Polymeric blends and filaments prepared from the blends are provided for improving isotropy in three-dimensional objects prepared by fused deposition modeling (FDM) processes. The polymeric blends include a high molecular weight (HMW) thermoplastic polymer and an additive comprising a low molecular weight (LMW) thermoplastic polymer. The HMW and LMW polymers can be the same type of polymer (e.g., poly(lactic acid)) or have at least one type of monomeric unit in common. The LMW polymer additive can have a molecular weight that is greater than the entanglement molecular weight and is about half the molecular weight of the HMW polymer or less. Inclusion of the LMW polymer can increase interfacial adhesion between filaments prepared from the blends. Also provided are three-dimensional objects prepared from a FDM process that have improved isotropic properties and methods of improving the isotropic properties of a three-dimensional object.

Synthetic fibers with enhanced soil resistance, yarns and carpets prepared from these fibers and compounds and methods for their production are provided.

The invention relates to lithium-based battery systems and, more particularly, to electro-spinable solution compositions, electro-spun sulfur-polymer fibers, e.g., wires and yarns, and their use in preparing high performance sulfur mattes, e.g., electrodes, for lithium-sulfur batteries with potential applications in small-scale mobile devices. The sulfur-polymer fibers have nanoscale dimensions and yarn-like morphology. The sulfur-polymer fibers can be prepared by co-dissolving sulfur and polymer in a solvent for forming the electro-spinable solution, and electrospinning the solution. The electrospun fibers can be used to form a composite that includes alternating layers of the electrospun fibers and polymer on a current collector.

The present invention relates to a method for producing nanofibers storing and transferring nitric oxide, and nanofibers produced thereby. The present invention may include: a filling step for filling a first material with nitric oxide; a synthesis step for synthesizing a second material having a functional group capable of covalently bonding to the first material; a sol-gel reaction step for carrying out a sol-gel reaction of the first material filled with nitric oxide with the second material to produce a gel; and an electrospinning step for electrospinning the gel to produce a nanofiber.

Polymeric materials are provided that are produced from a blend of hydrophilic and hydrophobic biodegradable polymers. The polymeric materials can form fibers, nonwoven fabrics, films, coatings, etc. A compound can be incorporated in the polymeric materials. The delivery of the compound can be controlled by diffusion of the compound from the polymeric material and during biodegradation of the polymeric material. The release rate is controlled by varying the composition of the polymeric material to control diffusion rates of the compound and/or biodegradation rate of the polymeric material. This technology provides methods for delivering and controlling release rates of pesticides and related compounds in agricultural and non-agricultural settings. When adhered to plants or plant parts, the polymeric materials can provide protection from insect and disease pests. In pellet or capsule form, pesticides can be delivered into seed furrows along with crop seeds, providing similar protection.
