“…All-solid-state lithium ion batteries are attracting increasing interest for a new generation of energy storage devices. Solid-state lithium ionic conduction materials play a significant role in the functioning of all-solid-state lithium ion batteries. − Currently, solid-state lithium ionic conduction materials such as inorganic ceramic materials and polymer-based materials are being intensively studied . However, the inorganic ceramic materials have poor contact with the electrode interface and the polymer-based materials have low ionic conductivity at RT, both of which limit the development and application of solid-state lithium ion batteries.…”

Metal−organic frameworks (MOFs), due to their possessing a porous structure, are potential candidates for solid-state ionic conduction materials. Moreover, uncoordinated carboxylic acid groups (−COOH) of MOFs can be used as postsynthetic modification sites, which are favorable for lithium ion exchange. Herein, we synthesized a unique multiple carboxylic zinc metal−organic framework (Zn-MOF-COOH) containing uncoordinated carboxylic acid groups. Zn-MOF-COOLi was synthesized through deprotonation using LiOH via a straightforward acid−base reaction at room temperature (RT), thereby exhibiting better good electrochemical properties. The lithium ionic conductivity (σ) increased from 1.81 × 10 −5 to 1.65 × 10 −4 S• cm −1 , lithium ion transference number (t Li + ) rose from 0.67 to 0.77, and the electrochemical window improved from 2.0−5.5 to 1.5−6.5 V. This work offers a new strategy to improve the σ of MOFs and a new perspective toward manufacturing of high-performance solid-state ionic conduction materials.

“…Postprocessing techniques such as irradiation and mechanical treatment would also influence such properties. However, polymers like PVA require higher order of effort to see any appreciable modifications in their properties using such methods [13][14][15]. Due to which they have been given very less importance in making sensor films for radiation.…”

“…They may be sensitive for very high magnitude of impact but very poor in sensing/recording smaller magnitudes of impact (magnitude refers to dose in kilo-Gray in case of irradiation, load in mega pascal in the case of pressure, etc.) [13][14][15]. One such important field is sensing of UV radiation exposure duration for few seconds.…”

This paper presents the preparation and characterisation studies of UV sensing films with a simple mathematical model for quantifying the lower UV irradiation duration/doses. To observe any appreciable changes in any properties of Poly-vinyl alcohol (PVA) films with UV irradiation, it has to be treated for few hours/days together. However, the technique presented here is an ultrasensitive method in which, the quantum dots (QDs) reinforced PVA film has become sensitive to UV radiations even for few seconds of exposure. To achieve this, Mercaptopropionic acid (MPA) capped CdTe QDs with superior fluorescence spectral properties grown in water medium were dispersed in PVA matrix to prepare QD-Polymer nanocomposites. Such fluorescence enriched films were stored in room temperature in ordinary environmental conditions for four years to check the degradability and viability. The stability of fluorescence and electrical properties of QDs inside PVA matrix was remarkable in this test period and were retained by the films even after such long duration. After that they were treated with UV radiation with the interval of few seconds to check the exposure recording ability of such films. The results are very promising in terms of sensitivity and the recording ability. Using the least square linear fit method a mathematical model was developed which would be useful in UV exposure sensing for smaller duration. This study also helps the concerned industries who would prepare film sensors for UV exposure quantification (like Litmus paper for pH sensing).

“…With different kinds of additives or dopants further these properties can be improved or fine-tuned [2][3][4][5]. Also, there are fair number of irradiation techniques applied to modify the properties of PVA films [6][7][8][9]. The work presented here is another method used to process PVA in view of physical and electrical properties changes.…”

The shock wave impact effects have been studied on PVA (Poly Vinyl Alcohol), thin films in view of morphological and electrical property changes. The PVA films of thickness around 0.25 mm are subjected to shock waves impact of Mach number around 1.7 to 1.8. The samples are subjected to 0, 25, 50, 100 and 150 numbers of shocks, in a time interval of around 15 s between the shocks. The shock waves are generated with an in-house developed shock tube capable of producing shock waves of Mach number up to 2. The films are further characterized with FTIR, UV-visible spectral analysis for chemical and physical changes and the EDAX, SEM image analysis further confirmed the effects. The trend in the I-V characteristics and the impedance data obtained clearly shows the significant increase in the conductivity of PVA films. Thus, shock wave impact method proves to be another method of treatment of materials and the results obtained promises about the possible electrical applications of PVA films.
