Abstract

The invention provides an infrared drying method used for preparing chitosan biological gel membrane. The infrared drying method used for preparing chitosan biological gel membrane comprises followingsteps: chitosan and an acetic acid solution are introduced into a beaker, water bath heating and stirring are carried out, glycerin is added after complete dissolving is achieved, full mixing is carried out, uniform tape casting into a glass mould is carried out, ultrasonic vibration defoaming is carried out, and drying in an infrared ray drying oven is carried out; chitosan and genipin are takenas raw materials to prepare a mixed solution, ultrasonic vibration defoaming and infrared ray drying treatment are carried out so as to obtain biological gel film with excellent performance, and thechitosan biological gel film production period is shortened greatly. According to the infrared drying method, genipin and chitosan are subjected to crosslinking reaction at a certain ratio, and glycerin is adopted for modification, the reaction is mild, is green, and is friendly to the environment. Compared conventional steam drying, the advantages are that: the infrared drying efficiency is high,the temperature is easy to control, heating is quick, resource is saved, and the safety is high.

Description

technical field [0001] The invention relates to a preparation method of a biogel film, in particular to a method for preparing a chitosan biogel film by an infrared drying method. Background technique [0002] As a kind of mechatronics product, ion gel electric actuator integrates the separation mechanism of traditional motor and gear transmission, and makes it lighter, smaller and more flexible. new ideas. At present, ionic electroactuated polymers can produce obvious size and shape changes under electrical excitation, and can generate corresponding electrical excitation signals under mechanical vibration, which has become the best choice for manufacturing actuators and sensors in the field of micro-robots. Compared with IPMC, the compatibility of ion gel electric actuators with carbon derivatives is more conducive to the preparation of flexible electrodes; compared with conductive polymers, ion gel electric actuators have faster response speed and various preparation form...
