Phase separation in poly(butylene terephthalate)-based materials prepared by solid-state modification
PublicationThe morphology of a series of poly(butylene terephthalate) (PBT)/fatty acid dimer diol (FADD)-based copolyesters prepared by solid-state modi fi cation (SSM) was studied. It was shown that in copolyesters containing less than 10 wt% FADD two different phases, i.e. a PBT crystalline phase and a PBT-rich amorphous phase, are present. The FADD residues were more or less homogeneously distributed throughout the interlamellar regions....

Poly(ferrocenylsilane-block-methacrylates) via sequential anionic and atom transfer radical polymerization.
PublicationArtykuł przedstawia sposób otrzymywania kopolimerów blokowych poli(ferrocenylosilanów) (PFS) i poli(metakrylanu metylu) (PMMA). W pierwszej kolejności syntezowany jest anionowo blok PFS, który po odpowiedniej terminacji służy jako makroinicjator dla syntezy bloku PMMA. Synteza ta jest realizowana przy użyciu polimeryzacji rodnikowej z przeniesieniem atomu (ATRP), katalizowanej przez kompleksy rutenu. Otrzymane w ten sposób kopolimery...

The influence of hard segment crosslinking on the morphology and mechanical properties of segmented poly(ester-urethanes)
PublicationPrównano właściwości i morfologie usieciowanych trójmetylolopropanem (TMP) i nieusieciowanych poliestrouretanów formowanych reaktywnie. W nieusieciowanych poliestrouretanach stwierdzono za pomocą AFM obecność agregacji domen segmentów sztywnych o wymiarze 70-380 nm. W usieciowanych poliuretanach zaobserwowano jedynie jednolicie rozmieszczone domeny segmentów sztywnych wielkości 20 nm. Właściwości mechaniczne wyraźnie różniły się,...

Insights into Compatibilization of Poly(ε-caprolactone)-based Biocomposites with Diisocyanates as Modifiers of Cellulose Fillers
PublicationThis study aimed to analyze the impact of cellulose fillers’ modification with diisocyanates on the performance of composites based on the poly(ε-caprolactone) (PCL) matrix. Four most commonly used diisocyantes (isophorone, hexamethylene, toluene, and methylene diphenyl) were applied as modifiers of cellulose fillers (5 and 15 wt% per mass of filler). Modified fillers were introduced in the amount of 30 wt% into the PCL matrix....

The influence of UV light on Performance of poly(methyl methacrylate) in regard to dyesensitised solar cells
PublicationNiskie kosztu produkcji i prosta budowa Barwnikowych Ogniw Słonecznych (ang.DSSC-Dye Sensitized Solar Cells) a także porównywalne wydajności czynią je konkurencyjnymi wsród komercyjnych technologii ogniw słonecznych. Jednym z elementów wchodzących w skład BOS jest transparentne szkło przewodzące stanowiące jego elektrody. Doskonała transparentność omozliwia zastosowanie polimeru PMMA jako substytutu transparaentnego szkła przewodzącego....

The influence of esterification time on the physicochemical properties of poly (glycerol sebacate-co- butylene sebacate)
PublicationThe study presents the results of the physicochemical properties of ester elastomer based on sebacic acid, glycerol and 1,4 - butanediol. The process of obtaining elastomers at variable esterification times of 14, 16 and 21 h is described. It was found that the material with an esterification time of 21 h is characterized by the best mechanical properties while maintaining high content of the gel fraction. In the technological...
