In coatings technology, the possibility of introducing specific characteristics at surface level allows for manufacture medical devices with efficient and prolonged antibacterial properties. This efficiency is often achieved by use a small amount molecules, which can fulfil their duty while limiting eventual releasing problems. The object this work was preparation characterization silver, titanium dioxide chitosan polyurethane-based coatings. Coatings three antibacterials were prepared using...
Novel, semicrystalline polyamides and co(polyamides) were synthesized from biobased sebacic acid (SA), 2,5-diamino-2,5-dideoxy-1,4;3,6-dianhydroiditol (diaminoisoidide, DAII) as well 1,4-diaminobutane (DAB), also known putrescine in nature. Low molecular weight obtained by melt polycondensation of the salts based on these monomers or interfacial polycondensation. In order to increase their weights polyamide prepolymers submitted a solid state polymerization (SSP) process. The chemical...
A study of the mechanical properties and crystallization behavior samples isotactic polybutene (iPB) different stereoregularity prepared with metallocene catalysts is presented. Stereoregular concentration rr defects lower than 2 mol % crystallize from melt by compression-molding fast cooling to room temperature in form II, whereas more stereoirregular surprisingly mainly III. The stereodefective iPB show interesting high ductility flexibility that increase increasing stereodefects, values...
The challenge to manufacture medical devices with specific antibacterial functions, and the growing demand for systems able limit bacterial resistance growth, necessitates development of new technologies which can be easily produced at an industrial level. object this work was study silver, titanium dioxide, chitosan composites realization and/or implementation biomedical devices. Thermoplastic elastomeric polyurethane selected used as matrix various functions introduced during processing...
Biobased polyamides synthesized from diaminoisoidide (DAII), 1,4-diaminobutane, and sebacic acid are investigated by FT-IR, 13C{1H} magic-angle spinning/cross-polarization (CP/MAS) NMR spectroscopy, WAXD. Their molecular conformation mobility undergo distinct changes as a function of temperature content in the compositions. The presence randomly distributed (DAII) reduces their hydrogen bond density affects trans/gauche conformer population. FT-IR CP/MAS were successfully employed to prove...
Introducing hydrogen bonds <italic>via</italic> amide motif incorporation in cross-linked epoxy coatings enhances local network mobility and ensures ability to relax mechanical stresses, possibly leading failure, preemptively without changes modulus adhesion.
ABSTRACT Stereoblock polypropylenes comprising of i PP and s segments are synthesized by polymerization the following binary system metallocenes: C ‐symmetric [2,7‐t‐Bu 2 (Flu) Ph C(Cp)ZrCl ] rac ‐Me Si(2‐Me‐4‐Ph‐Ind) ZrCl . Blends samples made either each catalyst individually (solution blend) with materials obtained mixed (reactor compared. The simultaneous presence MAO DEZ, enhancing fast reversible transfer growing chains between two active centers, leads to formation a stereoblock...
Chemistry is by definition the science of matter, transformation substances and for this reason also practical issues derived from its technological applications, has interested different populations since ancient times. The strong connection branch with industrial world promoted interest in development new materials that could substitute or improve traditional natural materials. Although not always been a direct consequence well specified research demand, (in fact many important discoveries...
