Organofunctional silanes are hybrid materials of silanes having attracted greater attention since the last decade owing to its versatile properties and wide range of applications. In this review, we have summarized the types of organosilanes (RnSiX4-n), their reactions, and applications. Organosilanes usually have two reactive groups, organofunctional groups and hydrolyzable alkoxy groups, which undergo hydrolysis and condensation. Silanols (Si-OH) and siloxane (Si-O-Si) structures are formed by hydrolysis and condensation reactions, respectively. In general, organosilanes acts as excellent binding agent due to its bridging capacity through (Si-O-Si) bond linkage with metal surfaces. From the extensive literature survey carried out, we understand that the silanes are synthesized without comprehending the reaction kinetics mechanism. In the past few decades, significant advances were witnessed in the development of various organofunctional silanes, which were used in a wide range of research areas based on its bifunctional characteristics.

In this review, we have discussed on the latest development in metal nanoparticle composites based on PVDF via electrospinning process for electronic applications. Human robotics, wireless-data communication, nanogenerators, wearable biocompatible/bio-inspirable sensors, motion detectors, and actuators have become a key component in self-powered IoT devices. Due to the power demand, an urge is in the industry for fabricating portable, flexible, and sustainable green micro and nano devices. PVDF and its copolymers have attracted greater attention because of their excellent piezoelectric, dielectric, magnetic, and good mechanical properties, suitable for lightweight application and due to the biocompatible nature. Piezoelectric property can be enhanced with the addition of different metal nanoparticles and can be used for various application like sensor, actuators, energy harvesters, health monitors, EMI shielding. Interesting results reported by many research groups working in this field is consolidated in this review paper.
