Abstract
Conducting electrospun fiber mats based on PLA and PAni blends were obtained with average diameter values between 87 and 1 006βnm with PAni quantities from 0 to 5.6 wt.β%. Structural characteristics of fiber mats were compared to cast films with the same amount of PAni and studied by SEM, SAXS, and AFM. Thermal properties of fiber mats and cast films were compared by DSC analyses. Mechanical properties of fiber mats were also evaluated. It was found that electrospinning process governs the crystal structure of the fibers and strongly affects fiber properties. New properties of PLA/PAni blends are reported due to the size fiber reduction.

## Abstract Poly(lactic acid) (PLA)/starch blends were prepared blending with dioctyl maleate (DOM). DOM acted as a compatibilizer at low concentrations (below 5%), and markedly improved tensile strength of the blend. However, DOM functioned as a plasticizer at concentrations over 5%, significantly
The zone-drawing (ZD) method was applied three times to the melt-spun poly(L-lactic acid) (PLLA) fibers of low molecular weight (M v Ο 13,100) at different temperatures under various tensions. The mechanical properties and superstructure of the ZD fibers were investigated. The resulting ZD-3 fiber h
