped by thermogravimetric analysis (TGA). Blend melting temperature and glass transition temperature was increased from 322°C to 334°C and 88°C to 102°C confirmed by Differential scanning calorimetry (DSC) analysis. Thermal conductivity was increased from ~0.13 to ~0.34 W/m. k for PAN/NC determined by Lee's disc probe method. Mechanical properties of blends were measured using universal testing machine (UTM). Tensile strength and Young's modulus was increased up to ~23%, and ~ 56%, whereas elongation break was decreased up to ~71% for PAN/NC blends compared to host PAN system. PAN/NC may suit promising candidate as cladding blend for communication engineering due to low loss and low dielectric constant.

In the present work, we have prepared polymer blend of polyvinyl butyral (PVB) and poly (3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT: PSS) by solution casting route. Blends were tested for various structural, morphological, and electrochemical techniques. Structural properties were investigated by XRD technique exploring the contribution conducting polymer in host system PVB exhibit amorphous nature. COO functional group contributed in blend configuration was confirmed by FTIR technique. Clustering of PEDOT:PSS in blend system were observed by scanning electron microscopy.Subatomic surface topology and increased roughness due to blending concentration of conducting polymer were analyzed by probe microscopy techniques.Increased softness of blends was confirmed by shore "A" durometer test. PVB/PEDOT:PSS blend was drop casted on glassy carbon electrode and employed for detection of various metal ions. It was deployed for electrochemical sensing of Cu 2+ ion. Electrochemical sensing investigation was done by differential pulse voltammetry technique. Performance of blends at 4.5 pH, 200 s deposition time and À1.2 V deposition potential was more accurate and sensitive toward detection of Cu 2+ ion. The developed electrochemical sensor exhibited rapid sensing response in the range of 1.6 to 8.3 μM. Furthermor,e an influence of many analytical parameters such as pH, deposition time and deposition potential on Cu 2+ ion investigation were disclosed. This investigation may be feasible to construct a very simple, fast, and efficient electrochemical sensing system for toxic heavy metals at low-level concentration.

The accumulation of non‐biodegradable plastic waste in land and aquatic environments is expanding every day. According to data collected from various scientific reports, about 100–250 megatonnes of plastic waste arrives in the oceans annually. According to the Central Control Board of India (2019–2020), India produces about 3.5 million metric tonnes of plastic waste annually, while only 5–10% of the produced waste is recycled. The non‐recycled plastic waste dumped into the environment either goes to landfills or directly goes to the sea, which disrupts the marine life of the ocean. We are highly dependent on plastic at household and industrial scales. Removal of plastic waste and lowering the use of hazardous and non‐biodegradable plastics are the main challenges. Researchers and industrialists have come up with many ideas to lower the generation of non‐biodegradable plastic waste and found that reusability is easier than degradability, while the use of bioplastics is the ultimate solution to tackle the plastic waste problem. Hence, developing eco‐friendly alternative plastics without compromising physicochemical and mechanical properties is the need of the hour. An eco‐friendly alternative to conventional or petrochemical plastics is bioplastics, which are environmentally safe, and reduce our dependency on fossil reserves. Therefore, this review focuses on eco‐friendly bioplastics as an efficient alternative to non‐biodegradable plastics. Among renewable and sustainable feedstocks available, vegetable oils are the most suitable resource for bioplastic production because of their renewability and economical nature. Hence, this study concluded that polyurethane‐based polymers from vegetable oils are inherently more eco‐friendly than most other plastics. © 2023 Society of Industrial Chemistry.
