This study investigates the development of an organic hybrid composite based on polyvinylidene fluoride and multiwalled carbon nanotubes. We examine use nanoimprinting to form submicron arrays with roughened surface topography composite. nanoscale roughening effect arises from nanotubes at surface, which is absent in imprinted pure fluoride. demonstrate that depositing a thin silver layer onto nanoimprinted containing (MWCNTs) produces approximately 10-fold enhancement surface-enhanced Raman scattering (SERS) signal intensity compared PVDF film also yields significantly higher SERS response than observed flat (nonimprinted) MWCNT/PVDF Furthermore, subjecting superband gap irradiation results additional 2-fold increase strength. research highlights potential polymer doped plasmon active for sensitive efficient chemical detection.

Auxetic structures, characterised by a negative Poisson's ratio, exhibit the unique property of expanding in all directions under tensile loading and contracting when compressed. The behaviour these structures is highly influenced arrangement material within unit cell interactions between cells. Due to complexity their behaviour, understanding modelling auxetic materials pose significant challenges, requiring extensive experimentation sophisticated frameworks. As result, machine learning (ML) techniques have emerged as powerful tool for predicting mechanical properties studying metamaterials various conditions. This review provides comprehensive analysis use ML algorithms performance metamaterials. It discusses details datasets, employed, 3D printing technologies used sample fabrication, geometries explored literature. In addition 3D-printed this also includes findings from finite element-based models. Finally, paper outlines future research directions, highlighting opportunities advance application using techniques.
