Abstract Traditional Chinese medicine (TCM) has a long history and is widely used to prevent and treat various diseases. With the development of modern technology, an increasing number of active ingredients—such as curcumin, berberine, and baicalin—have been identified and validated within TCM. Concurrently, the emergence of nanotechnology has led to the discovery of numerous nanomedicines based on the self-assembly of active ingredients from TCM. Polymer materials can enhance the bioavailability of these active compounds and reduce their toxic side effects. Moreover, compared to synthetic polymers, natural polymer materials offer advantages such as non-toxicity and high biosafety… More >

Abstract Nowadays, the development of effective bioplastics aims to combine traditional plastics’ functionality with environmentally friendly properties. The most effective and durable modern bioplastics are made from the edible part of crops. This forces bioplastics to compete with food production because the crops that produce bioplastics can also be used for human nutrition. That is why the article’s main focus is on creating bioplastics using renewable, non-food raw materials (cellulose, lignin, etc.). Eco-friendly composites based on a renewable bioplastic blend of polybutylene adipate-co-terephthalate, corn starch, and poly(lactic acid) with reed and hemp waste as a filler.… More > Graphic Abstract

Abstract Selective laser sintering (SLS) is one of the mainstream 3D printing technologies. A major challenge for SLS technology is the lack of novel polymer powder materials with improved Z-direction strength. Herein, a series of polymer materials with covalent adaptable networks structure were utilized to solve the challenge of SLS. To verify this concept, novel kinds of cross-linked polyurethanes (TPU) or polydimethylsiloxane (PDMS) elastomers containing dynamic covalent bonds including halogenated bisphenol carbamate bonds [1], hindered pyrazole urea bonds [2] or Diels–Alder bonds [3] were synthesized. The obtained dynamic TPU or PDMS exhibited excellent mechanical strength and More >

Abstract A triethylenetetramine epoxy mixture was synthesized through the reaction of a low-molecular-weight liquid epoxy resin with triethylenetetramine (TETA). Then triethyltetramine (TETA) was injected dropwise into a propylene glycol methyl ether (PM) solution for chain extension reaction. A hydrophilic and flexible polyether segment was introduced into the hardener molecule. The effects of TETA/DGEPG, reaction temperature and reaction time on the epoxy conversion of polyethylene glycol diglycidyl ether (DGEPG) were studied. In addition, several alternate strategies to add epoxy resin to the high-speed dispersion machine and synthesize MEA DGEBA adduct (without catalyst and with bisphenol A diglycidyl More >

Abstract Composite fabrics based on Polytetrafluoroethylene (PTFE) polymer displays several notable properties. They are waterproof, windproof, permeable to moisture and thermally insulating at the same time. In the present study, PTFE fibers are used as raw material to make fiber membranes. The film is formed by crisscrossing interconnected fiber filaments and the related air permeability: tensile creep characteristics and other properties are tested. The results show that the pore size, thickness, and porosity of the film itself can affect the moisture permeability of the film. The water pressure resistance of the selected fabric is 8.5 kPa, More >

Abstract In this study, it is shown how recycled rubber and waste plastics can modify the softening point and penetration of asphalt traditionally used for highways. It is shown that the modified asphalt can meet the performance index requirements when the components are present with a certain proportion or relative ratio (1:3.5). The dispersion process of the masterbatch in base asphalt can effectively be implemented, with good results and a smaller mixing time. The proposed approach may be regarded as a good strategy to achieve energy savings and protection of the environment. More >
