Sobolčiak, Patrik; Ali, Adnan; Hassan, Mohammad K.; Helal, Mohamed I.; Tanvir, Aisha; Popelka, Anton; Al-Maadeed, Mariam A.; Krupa, Igor; Mahmoud, Khaled A.... more authors ... less authors ( Public Library of Science , 2017 , Article)Novel 2D Ti3C2Tx (MXene)-reinforced polyvinyl alcohol (PVA) nanofibers have been successfully fabricated by an electrospinning technique. The high aspect ratio, hydrophilic surfaces, and metallic conductivity of delaminated ... -
An Enhancement of Compositional Stability of Phase Change Materials by Lamination with Aluminum Sheet
Kallingal, Nithusha; Sobolčiak, Patrik; Akbar, Himyan M.; Krupa, Igor; Novak, Igor; Popelka, Anton... more authors ... less authors ( MDPI , 2023 , Article)The wax leakage from shape-stabilized phase change materials (SSPCMs) is a limitation because it reduces their functionality. In this work, an enhancement of the compositional stability of SSPCMs formed by high-density ... -
Foamed phase change materials based on recycled polyethylene/paraffin wax blends
Sobolčiak, Patrik; Mrlik, Miroslav; Popelka, Anton; Minařík, Antonín; Ilcikova, Marketa; Srnec, Peter; Nogellova, Zuzana; Ouederni, Mabrouk; Krupa, Igor... more authors ... less authors ( MDPI , 2021 , Article)Foamed phase-change materials (FPCMs) were prepared using recycled linear low-density polyethylene (LLDPE) blended with 30 wt.% of paraffin wax (PW) and foamed by 1,1′-azobiscarbamide. The protection of pores’ collapse ... -
