Smart polymer hydrogel swelling experiment "Умные полимеры" и их реакция на нагревание #shorts

#NIPAm #Smartpolymer #shorts #shortvideo #УчителяКазахстана A novel hydrogel containing copolymer with NIPAm was immersed into hot water and after collapse of the material the gel was cooled down to room temperature. Набухание и коллапс/ сжатие гидрогеля "Умные полимеры" при перепадах температуры нагревание и охлаждение. Занимательный эксперимент по химии, ВМС. Основа явления коллапса полимера связано с повышением общей энтропии системы при нагревании. Құрамында NIPAm бар сополимері бар жаңа гидрогель ыстық суға батырылды және материал құлағаннан кейін гель бөлме температурасына дейін салқындатылды. by Dr Berillo Dmitriy Title A pH-responsive hydrogel for bio-active self-healing cementitious materials Fabian Steinacher, Shuai Nie Dmitriy Berillo, Manas Sarkar, Søren Dollerup Nielsen, Hans Røy, Jørgen Skibsted, Kasper Urup Kjeldsen Very soon the paper will be published about use of Smart polymers for Bio-active self-healing cementitious materials rely on bacterially induced calcium carbonate precipitation to heal microcracks. To produce such material, bacterial cells must be embedded in a carrier to protect and sustain their metabolic activity in the cementitious matrix. We therefore developed nine novel pH-responsive superabsorbent hydrogels .
