- the main unit adopts a DC support motor and a rack and pinion drive system, and operates stably even at low speeds. Data is output from the plotter and recorded on chart paper.
- the sample (gel) used was a katsuyu and shaped to have the same length and width (20 imX 20 iM).
- the surface of the gel can be damaged by touching it with a hand or a Kimwipe, so care must be taken to avoid touching the surface to be actually rubbed during pretreatment.
- Substrates glass and acrylic plates to which the sample was to be rubbed were carefully washed with detergent beforehand, rinsed with distilled water, and air-dried before use.
- glass when used to some extent, contaminates the surface and repels water, and cannot be sufficiently washed with ordinary detergent. In such a case, it is advisable to soak the glass surface for a while in an alkaline alcohol solution obtained by dissolving a few percent of an alcohol such as a hydroxide rim in an alcohol solution such as methanol or ethanol, and then clean the glass surface.
- Gel unlike rubber, may slip off the initial installation position when a load is applied, so a frame was created and the gel was fixed by surrounding all sides. At this time, if the size of the fixing surface of the gel was deformed by applying a load, the gel was fixed by adjusting the frame according to the size after the deformation.
- the horizontal arm When installing the sample and weight, the horizontal arm must always be adjusted to be horizontal. Also in this case, depending on the gel, immediately after applying a load, the viscoelasticity may cause large cleaving, so the gel is left for at least 10 minutes after applying the load, and then the arm is leveled again. The measurement was started from.
- the load dependence experiment was performed by using one sample and changing the measurement conditions stepwise from low load to high load. When changing the conditions, the gel and the substrate were kept in contact.
- Tribogear is basically made on the premise of measurement in air. However, in the study of gel friction, measurement in oil is essential. For this reason, the following measures have been taken to enable measurement of friction in oil.
- the sample should be placed after the oil has been poured into the frame. It is advisable to add oil to the sample so that the entire surface of the sample is immersed (about lmm thick). The measurement is then performed in the same manner as in air.
- Fig. 2 shows an example of raw data when frictional force was measured using a tribo gear.
- (a) is the data at the time when the measurement was performed most clearly. Immediately after the start of measurement, static friction appears, after which the friction force is stable. In this experiment, this stable value was adopted as the friction force.
- the obtained friction force F W
- the obtained friction force F is calculated by dividing the obtained friction force F by the load W at that time. Obtained by dividing. The data after the friction force and friction coefficient became stable (after about 30 round trips) were used.

- FIGS. 3 and 4 The results of measuring the friction force and the friction coefficient of this organogel are shown in FIGS. 3 and 4, respectively (indicated by ⁇ in these figures). As can be seen from Fig. 3, it was confirmed that the frictional force dropped sharply when the load was about 2 X 10 1 N to about 4 X 10 Was done. The descent was about 1.1.
- Example 4 was repeated in the same manner as in Example 1 except that the viscosity was changed to a silicone oil having a viscosity of 1000 IM 2 / S (at 25) (Shin-Etsu Silicone Co., Ltd., silicone oil KF 96-1000, weight average molecular weight 25,000).
- IM 2 / S at 25
- silicone oil KF 96-1000 weight average molecular weight 25,000
- the organogel of Example 5 was obtained in the same manner as in Example 4, except that the amount of the crosslinking agent was changed to 0.5 mol% and the amount of the initiator was changed to 0.2 mol%.
- FIGS. 5 and 6 The results of measuring the frictional force and the friction coefficient of this organogel are shown in FIGS. 5 and 6, respectively (marked with ⁇ in these figures). As can be seen from Fig. 5, it was confirmed that the friction force sharply decreased when the load was about 0.5 X10 to about 2 X10. The descent was about 0.8.
- the organogel of Example 6 was obtained in the same manner as in Example 4, except that the amount of the crosslinking agent was changed to 1 mol% and the amount of the initiator was changed to 0.2 mol%.
- FIGS. 5 and 6 The results of measuring the friction force and the coefficient of friction for this organogel are shown in FIGS. 5 and 6, respectively ( ⁇ marks in these figures). As can be seen from Fig. 5, it was confirmed that the frictional force decreased sharply when the load was about 2X10 to about 4X10. The descent was about 5.
