Special Issue Information

Dear Colleagues,

Advanced natural polymers are widely applied in various engineering fields, including drug delivery, food, and functional materials, which present high biodegradability, good biocompatibility, and external stimuli reacted physiological activity. Therefore, it is of great practical significance and application value to clearly analyze the chemical structure of polymer composites and accurately reveal the structure–activity relationship for the design and development of more functional materials and smart drugs that can be used in various engineering applications, such as biological and environmental fields.

The aim of this Special Issue is to gather the latest original research studies that involve natural polymer materials. We look forward to receiving your manuscripts in this field. Research articles and review articles are both welcome.

Water evaporation-driven energy harvesting is an emerging mechanism for contributing to green energy production with low cost. Herein, we developed polyacrylonitrile (PAN) nanofiber-based evaporation-driven electricity generators (PEEGs) to confirm the feasibility of utilizing electrospun PAN nanofiber mats in an evaporation-driven energy harvesting system. However, PAN nanofiber mats require a support substrate to enhance its durability and stability when it is applied to an evaporation-driven energy generator, which could have additional effects on generation performance. Accordingly, various support substrates, including fiberglass, copper, stainless mesh, and fabric screen, were applied to PEEGs and examined to understand their potential impacts on electrical generation outputs. As a result, the PAN nanofiber mats were successfully converted to a hydrophilic material for an evaporation-driven generator by dip-coating them in nanocarbon black (NCB) solution. Furthermore, specific electrokinetic performance trends were investigated and the peak electricity outputs of Voc were recorded to be 150.8, 6.5, 2.4, and 215.9 mV, and Isc outputs were recorded to be 143.8, 60.5, 103.8, and 121.4 μA, from PEEGs with fiberglass, copper, stainless mesh, and fabric screen substrates, respectively. Therefore, the implications of this study would provide further perspectives on the developing evaporation-induced electricity devices based on nanofiber materials. Full article
