Abstract Disposal of used diapers causes environmental pollution problems. Bank Sampah Bersinar, which is located in Bale Endah, Kabupaten Bandung, West Java Province, Indonesia, has made an effort to recycle and been operating since 2021 with a capacity around 5 tonnes per month. The process started by shredding the separating plastic fraction. fibre super absorbent polymer (SAP) slurry are th...

Recent developments in small-angle neutron scattering (SANS) investigations on polymer gels are reviewed by encompassing (i) volume phase transition and microphase separation, (ii) inhomogeneities in polymer gels, (iii) pressure dependence of hydrophobic interaction and (iv) structural characterization of super-tough gels. These developments owe much to the understanding of gel inhomogeneities ...

We consider the multidirectional swelling and drying of hydrogels formed from super-absorbent polymers water, focusing on elastic deformation caused by differential swelling. By modelling as instantaneously incompressible, linear-elastic materials considering situations in which there can be large isotropic strains (arising swelling) while deviatoric remain small, it is possible to describe acc...
