“…Being a natural biodegradable material, B. mori silkworm silk fibers generate no toxic waste in production and are cheaper to produce than synthetic fibers (Kelvin Loh and Willy Tan, 2011). These include B. mori, Antheraea mylitta, Philosamia synthia ricini, and Antheraea assamensis.…”

“…On cocooning for a couple of days, the pupae are then stifled by heat to prevent them from emerging out of their cocoons so that the silk can be reeled into yarns and woven into fabric (Kelvin Loh and Willy Tan, 2011).

“…The interfacial adhesion between them plays an important role in determining the performance of the composites. Some mechanical and physical properties of fibers are given in Table 8.1 (Ude et al, 2014;Kelvin Loh and Willy Tan, 2011). Hydrophilic nature takes a poor interfacial bond with polymer matrices, which decrease the mechanical properties of the composites.…”

“…Silk has a smooth, soft texture that is not slippery, unlike many fibers (Ude et al, 2014;Kelvin Loh and Willy Tan, 2011;Mahmoodi et al, 2010;Tanaka, 2002;Richard, 1955). The fibroin-heavy chain is composed mostly of beta sheets due to a 59-mer amino acid repeat sequence with some variations.…”

“…The high proportion (50%) of glycine, which is a small amino acid, allows tight packing and the fibers are strong and resistant to breaking (Kelvin Loh and Willy Tan, 2011). Fibroin is the structural center of the silk, and sericin is the sticky material surrounding it.…”

Organic light-emitting diodes (OLED) fabricated from all "natural" materials will lead to renewable, sustainable, and potentially inexpensive organic optoelectronics. Achieving this goal will require reimagining all the various aspects of the OLED with natural-based renewable materials. Here, we replace the common substrate, electrode, and hole injection layer in the OLED structure with cellulose, gold, and the DNA nucleobase adenine. Gold films are used as semitransparent electrodes on plant-based cellulose substrates, providing flexible anodes that are highly conductive without annealing. A lift-off fabrication method (template stripping) employed UV curable epoxy to transfer patterned gold from silicon to cellulose. The gold has excellent adhesion to the epoxy (is not damaged when wiped), and the two serve as a smoothing layer for the cellulose substrate, resulting in very uniform OLED emission. DNA and DNA nucleobases are demonstrating to be versatile materials in natural electronics due to their wide energy level range. We found that adenine as a hole injection layer on gold can overcome challenges of charge injection into the organic semiconductors, increasing OLED maximum luminance and emission efficiency 4−5× on both glass and cellulose substrates through increases in current (hole injection): on glass, from ∼12500 to 45000 cd/m 2 and from 5 to ∼32 cd/A; on cellulose, from ∼2000 to 8400 cd/m 2 and from 3 to ∼14 cd/A. These results expand the utility of the DNA bases for naturally based electronics and demonstrate practical methods to integrate cellulose as a biodegradable substrate.

This work describes for the first time the flexural and compression mechanical behavior of Manicaria saccifera fibers–polymer matrix composites. These lignocellulosic fibers are obtained from a palm of natural occurrence at the Amazon region. Specifically here the fibrous natural mat that protects the fruits’ palm is used. The results obtained are comparable to the data from other lignocellulosic fiber–polymer matrix composites, demonstrating the feasibility of using Manicaria saccifera fibers as reinforcement. The wear behavior of the composites was also analyzed and their use as parquet floor is pointed out as a possibility.
