TL;DR: Superhydrophobicity is the tendency of a surface to repel water drops as discussed by the authors, and it is defined as the ability of the surface to resist water drops in nature.
Abstract: Superhydrophobicity is the tendency of a surface to repel water drops. A surface is qualified as a superhydrophobic surface only if the surface possesses a high apparent contact angle (>150°), low contact angle hysteresis (<10°), low sliding angle (<5°) and high stability of Cassie model state. Efforts have been made to mimic the superhydrophobicity found in nature (for example, lotus leaf), so that artificial superhydrophobic surfaces could be prepared for a variety of applications. Due to their versatile use in many applications, such as water-resistant surfaces, antifogging surfaces, anti-icing surfaces, anticorrosion surfaces etc., many methods have been developed to fabricate them. In this article, the fundamental principles of superhydrophobicity, some of the recent works in the preparation of superhydrophobic surfaces, their potential applications, and the challenges confronted in their new applications are reviewed and discussed.

TL;DR: In this paper, the abaca-jute hybrid composite has better properties than the traditional abaca composite alone in tensile and shear properties, however, the composite is superior to the hybrid composite in flexural and impact strength, and the internal structure of the composite was observed under scanning electron microscope (SEM) and the fractures, voids and fibre delamination were analyzed.
