A solid electrolytic capacitor containing a capacitor element is provided. The capacitor element contains a sintered porous anode body, a dielectric that overlies the anode body, a pre-coat that overlies the dielectric, and a solid electrolyte that overlies the pre-coat. The solid electrolyte includes a conductive polymer having repeating units derived from an aniline monomer having the following general formula (I):

Solid electrolytic capacitor containing polyaniline

A capacitor that is capable of exhibiting good electrical properties even under a variety of conditions is provided. More particularly, the capacitor contains a sintered porous anode body, a dielectric that overlies the anode body, and a solid electrolyte that overlies the dielectric. The solid electrolyte contains an inner layer and an outer layer, wherein the inner layer is formed from an in situ-polymerized conductive polymer and the outer layer is formed from pre-polymerized conductive polymer particles. Further, the in-situ polymerized conductive polymer is formed from an alkylated thiophene monomer.

The invention relates to a self-supporting, biodegradable film comprising a C-C-acylated derivative of hyaluronic acid according to the general formula (I), where R is Hor Na, and where Ris H or &#x2014;C(&#x2550;O)CH, where x is an integer within the range from 9 to 21 and y is an integer within the range from 11 to 43 and CHis a linear or branched, saturated or unsaturated C-Cchain, wherein in at least one repeating unit one or more of Ris &#x2014;C(&#x2550;O)CHand where n is within the range from 12 to 4000; a method of preparation thereof and use thereof. 

Self-supporting, biodegradable film based on hydrophobized hyaluronic acid, method of preparation and use thereof

The invention relates to the preparation and the use of &#x3b1;,&#x3b2;-unsaturated aldehydes in the structure of sulfated polysaccharides. It concerns the derivatives with a conjugated double bond in the 4th and 5th positions of the galactopyranose part situated in the 6th position with respect to the aldehyde, according to the general structural formula (I) or its hydrated form according to the general structural formula (II). The preparation of these derivatives derives from sulfated polysaccharides containing a galactopyranose ring sulfated in the 4th position that is bound in the polymer chain via &#x3b1;(1&#x2192;3) or &#x3b2;(1&#x2192;3) O-glycosidic bond. In the described solution, the sulfated polysaccharides undergo a regio- and chemoselective oxidation to form C6-saturated aldehyde, which, via a direct elimination of the sulfate group, provides the &#x3b1;,&#x3b2;-unsaturated derivative according to the general formula (I) or (II). The described solution is technically advantageous, because it leads directly to &#x3b1;,&#x3b2;-unsaturated aldehydes, without any elimination agents, higher temperature, or isolation of intermediates during the synthesis. The conjugation in the structure of &#x3b1;,&#x3b2;-unsaturated aldehyde allows, under physiological conditions, to bind a wide variety of biocompatible amines in the structure of the sulfated polysaccharides. The proposed method allows to prepare materials suitable for pH-responsive drug delivery systems, or for the preparation of scaffolds in tissue engineering or regenerative medicine. Formulae for the abstract (I), (II) above, where R is OH, O&#x2014;SO&#x2014;OH, O&#x2014;SO&#x2014;ONa, or NH&#x2014;Ac.
