TL;DR: The work deals with the fabrication of a novel hybrid polyvinylidene fluoride (PVDF)-polyaniline (PANI) membrane with graphene oxide (GO) and incorporation of PANI-GO as a nanofiller has significantly improved antifouling properties and a solvent content of the fabricated membrane.
Journal ArticleDOI
Coolmax/graphene-oxide functionalized textile humidity sensor with ultrafast response for human activities monitoring
Lulu Xu,Heng Zhai,Xiao Chen,Yulong Liu,Miao Wang,Zhangchi Liu,Muhammad Umar,Chengyu Ji,Zhongda Chen,Lu Jin,Zekun Liu,Qingwen Song,Pengfei Yue,Yi Li,Yi Li,Terry Tao Ye +15 more
TL;DR: It is discovered that the graphene-oxide (GO) functionalized Coolmax humidity sensor (GO-Coolmax) exhibits ultrafast response/recovery time (less than 0.6 s) and is insensitive to external pressure and temperature changes.
Journal ArticleDOI
Wet-spun bi-component alginate based hydrogel fibers: Development and in-vitro evaluation as a potential moist wound care dressing
Muhammad Umar,Azeem Ullah,Hifza Nawaz,Tanzeel Areeb,Motahira Hashmi,Davood Kharaghani,Kyu Oh Kim,Ick Soo Kim +7 more
TL;DR: The results showed that AHA fibers produced by the second method have better mechanical performance, high liquid absorption, and swelling percentage with a more controlled release of hyaluronic acid.
Journal ArticleDOI
Development and characterization of alginate-chitosan-hyaluronic acid (ACH) composite fibers for medical applications
TL;DR: It is concluded that ACH composite fibers can be produced by wet spinning and have adequate tensile properties, high % swelling, liquid absorption (g/g) and controlled release of hyaluronic acid for improved wound healing.
