“…Pomelo is the largest and heaviest fruit of the genus citrus. Its thick foam‐like structured peel presumably acts, among other things, as a shock absorbing layer to protect the fruit as it impacts on the ground upon being shed . Pomelo‐peel‐derived carbon materials, such as 3D honeycomb‐like carbon and oxygen‐enriched activated carbon, have been reported as high‐performance electrode materials for supercapacitors.…”

A nitrogen‐doped foam‐like 3D carbon plate is prepared by carbonizing a selected biomass precursor of pomelo peel. The carbon plate is composed of interwoven connected carbon tubes and shows a unique 3D interpenetrating macroporous network with binary‐channel structure. Owing to the proper pore structures, short ion‐diffusion paths, high conductivity, and high structure stability, the carbon plate exhibits excellent electrochemical performance as an electrode for supercapacitors directly. A high specific capacitance of up to 338 F g−1 at 1 A g−1, good rate capability with a capacitance retention of 59 % at 20 A g−1, and high cycling stability with only 4 % capacitance loss after 5000 cycles at 20 A g−1 can be achieved in 6 m KOH electrolyte in a three‐electrode system. Furthermore, a symmetric supercapacitor fabricated by using the carbon plates delivers an energy density of 11.05 Wh kg−1 at a power density of 250 W kg−1, and an outstanding cycling stability with only 2.4 % capacitance decay over 5000 cycles at 5 A g−1 in 6 m KOH electrolyte. These very attractive electrochemical properties indicate that the carbon plate derived from pomelo peel is a promising electrode material for supercapacitors.

“…In the pomelo fruit, a hierarchical structure of pores is found in the thick peel that presumably protects the fruit from impact damage when falling from the high heights of citrus trees (Thielen et al 2013b). The main part of the peel (mesocarp) consists of a foam-like open structure with pores in the 100-400 μm range (Fig.…”

“…By organizing these features in a hierarchical fashion, living organisms are able to produce biological materials with properties and functionalities that would not be achievable otherwise using the same set of building blocks implemented at only one particular length scale. Examples in nature are abundant: strong and lightweight bones (Fratzl and Weinkamer 2007;Fratzl 2008a), stiff and tough seashells Espinosa et al 2009), fatigue-resistant tendon-bone interfaces (Genin et al 2009), fast-filtering marine sponges (Tompkins-MacDonald and Leys 2008;Leys et al 2011), impactabsorbing fruits (Thielen et al 2013b), self-cleaning plant leaves, sticky insect footpads, and colorful butterflies, among many others.…”

Hybrid and Hierarchical Composite Materials

The structural design of composite materials at multiple length scales is a widespread strategy found in biological materials to optimize opposing properties or to combine multiple functional properties in a unique material system. The combination of this hierarchical structuring approach with the vast chemical repertoire available in synthetic systems is expected to lead to man-made composites with unprecedented functionalities. Alternatively, hierarchical materials can potentially achieve sufficient strength and toughness even if made out of weaker environmentally-friendly or bioresorbable building blocks. Replicating the hierarchical design principle of biological systems in synthetic materials is an exciting challenge that has been tackled by researchers across different scientific communities. In this chapter, we present state-of-the-art examples on attempts to identify fundamental design principles of hierarchical natural materials and to then mimic these bioinspired concepts in man-made materials. Three selected structural features that can be independently designed at multiple length scales in biological materials are described as examples: (i) mechanical reinforcement, (ii) porosity, and (iii) topography. By comparing biological and man-made materials exhibiting these hierarchical features, we provide an overview on the limitations of currently exploited top-down and bottom-up manufacturing technologies and on the opportunities for the future development of hierarchical composites inspired by the unique multiscale structure of biological materials.

The structure of pomelo peel arouses research interest in recent years because of the outstanding damping and energy dissipating performance of the pomelo peel. Researchers found that pomelo peel has varying pore size through the peel thickness; the pore size gradient is one of the key reasons leading to superior energy dissipation performance of pomelo peel. In this paper, we introduce a method to model pomelo peel bioinspired foams with nonuniform pore distribution. We generate the skeletal open cell structure of the bioinspired foams using Voronoi tessellation. The skeleton of the bioinspired foams is built as three-dimension (3D) beam elements in a full-scale finite element model. The quasi-static and dynamic mechanical behaviors of the pomelo peel bioinspired foams could be derived through a finite element analysis (FEA). We illustrate our method using a case study of pomelo peel bioinspired aluminum foams under quasi-static compression and free fall impact circumstances. The case study results validate our method and demonstrate the superior impact resistance and damping behavior of bioinspired foam with gradient porosity for designers.
