Гидратация и механические свойства гелей полиакриламида, содержащих линейный полисахарид агарозу
Аннотация
Настоящая работа посвящена изучению влияния различных факторов синтеза на гидрофильность и механические свойства гелей на основе ПАА и полисахаридов. В ходе работы были синтезированы гели на основе синтетических полимеров и полисахаридов. Для всех гелей измерены значения степени набухания и механические характеристики. Показано, что на свойства гелей оказывают влияние природа и концентрация мономера и сшивающего вещества, а также структура образующейся полимерной сетки. Между измерениями степени набухания и модуля Юнга полученных гелей наблюдается прямая корреляция.
This paper is devoted to studying the effect of various synthesis factors on the hydrophilicity and mechanical properties of gels based on PAA and polysaccharides. In the course of the work, gels were synthesized based on synthetic polymers and polysaccharides. The values of the characteristics of the swelling and mechanical characteristics were measured for all gels. It was shown that the nature and concentration of the monomer and the crosslinking agent, as well as the structure of the resulting polymer network, affect the properties of the gels. There is a direct correlation between measurements of the degree of swelling and the elastic modulus of the obtained gels.
