Novel hybrid systems based on poly(butyleneterephthalate) (PBT) and polyhedral oligomeric silsesquioxanes (POSS) have been prepared by applying the ring-opening polymerization of cyclic poly(butyleneterephthalate) oligomers. Two types of POSS have been used: one characterized by hydroxyl functionalities (named POSS-OH) and another without...

In this paper, it was developed the synthesis of a novel polymer additive potentially capable of modifying the features of electrospun fibers based on poly(L-lactide) (PLLA). Indeed, the above molecule, which was designed by taking into account both the features of the polymer matrix and the specific applications of the final material, was made...

A novel drug delivery system based on poly(l-lactide) (PLLA), graphite, and porphyrin was developed. In particular, 5,10,15,20-tetrakis(4-hydroxyphenyl)porphyrin (THPP) was chosen because, besides its potential as codispersing agent of graphite, it is a pharmacologically active molecule. Graphite nanoplatelets, homogeneously dispersed in both...

Stereocomplexed polylactide materials functionalized with poly(amido-amine) (PAMAM) dendrimer units were prepared by solution blending dendritic poly(d-lactide) (PDLA) star oligomers into a commercial poly(l-lactide) (PLLA), where the dendritic PDLA star oligomers were built up by ring-opening polymerization of d-lactide using a PAMAM dendrimer...

In this work, a novel method to prepare composite systems based on polylactide (PLA) and high surface area nano-graphite (HSAG) has been developed, consisting of the application of ionic liquids (ILs) as dispersing/exfoliating agents for nanofillers. Indeed, the proposed approach is easy as well as with a low environmental impact, involving...

In this work, novel graphite-based composites consisting of poly(l-lactide) (PLLA) and poly(ε-caprolactone) (PCL) immiscible blends are developed by means of a simple and low-environmental-impact method, which does not require the use of either solvents or graphite oxide. Indeed, the proposed approach relies on the preliminary dispersion of a...
