Additive manufacturing using polyamide-12

open access: yes
Santrauka Laurynas Peciukonis ADITYVIOJI GAMYBA PANAUDOJANT POLIAMIDĄ–12 Selektyvus lazerinis sulydymas (angl. selective laser sintering, SLS) jau ilgai įsitvirtinusi adityvios gamybos technologija, tačiau jos kaina iki šios išlieka aukšta dėl sudėtingos prietaisų konstrukcijos lyginant su kitais tokios gamybos būdais.

Statistical evaluation of nylon chemical recycling through acidolysis

open access: yesPolymer International, EarlyView.
Sustainable PA6 recycling through acidolysis enabled temperature‐driven depolymerization, modeled by regression analysis. Recycled products successfully replaced up to 30% monomer while preserving PA6 chemical composition or crystalline structure. Abstract This study focuses on the sustainability of plastics reporting the recycling of polyamide (PA ...

Electrospun fibrous sorbents for the removal of uranium and americium from aqueous media

open access: yesPolymer International, EarlyView.
Polymethacrylate‐based electrospun microfibers with tertiary amino functionalities are evaluated as adsorbents for U‐232 and Am‐241 in both simplified and complex (seawater) water matrices, highlighting their ability for efficient actinide removal. Abstract Polymethacrylate‐based electrospun microfibers containing tertiary amino functionalities were ...

The Evolution of Crystal Structure in Polypropylene as It Goes From Pellet to Powder to Print in Powder Bed Fusion Additive Manufacturing

open access: yesJournal of Polymer Science, EarlyView.
Small angle x‐ray scattering provides insight into the change in crystalline structure in polypropylene molecular weight blends as the polypropylene is transformed from commercial pellets to a powder suitable for powder bed fusion (PBF), and then further transformed to a part printed by PBF.
